* La pagina [[Compile_on_Linux/Unix/it|Compilare su Linux/Unix]] è stata rivista per spiegare meglio i requisiti per compilare su diverse distribuzioni Linux. Poiché molti sviluppatori utilizzano sistemi basati su Debian, questa sezione ha ricevuto la massima attenzione. Gli utenti di altre distribuzioni Linux sono incoraggiati a mantenere la documentazione per la loro particolare distribuzione. Anche [[CompileOnWindows/it|Compilare su Windows]] è stato riscritto per spiegare come usare il LibPack per la compilazione.

Dopo 2,5 anni di sviluppo, l'oggetto "[[Std_LinkMake/it|Link]]", o più formalmente {{incode|App::Link}}, è stato introdotto in FreeCAD. Questo è un tipo speciale di {{incode|App::DocumentObject}} con alcune proprietà che, si spera, consentiranno di semplificare gli assemblaggi.

Un "Link" consente agli oggetti di utilizzare i dati di un altro oggetto, come la geometria o anche la loro rappresentazione visiva 3D, negli stessi file o in file diversi. Può essere pensato come un leggero clone assoluto o come lo stesso oggetto che vive in due "istanze" diverse. Alcune funzionalità offerte da un "Link" sono già presenti in alcuni ambienti come [[Arch Workbench/it|Arch]] e [[BIM Workbench/it|BIM]] ([[Draft Clone/it|cloni]], [[Arch_Reference/it|riferimenti esterni]] ), ma l'implementazione di "Link" è al livello principale e può quindi essere utilizzato da tutti gli ambienti in diversi modi.

"Assembly3" is an assembly workbench written in Python by realthunder, that makes use of the "Link" functionality. The workbench served as a testbed for the "Link" component during its development. While Assembly3 is still not officially part of FreeCAD, with the inclusion of "Link", it is a matter of time for Assembly3 to be provided as an installable add-on, just like [[A2plus Workbench|A2plus Workbench]] is provided currently.

This tool was particularly developed to help edit the shape of [[Arch Wall|Arch Walls]] that are based on [[Draft Wire|Draft Wires]]. When various walls are selected, and the tool is used, the base wires automatically become visible, and display their nodes prominently.

| The introduction of the [[App_Link|App::Link]] object made it possible to create arrays which have many exact references to an existing object instead of shape duplicates (simple copies). This results in more memory efficient arrays. This is possible with the new [[Draft_LinkArray|Draft LinkArray]] and [[Draft_PathLinkArray|Draft PathLinkArray]] tools. [[Draft_LinkArray|Draft LinkArray]] works in its tree modes, "ortho", "polar", and the new "circular" mode, which was introduced in a separate commit.

After the creation of the Link arrays, a new command called [[Draft OrthoArray|Draft OrthoArray]] now replaces both [[Draft_Array|Draft Array]] and [[Draft_LinkArray|Draft_LinkArray]]. This [[Draft OrthoArray|Draft OrthoArray]] is used to create exclusively orthogonal arrays. It shows a task panel similar to [[Draft_PolarArray|Draft PolarArray]] and [[Draft_CircularArray|Draft CircularArray]]. Therefore, from the toolbar it is now possible to create "orthogoanl", "polar" and "circular" arrays from separate buttons. Moreover, the array buttons are collected in a group so that they are organized.

| New icons were provided for the Draft objects in the [[tree_view|tree view]]. The objective is to more quickly distinguish the objects at a glance, particularly if the default label is changed. This makes it easier to recognize objects which are lines, curves, geometrical elements, linear, radial, or angular dimensions, or other objects.

In addition, all icons were converted to the new standard pixel resolution of 96 dpi, and were saved as Plain SVG, so that we don't introduce non-standard SVG tags.

The expectation is that Trails serves as a FreeCAD based graphical interface for PyTrails, while PyTrails remains a general purpose library that can be used outside FreeCAD in other projects.

| After working with Trails and Turns, the author decided to split the tracker code into a separate library called '''pivy_trackers'''. This is a general library that could be included in other workbenches to generate tracker objects and perform actions in the scene, like dragging lines, dragging points, and changing certain geometrical elements on the fly.

Revision as of 21:28, 19 March 2020

This page tracks new features as they are added to the development version of FreeCAD, which is currently 0.19. When the 0.19 feature freeze happens, delete these messages, and don't add more features to this page. FreeCAD 0.19 is expected to be released in 2020.

Are features missing? Mention them in the Release notes for v0.19 forum thread.

See Help FreeCAD for ways to contribute to FreeCAD.

FreeCAD 0.19 was released on DD Month 2020, get it from the Download page. This is a summary of the most interesting changes. The complete list of changes can be found in the MantisBT bugtracker FC 0.19 changelog.

Le note di rilascio delle versioni precedenti di FreeCAD sono disponibili in Funzioni di FreeCAD.

Simpson and Shipton short stroke steam engine circa 1845, using horizontal rotating piston, by "un1corn", Users Showcase.

Punti salienti


Horizontal 4 cylinder rotary valve steam engine, by "un1corn", Users Showcase.


Preliminary design of MAORY, an adaptive optics (AO) module for the European Extremely Large Telescope (E-ELT); here it is mounted on the E-ELT Nasmyth platform.

This assembly was made by "Zolko", author of the new Assembly4 Workbench, which uses the new powerful App Link object to import thousands of different parts and subassemblies, arranging them in specified positions by means of mathematical expressions. See Users Showcase.

For this model, the parts were not designed in FreeCAD, they were just imported in STEP format, and subsequently arranged with Assembly4.

Aspetti generali

Con oltre 2000 commit nel ramo master dalla versione 0.18, questa è una delle versioni più estese di sempre, con diversi nuovi componenti come il nuovo oggetto "App::Link", oltre a molti nuovi strumenti nell'ambiente TechDraw che rendono FreeCAD ancora più potente per la modellazione e l'assemblaggio di solidi 3D. Inoltre, l'ecosistema di FreeCAD ha continuato a crescere con ulteriori ambienti di lavoro esterni specializzati.

Python 3 e Qt5

Lo sforzo di migrare da Python 2 e Qt4 a Python 3 e Qt5 è sostanzialmente completo e la maggior parte degli sviluppatori è passata agli strumenti di Python3 e Qt5.

Indubbiamente ci sono bug imprevisti; questi saranno affrontati man mano che vengono segnalati. Qualsiasi dipendenza esistente da Python 2 o Qt4 non sarà supportata oltre il 1 ° gennaio 2020, data in cui Python 2 diventerà ufficialmente non più supportato dalla Python Foundation. Notare che alcuni componenti aggiuntivi non sono stati ancora portati su Python3 e Qt5. Ciò può essere dovuto a diversi motivi tra cui la mancanza di tempo da parte dei loro sviluppatori o dipendenze interrotte che potrebbero non essere facilmente risolvibili o semplicemente perché l'addon è considerato obsoleto. Le persone interessate alla migrazione di un particolare ambiente di lavoro o strumento sono incoraggiate a partecipare al forum di FreeCAD; vedere anche Python3 and Qt5 Compatible Addon Workbenches (in preparazione per 0.18).

Alcuni problemi

Fixed issue with Std Part containers visibility when the viewport is displayed in full screen in Qt5:

Sviluppo

Documentazione

  • La pagina Compilare su Linux/Unix è stata rivista per spiegare meglio i requisiti per compilare su diverse distribuzioni Linux. Poiché molti sviluppatori utilizzano sistemi basati su Debian, questa sezione ha ricevuto la massima attenzione. Gli utenti di altre distribuzioni Linux sono incoraggiati a mantenere la documentazione per la loro particolare distribuzione. Anche Compilare su Windows è stato riscritto per spiegare come usare il LibPack per la compilazione.
  • La pagina Documentazione del codice sorgente è stata ripulita per spiegare meglio come produrre la documentazione di programmazione (API) partendo da C++ e Python.
  • La pagina Doxygen è stata rivista ed estesa per fornire maggiori dettagli sulla sintassi utilizzata nei file C++ per produrre la documentazione di programmazione.
  • Anche la pagina Gestione del codice sorgente è stata rielaborata con descrizioni ed esempi migliori sull'uso di git per gestire i rami e contribuire al codice.
  • La pagina Ambienti di lavoro esterni è stata riorganizzata, in modo da elencare tutti gli ambienti ricchi di funzionalità e disponibili al pubblico. Se si desideri aggiungere un workbench a questa pagina, comunicarlo nel forum e fornire le informazioni di supporto come il manuale dell'utente, le pagine wiki e un link al suo repository. Quindi spingere per includerlo in Addon Manager.

Limitazioni note

  • Black screen due to video card drivers, while running FreeCAD inside a virtual machine; issue #3939.
  • Logitech Wingman USB joystick can cause erratic behavior when spinning and zooming in the view; forum discussion.
  • Gesture navigation is fully supported for Windows but yet to be maintained in Linux and MacOS. Problem: the developer, DeepSOIC, doesn't have a MacOS machine with its special trackpad, and hasn't tested it on Linux either; forum discussion.

Interfaccia utente

The navigation cube got a few retouches; now it uses transparency to be easier on the eyes, and the arrows are bigger to improve clicking on them.

Forum discussion, pull request #2076.

New COIL icon theme developed by user 1D_Inc. This is a minimalistic icon set inspired on Blender's 2.8 outline-style icons (a coil of threads or strands alludes to the appearance of the icons). The intention is to have professional-looking icons that can be used with different color themes, including light, dark, and monochrome.

Forum discussion 1 (old thread), discussion 2 (main thread), 1D_SVG_Tools repository.

New icon theme management developed by user triplus.

Forum discussion.

New dark stylesheet developed by user userzmp2000.

Forum discussion, BlenderLike-dark.qss.

Dark themes by user pablogil. Blue, green, and orange variations, which are darker than previous templates.

App::Link e assemblaggio

L'oggetto "App::Link" consente il collegamento leggero di oggetti in un documento e da documenti esterni.

Dopo 2,5 anni di sviluppo, l'oggetto "Link", o più formalmente App::Link, è stato introdotto in FreeCAD. Questo è un tipo speciale di App::DocumentObject con alcune proprietà che, si spera, consentiranno di semplificare gli assemblaggi.

Un "Link" consente agli oggetti di utilizzare i dati di un altro oggetto, come la geometria o anche la loro rappresentazione visiva 3D, negli stessi file o in file diversi. Può essere pensato come un leggero clone assoluto o come lo stesso oggetto che vive in due "istanze" diverse. Alcune funzionalità offerte da un "Link" sono già presenti in alcuni ambienti come Arch e BIM (cloni, riferimenti esterni ), ma l'implementazione di "Link" è al livello principale e può quindi essere utilizzato da tutti gli ambienti in diversi modi.

Il componente "Link" è stato pensato e sviluppato quasi interamente dall'utente realthunder. Le motivazioni e le implementazioni progettuali alla base di questo progetto sono descritte nella sua pagina GitHub, Link. Per realizzare questa funzione, sono state apportate diverse modifiche fondamentali a FreeCAD; queste modifiche sono ampiamente documentate in Core-Changes.

La storia di "Link" può essere rintracciata tramite alcune discussioni essenziali del forum:

Finally, the pull request and merge happened:

The "App Link" object prepares FreeCAD for the phase that was scheduled to happen after the redesign of PartDesign in FreeCAD 0.17, which is working with assemblies.

Assembly3 is an assembly workbench written in Python by realthunder, that makes use of the "App Link" functionality. The workbench served as a testbed for this component during its development. While Assembly3 is still not officially part of FreeCAD, with the inclusion of "App Link" in the master branch, it is a matter of time for Assembly3 to be provided as an installable add-on, just like A2plus and Assembly4 are provided currently.

Core system, App, Base, and Gui namespaces

Beside the introduction of App Link, the "LinkMerge" branch also introduced some changes visible to the user with regards to object properties, expressions, visual selection, and the tree view. These are described in the Core-Changes page.

Dynamic properties can be added to any C++ or Python object. This can make macros such as Macro PropertyMemo obsolete.

Forum discussion | Animated gif

These dynamic properties were added in the App Link merge; pull request #2350.
Selected elements hidden by other elements are highlighted to indicate their position within the model.

These selection enhancement were also introduced in the App Link merge; pull request #2350.

After two years being stalled, there have been improvements in the way the program handles backup files. Now they can include a timestamp in the format %Y%m%d-%H%M%S, instead of a simple number. This can be set in the preferences editor.

Forum discussion, pull request #1148.

Addon Manager

The Addon Manager was upgraded; it is now able to display more complete information on all external workbenches and macros, and show an icon for each of them. It also allows checking for updates on start, and using custom repositories.

Forum discussion.

It will also show information on whether the addon is obsolete, already installed, or available for update.

Forum discussion, pull request #2605.

Ambiente Arch

The Arch Site tool once more is able to produce sun path diagrams if the given latitude, longitude, and declination are provided. This requires Pysolar 0.7 or above, and only works with Python 3.

Forum discussion, commit 2177f4437, commit c05bc0990.

The Arch Site tool now can display a compass to show the direction of the "true North" (declination) in the model. By the default, North is aligned to the Y axis. This is useful when working in real world coordinates.

Forum discussion, pull request #2111, commit ff1fb11af, pull request #2360.

The Arch SectionPlane tool now has the ability of clipping the view, to act as a camera.

Forum discussion, commit 9a64f3fad9.

The Arch Fence tool was added to produce fence objects starting from a post and a path.

Forum discussion, pull request #2151, pull request #2173, pull request #2263, pull request #2270.

Arch Fence in action.

Improvements in the Reinforcement Addon, which extends the Arch Rebar tool.

Automated reinforcement graphical user interface: the intention is to facilitate the automatic creation of simple and complex rebars. This development was carried out as a Google Summer of Code 2019 project: Suraj_Dadral/gsoc_proposal.

Forum discussion, FreeCAD-Reinforcement (master code), SurajDadral/FreeCAD-Reinforcement (development fork).

New Arch CutLine tool to cut solid objects, like Arch Walls and Arch Structure, using an edge, like a Draft Line. This works similar to the existing Arch CutPlane.

Forum discussion | Pull request #2701, #2870.

Ambiente Draft

The Draft Edit tool was upgraded to allow editing many Draft objects at the same time, and also display better trackers.

Forum discussion | Animated gif | Pull request #1968, commit 272a8dfcc9, commit 7de2248bb, pull request #2108, pull request #2430.

The tool was also moved into its own module: commit a4e2df115d, commit c351b9094.

New Draft SubelementHighlight tool to highlight the nodes and edges of certain objects, like Draft Wires, in order to edit them using modifiers like Draft Move, Draft Rotate, and Draft Scale. It allows you to select multiple objects to edit instead of just one. Once the objects are highlighted, you can select specific sub-elements, vertices and edges, and transform (move, rotate, scale) only these.

This tool was particularly developed to help edit the shape of Arch Walls that are based on Draft Wires. When various walls are selected, and the tool is used, the base wires automatically become visible, and display their nodes prominently.

Forum discussion | Video demonstration 1, 2 | Pull request #1975.

New Draft CubicBezCurve tool, to create 3rd degree Bezier curves in a way similar to Inkscape.

Forum discussion | Animated gif | Pull request #2072.

New Draft Arc 3Points tool, to create circular arcs by specifying three points through which the arc passes. Originally developed in the BIM Workbench and then migrated to Draft.

Forum discussion, commit 4f19a65559, commit 0b905fade0, pull request #2286.

A proper command line interface as well as unit test are also provided.

Pull request #3004, #3005.

New Draft Layer tool that replaces the seldom used Draft VisGroup, providing a true layer system as it exists in other CAD systems. Draft Layer supports adding objects by drag-and-drop, controls object visibility and, optionally, object color.

Forum discussion (development), forum discussion (announcement), commit 5ee99ca4ee, commit 36bc48c9bf.

Substantial reworking of Draft SVG routines to improve inclusion of 2D projections in TechDraw pages. This benefits tools like Draft Shape2DView and Arch SectionPlane, when used with TechDraw NewDraft and TechDraw NewArch.

Forum discussion.

New Draft Fillet tool that creates a fillet (rounded corner) or a chamfer (straight line) between two simple Draft Lines.

Forum discussion | Pull request #2441, #2492.

The introduction of the App Link object made it possible to create arrays which have many exact references to an existing object instead of shape duplicates (simple copies). This results in more memory efficient arrays. This is possible with the new Draft LinkArray and Draft PathLinkArray tools. Draft LinkArray works in three modes, "ortho", "polar", and the new "circular" mode, which was introduced in a separate commit.

Pull request #2350.

After the creation of the Link arrays, a new command called Draft OrthoArray now replaces both Draft Array and Draft LinkArray. This Draft OrthoArray is used to create exclusively orthogonal arrays. It shows a task panel similar to Draft PolarArray and Draft CircularArray. Therefore, from the toolbar it is now possible to create "orthogonal", "polar" and "circular" arrays from separate buttons. Moreover, the array buttons are collected in a group so that they are organized.

Forum discussion | Pull request #2988, #2972.

New Draft PolarArray tool to create polar arrays directly. Previously, the same could be done by using the old Draft Array command, and then modifying the properties of the created object.

This Draft PolarArray tool can create the new App Link objects or the traditional copies.

Forum discussion | Pull request #2824.

The Array object has a new "circular" mode. This is controlled by new properties: DatiRadialDistance, DatiTangentialDistance, DatiNumberCircles, and DatiSymmetry.

Forum discussion | Pull request #2585.

Moreover, a new Draft CircularArray tool was developed to create these circular arrays directly. This tool can create the new App Link objects or the traditional copies.

Forum discussion | Pull request #2824.

The unit tests of the workbench were rewritten and expanded, so that now it is easier to test for errors and regressions when new code is merged.

Forum discussion | Pull request #2668, #2727, #2881, #3005.

Also, a script is provided in Mod/Draft/drafttests/draft_test_objects.py, that produces a test file with most objects of the workbench. This file is useful to learn scripting in Draft, and can also be used to test regressions in the underlying code of the objects.

Forum discussion | Pull request #3012.

New icons were provided for the Draft objects in the tree view. The objective is to more quickly distinguish the objects at a glance, particularly if the default label is changed. This makes it easier to recognize objects which are lines, curves, geometrical elements, linear, radial, or angular dimensions, or other objects.

In addition, all icons were converted to the new standard pixel resolution of 96 dpi, and were saved as Plain SVG, so that we don't introduce non-standard SVG tags.

Forum discussion | Pull request #3051, #3058, #3060, #3070, #3170.

Undergoing efforts to split tools into their own module files to ease maintenance of the codebase for the future, and facilitate the addition of new tools.

Forum discussion, overall structure.

Some of the functions and classes that have already been moved: commit 5ee99ca4ee (Draft Layer), commit 16c26cb3b1 (Draft Edit), commit 9fb6aec313 (Draft SelectPlane), pull requests #2823 (GuiCommandBase), #2829 (utilities), #2830 (GUI utilities), #2831 (ToDo class), #2832 (translate function), #3091 (Draft Snap), #3092 (Draft Trackers), #3094 (Draft SelectPlane), #3095 (Draft ShapeString task panel), #3096 (Draft Scale task panel), #3097 (Draft Edit).

This is a work in progress that requires advancing carefully as we aim to maintain compatibility with previous versions of Draft. Full refactoring may take years at the current pace. We invite enthusiastic developers to join the effort.

Altro

  • The Draft Wire tool now is called "Polyline" in the menu, instead of "DWire"; all options and functionality remain the same, so this doesn't break compatibility; commit 39e748229e.
  • A "DraftEditPickRadius" preference was added to control the area of influence of the pointer when picking vertices in edit mode Draft Edit; forum discussion, pull request #2642, issue #4162.
  • Undergoing efforts to document the Python source code (adding complete docstrings), in order to produce better programming documentation that can be used by both users and developers. See Source documentation for instructions on generating the documentation with Doxygen.
  • The "Toolbar mode" when launching the Draft tools has been removed. This was an interface that was used in the past but became obsolete as the task panel became the predominant interface; forum discussion, pull request #2973.

Ambiente FEM

After half a year in development and testing the "femconcrete" branch was added to the FEM Workbench. This provides tools to estimate the level of reinforcement required in a concrete structure to prevent brittle failure under tension or shear. In essence, it is a post processing routine for the CalculiX solver, which calculates the principal tensile stresses in the concrete from an elastic analysis and uses those to determine the minimum reinforcement in the three coordinate directions required to prevent failure.

Forum discussion, Analysis of reinforced concrete with FEM (tutorial) | Pull request #2267.

After a few months in development the "fcFEM" macro was published. It implements a finite element solver entirely in Python. Its author designed it to overcome the limitations of other external solvers, like CalculiX and z88. Some of the intended improvements include creating mixed mesh analyses, improved beam and shell elements, arc-length control for overcoming limit points in elastic-plastic analyses, implementation of zero-thickness interface elements for different applications, and others.

In due time this solver could be distributed together with the FEM Workbench, meaning that the FreeCAD project would have its own finite element solver for doing mechanical and structural analyses.

Forum discussion | fcFEM repository (LGPL 2).

Topology optimization has long been a feature desired for those working with FEM. In 2016 the BESO (Bi-directional Evolutionary Structural Optimization) project was started, implementing an iterative method with the CalculiX solver that removes ineffective elements from a mesh in order to optimize the mass of the design. In the 0.19 development cycle, a simple graphical interface has been developed to facilitate generating the beso configuration files.

Forum discussion | beso repository (LGPL 3).

Similar to beso, the ToOptix project also provides a macro to perform topology optimization; it currently only works in structural and heat transfer studies.

Forum discussion (just a mention) | ToOptixFreeCADAddon repository (GPL 2).

Altro

  • Updated coding standards that strive for PEP8 compliance with Python; forum discussion, commit ad03ee9bdf, commit 27cb54009b.
  • The Elmer project has developed a library for handling batch type pre-processing for the ElmerSolver, using the FEM Workbench. This includes creating mesh objects for FreeCAD, manipulating the mesh sizes of solids, creating finite element meshes using Gmsh, running ElmerGrid and exporting the mesh for ElmerSolver, and selecting and naming bodies and boundaries for ElmerSolver; forum discussion, elmerfem repository (Elmer main repository), FreeCADBatchFEMTools repository (library to interact with FEM Workbench, LGPL 2.1).
  • The integration of the OOFem solver, which started in 2018, is progressing, so it is now another option that can be used for structural analysis in FreeCAD. This solver is interesting in that it has interface elements, as well as arc-length control, in addition to many non-linear material models. The integration of OOFEM into FEM has been carried in various commits that together serve as documentation on how to integrate similar solvers; forum discussion, femoofem branch, OOFEM main website, oofem repository (LGPL 2.1).

Mesh

Ambiente Part

New command Part PointsFromMesh to create an object made of points from an imported mesh. Then the points can be used as reference objects to do further operations, such as define a plane, and draw a sketch. This can be used to reverse engineer or remodel meshes by creating solid objects.

Forum discussion (and video), pull request #2450.

A script is provided in Mod/Part/parttests/part_test_objects.py, that produces a test file with the Part Primitives. This file is useful to learn scripting in Part, and can also be used to test regressions in the underlying code of the objects.

Pull request #3078.

Further improvements

Ambiente PartDesign

Features that have an "Attachment" property now show when the attachment mode is "deactivated" by displaying a small overlay to the left of the icon in the tree view. Features that are attached to a plane or other reference don't display this overlay.

Forum discussion | Pull request #2272.

The dialogs to edit fillets, chamfers, thickness, and draft features were improved to allow selecting several sub-elements (edges and faces) at once.

Forum discussion | Pull request #3050, Animated GIF.

Ambiente Path

  • Tool manager support for multiple tool tables
  • PathPocket: Extensions (For milling open pockets).
  • ProfileEdges: Open Edges support.
  • First attempt of 4th-axis support: Contour, PathFaces, PathPocket, and Drilling

Altro

Ambiente Render

Added support for Blender's standalone "Cycles" renderer; commit 759067912f; FreeCAD-render repository. The Cycles standalone renderer usually needs to be compiled from source, as the binary is normally not provided by itself in a complete Blender distribution.

Besides this, the Render Workbench already has support for Pov-Ray, Luxrender and Appleseed.

Ambiente Sketcher

In the Sketcher's task panel, in the "Elements" section there is now a "Mode" filter to select "normal", "construction", "external", or "all" geometry. This is useful to perform an action with only one type of geometry. For example, one use case is selecting only the "construction" edges, and deleting them after being used.
New Sketcher ToggleActiveConstraint tool to temporarily deactivate a constraint without removing it entirely. This is helpful to test the movement of the sketch before fully constraining it.

Pull request #2283, commit 159b8e7bdf.

Ambiente Spreadsheet

The introduction of App Link also brought some improvements to the expressions capabilities of FreeCAD, which are visible in the property editor, and the Spreadsheet Workbench. These are described in Core-Changes and this forum thread.

  • A new expression syntax is introduced to unambiguously reference a property of the owner object, by omitting the object reference and starting with a leading dot (.), similar to Python relative import syntax. So instead of Cylinder.Height, now you can use .Height.
  • You can refer to an object by its Name or by its Label. In the case of a Label, it must be enclosed in << and >> symbols, such as <<Label>>. For example, <<Metal_cylinder>>.Height.
  • Improved spreadsheet recomputation logic, and cell copy and paste functions.
  • Pull request #2350, #2475.

The previous commits changed the way the autocompletion works with expressions, particularly when used with Sketcher constraints, which was seen as a regression for many use cases. A new set of commits were proposed to restore this functionality; forum discussion, pull request #3062.

Ambiente Start

Re-added example files to the Start page with saved thumbnails in their icons.

Forum discussion, pull request #2316.

Ambiente Surface

None

Ambiente TechDraw

Improved placing and scaling of a 3D viewport screenshot in a TechDraw page.

Forum discussion.

New TechDraw Balloon tool to add balloon decorators to create notes with numbers, letters, and text.

Forum discussion, pull request #2013.

New TechDraw LeaderLine and TechDraw RichTextAnnotation tools to create better annotations in the drawing page.

Forum discussion, commit 7f07195f93, commit 6c699887c0; testing and bug fixing commit ab986d9a00, commit 15f440525e, commit 8ef3f13fbb, commit bf38ae958f, commit 74737f71fd, commit be257182ba, commit de3715908e, commit 916fe7ced3.

New TechDraw CosmeticVertex, TechDraw Midpoints, and TechDraw Quadrant tools, which allow the user to place fake or "cosmetic" vertices that can be used to create dimensions. The midpoint and quadrant vertices can be used to add more points to straight and curved edges (circular arcs), respectively; the "CosmeticVertex" tool can add a point anywhere on the drawing view without requiring being based on existing geometry.

Forum discussion, commit 59e47de506, commit 94b167f3a2.

New TechDraw FaceCenterLine, TechDraw 2LineCenterLine, and TechDraw 2PointCenterLine tools, to add a line in the center of a face, or between two existing edges, or between two existing points, respectively.

Also, TechDraw DecorateLine to change the appearance of single edges, and TechDraw CosmeticEraser to remove any of the cosmetic features from the view.

Forum discussion (v1, alpha), forum discussion (v2), commit 656e1654ff, commit 93431edfba, commit f25826bba3, commit 11d8aaed61, commit 941968b37c.

New TechDraw WeldSymbol tool to provide welding symbols. One of the most requested features from the older Drawing Workbench is finally in TechDraw. Russian standard (GOST) symbols are also added.

Forum discussion (testing), forum discussion (main thread); pull request #2446, #3110.

Old welding symbols from Drawing Workbench.

New TechDraw ActiveView tool. It produces a static image from the active 3D view, and puts it in a new TechDraw view. The result is a snapshot that doesn't update with changes to the model, and which is very fast to produce because it doesn't perform hidden line removal calculations. It is intended for rapid visualization of models, or to display flat projections of models without needing to add dimensions, a workflow that may be interesting for architectural visualization. Together with Arch SectionPlane and TechDraw NewArch, TechDraw ActiveView hopes to improve the interaction between Arch and TechDraw to document building models.

Only LGPL2 compatible code can be provided directly with TechDraw; code contributed under GPL2 or GPL3 needs to be stored in a separate repository.

The drawing of dimensions was completely rewritten. Now any drawn dimension is fully compliant with one of ISO 129-1 or ASME Y14.5M standards. There are four styles to choose from: ISO oriented (rotated value), ISO Referencing (horizontal value), ASME Inlined (horizontal value), ASME Referencing (value connected by a reference line).

Moduli aggiuntivi

Note: these are the new workbenches created in this development cycle, or older workbenches that received updates. See external workbenches for more workbenches that can be installed, and which cover a wide variety of topics. If you want to see your workbench added, join the forum and present your code.

3D Printing Tools

Previously it was called "MeshTools". It has utilities for working with imported STL meshes which could be used for 3D printing, like scaling the mesh up and down, scale it to fit a 3D printer, make objects transparent, hide and show objects, change colors and line widths of groups of objects, and others.

Forum discussion | 3D Printing Tools repository (LGPL 2.1).

A2plus

The successor to the Assembly2 workbench, A2plus is the most mature assembly workbench, and has received important updates in this development cycle, like an improved point on plane constraint, and point on line constraint, using the center of a sphere as the point; this improves the constraining of spheres.

Forum discussion | A2plus repository (LGPL 2.1).

Please note: A2plus is not compatible with Assembly2 or other assembly workbenches. If you have previous assemblies, they will need to be re-created entirely in A2plus.

Assembly3

Assembly3 is an assembly workbench created by developer realthunder, that is inspired by Assembly2, but is not compatible with it. Assembly3 makes use of realthunder's App Link object and various significant changes to the internal code of FreeCAD. Because of this reason, Assembly3 cannot be installed simply from the Addon Manager. Instead, realthunder provides a pre-compiled version of FreeCAD that includes Assembly3. This workbench serves as a testing environment for the App Link object, and other changes that realthunder plans to submit to the main FreeCAD source code.

The Assembly3 workbench can also be tested in the development AppImage.

Forum discussion (massive thread) | FreeCAD_assembly3 repository (GPL 3).

Assembly4 is an assembly workbench created by developer Zolko, that uses realthunder's App Link object and many other changes to the base FreeCAD system, particularly the new expression engine. Because of this, Assembly4 doesn't work with versions below 0.19. Assembly4 can be installed from the Addon Manager.

Unlike A2plus and Assembly3, Assembly4 tries to perform assembly without using a constraint solver, but rather with the concept of arranging local coordinate systems (LCS) and setting relationships through mathematical expressions.

ArchTextures

The ArchTextures Workbench was developed to provide basic texture support to Arch Workbench elements like walls and roofs, in order to quickly visualize a building. It is not intended to produce photo-realistic renderings, just simple texturing of materials like wood, brick, and concrete. It also provides lights (directional, point, and spot), which makes it more feature complete to set up a scene.

BOLTSFC

BOLTS is an "open library of technical specifications"; it is meant to provide free, standardized parts defined parametrically that can be used in different CAD systems like OpenSCAD and FreeCAD. The BOLTS library was launched in 2013 but received little maintenance since 2016. Now, with a new maintainer and repository, the project has revived with the BOLTSFC workbench that provides an interface to insert the different parametric objects.

CurvedShapes Workbench

The CurvedShapes workbench has tools for designing 3D surfaces starting from a skeleton of multiple curves in the XY, XZ, or YZ planes. It was created particularly to simplify the modelling of the wings of aircrafts.

Dodo (formerly Flamingo)

Dodo is the successor to the Flamingo Workbench, a workbench specialized in creating piping and frames. While Flamingo was developed for Python 2 and Qt4, Dodo is meant to work with Python 3 and Qt5. It provides the same features as Flamingo, but has improved tools and interfaces.

Fasteners

The Fasteners Workbench to generate standard ISO screws, bolts, washers, and other fasteners, was updated to work with Python 3 and Qt5.

Geomatics Workbench

A workbench that provides functionality specific to Geomatics and Survey engineering, such as importing geodata information, and creating surfaces from clouds of points. There are some issues with rendering objects that use large coordinates (kilometers) and importing large DXF files. If you want to help solving these issues, please contact the developers.

MeshRemodel Workbench

This workbench helps convert a mesh, for example, an imported STL file, into a native FreeCAD object. It will not do the conversion automatically, but it will help re-build, or re-model, the imported mesh. The general workflow is to select the mesh object, then create a "points" object from it; then these points can be used as references for creating FreeCAD objects such as lines, polygons, circles, arcs, and BSplines. These wires can then be turned into a Sketch object, which can be padded to create a 3D solid with the PartDesign Workbench.

MOOC Workbench

The MOOC workbench is an educational tool that offers interactive tutorials and exercise evaluations to learn to use FreeCAD. It was developed as part of a series of courses on Digital Manufacturing.

At this moment, the workbench is only offered in the French language.

NodeEditor (PyFlow)

The NodeEditor workbench implements a system of nodes that can be used to dynamically control the properties of objects, similar to Blender's node system to edit materials. The NodeEditor is based on a slightly modified version of the PyFlow framework, which is under active development.

A node editor has been a requested feature for a very long time, at least since 2014 (see this thread). A fully working node editor has the potential of simplifying the drawing of complex shapes using generative algorithms that produce a shape based on the values of its inputs. This could be used to create various types of meshes and surfaces with applications in architecture and mechanical design.

Trails, PyTrails, Turns, and pivy_trackers

The Trails workbench was formerly known as the "Transportation Engineering" workbench. It consists of a toolset for developing highway and railway designs, including horizontal alignments, vertical profiles, and 3D models.

Forum discussion (original thread that started the project), forum discussion (main thread, very long), video example | freecad.trails repository (LGPL 2.1).

Most of the functions used in the Trails workbench have been placed in a new Python library called PyTrails. The expectation is that Trails serves as a FreeCAD based graphical interface for PyTrails, while PyTrails remains a general purpose library that can be used outside FreeCAD in other projects.

Forum discussion (PyTrails announcement) | PyTrails repository (LGPL 2.1).

The Turns workbench is a small component that was created during development of the Trails workbench. It performs vehicle swept-path analysis (turning analysis) for highway intersections and other entrances.

Forum discussion (main thread) | freecad.turns repository (LGPL 2.1), animated GIF.

After working with Trails and Turns, the author decided to split the tracker code into a separate library called pivy_trackers. This is a general library that could be included in other workbenches to generate tracker objects and perform actions in the scene, like dragging lines, dragging points, and changing certain geometrical elements on the fly.
