Benutzeroberfläche

Navi Cube relnotes 0.20.gif Der Navigationswürfel wurde überarbeitet, um diese neuen Funktionen zu ermöglichen:
  • Es gibt jetzt Kantenflächen, um die Szene in Winkeln von 45° zu betrachten.
  • Die neue Voreinstellungsoption Nächste Drehung erlaubt es, die Szene in der nächstgelegenen sinnvollen Position zu betrachten. Wenn sie ausgeschaltet ist, wird das Anklicken einer Würfelfläche immer an der gleichen Position angezeigt, unabhängig davon, in welchem Würfelzustand du dich befandest, als du die Fläche angeklickt hast. Klicke auf das Bild auf der linken Seite, um zu sehen, was das bedeutet. Versuche die gleiche Klicksequenz wie im Bild ohne die Option Drehen zum nächstgelegenen, um den Unterschied zu erleben.
  • Wenn du auf den Punkt oben rechts im Würfel klickst, kannst du schnell die Rückansicht der aktuellen Szene sehen.
  • Die Größe des Würfels kann über die Einstellungsoption Würfelgröße angepasst werden.

Forumsdiskussion, pull request #4502 .

Improved tooltips relnotes 0.20.gif Tooltips now display the command name in the title, making it easier for new users to look for help. At the end of the tooltip the "internal" command name is added in parentheses: (Std_WhatsThis). This is also the name of the page that documents the command in the Wiki. Forum discussion, Pull request #4978 .
Std UserEditMode relnotes 0.20.gif The new Std UserEditMode command allows the user to choose an edit mode that will be used when an object is double-clicked in the Tree view. Click the image at the left so see an animation of the selection. If a selected edit mode is not applicable, the object's default edit mode is used instead. Pull request #5110.
Dependencies-selection relnotes 0.20.png The Tree view context menu has the new entry Add dependent objects to selection.
Forum discussion, Pull request #4133.

In the image the Hole001 object was selected and then its
dependencies were added to the selection via the context menu.

Part SectionCut example relnotes 0.20.png The new tool Section Cut allows to get non-hollow and also persistent cuts of parts and assemblies.

Object selection relnotes 0.20.png When using Edit → Copy or Edit → Duplicate selection for an object with dependencies there is a new Use Original Selections button in the object selection dialog. Click this button to copy/duplicate only the objects you originally selected prior to opening the dialog, ignoring dependencies and ignoring any actions you might have taken while the dialog was open, such as checking or unchecking some of the checkboxes. The effect is the same as if you had unchecked all the checkboxes next to the objects you did not originally select and pressed OK. Note: special care should be taken when copying/duplicating TechDraw Pages. It is recommended to also copy/duplicate all of the children of the Page (Templates, Views, Dimensions, etc.). Otherwise changes to one of the Pages will also impact the other page, for example, deleting one of the Views in one Page also removes it from the other Page. Deleting one of the pages will also remove all the content from the other Page if copies of the content are not also made.
PrefPacks relnotes 0.20.png A new type of add-on called a Preference Pack was added, allowing a subset of a user preferences (user.cfg) file to be saved, distributed, and easily applied by other users. Preference Packs can be use to distribute "Themes," for example, by allowing a developer to include both a Qt stylesheet for widgets as well as a set of other colors and styles for items in the user interface that cannot be set using a stylesheet (e.g. text colors in the Python editor or report view, etc.). Anything that can be configured via a user.cfg file can be set using a Preference Pack. Forum discussion
Autoload relnotes 0.20.png The "Workbenches" preference panel was modified to support the ability to "autoload" workbenches on FreeCAD startup.

Erweiterungsverwalter

AddonManagerExpanded relnotes 0.20.png The Addon Manager was modified to support the distribution of Preference Packs, and to display information found in an addon's metadata. The Addon Manager also includes improved support for Addons whose source code is located at several different git hosting locations. Networking support was improved to provide more robust handling of SSL connections and support for proxies requiring authentication. Support was added for automatically adding macro buttons to the toolbar after installing, for disabling Addons without removing them, and for switching which git branch of an Addon is checked out. Finally, the user interface was modified to improve searching and display of different list filters.

Forum discussion

NewArchStructureProperties relnotes 0.20.jpg New properties in the Arch Structure objects

BasePerpendicularToTool: it copies the Base (extrusion profile) at the beginning of the Tool (extrusion path) and places it perpendicular to the first edge of the tool. It is the same as attaching the Base with MapMode=NormalToEdge, but its automatic and allows to reuse the same Base object for multiple Structures. When BasePerpendicularToTool = True, more properties control the placement of the Base relative to the Tool axis. They are shown in the attached image.

ToolOffsetFirst and ToolOffsetLast: extend/trim the Structure at the start and end respectively (the real length of the Structure is available in the ComputedLength readonly property)

  • BaseRotation: rotate the Base (the rotation is around the Base's "(0,0)" point which is the center for Arch Profiles, the origin for Sketches and usually the first point for Draft Wires)
  • BaseOffsetX and BaseOffsetY: move the Base (extrusion profile)
  • BaseMirror: mirror the Base (extrusion profile)

A new command Create multiple Arch Structure was also added. It uses the first selected object as a Base, and creates Arch Structures objects for every Edge of the other selected objects. Then, the properties of individual Structure objects can be adjusted in the Property editor. This command was added for workflow with a master Sketch (there is risk of topological naming problem unless you create non-parametric copy of the master Sketch or use Realthunder's version)

Forum discussion, Pull request #3229

Arbeitsbereich Entwurf

  • A Global checkbox was added to the task panel of many drafting commands. Checking it allows input of coordinates in the global coordinate system even if the working plane is not aligned with the global XY plane.
  • The Draft Hatch.svg Draft Hatch command was introduced. It creates hatches on the faces of a selected object using patterns from AutoCAD PAT files.
  • Work on the Draft SetStyle.svg Draft SetStyle command, still in progress in FreeCAD version 0.19, was completed.
  • A double-click edit option was added for Draft Text.svg Draft Texts. It opens the same edit task panel used when creating a text.
  • For Draft Dimension.svg Draft Dimensions the arch AnsichtUnit Override for imperial architectural dimensions was introduced.
  • Draft Shape2DView.svg Draft Shape2DView objects now have an DatenAuto Update property. Setting it to false can be useful if there are many Draft Shape2DViews in a document or if they are complex.

Fixed false negatives during self-intersection tests when facets are coplanar: Pull request #5002.

OpenSCAD Arbeitsbereich

Interoperability with OpenSCAD has been improved, adding support for several operations missing from earlier versions (linear extrude with rotations, rotational extrusions). Several operations are modified to provide improved FreeCAD object equivalents, particularly for twisted extrusions. Surface generation from discrete data was modified to give more OpenSCAD-like results, rather than splined surfaces.

New options were added to support running either FreeCAD, OpenSCAD, or both, in sandboxed environments such as AppImages and Snap packages: data can now be transferred to and from OpenSCAD via the standard temporary directory mechanism, via a user-specified temp directory that both executables have access to, or new to OpenSCAD 2021.1, via a "stdout pipe" mechanism, bypassing temporary files entirely.

Add OpenSCAD element - now has additional options

Load    - load a scad file
Save    - save a scad file
Refresh - Update FreeCAD view
Clear   - Clear text input

There is also a text box for feedback of OpenSCAD errors.

PartDesign Loft Vertex relnotes 0.20.png
A loft with multiple sections, the final one is a vertex.
It is now possible to create an Additive or Subtractive Loft, or an Additive or Subtractive Pipe towards, or from, a Vertex of either a sketch or a body. This allows to create pyramids for example.
Note: Vertices in sketches are created as construction geometry. To use them as endpoints of lofts, you must first change them to normal geometry.

PartDesign Islands-Extrude relnotes 0.20.png
A single Pad and a single Revolution with nested profiles. The base block is only there to ensure that the part is a single solid.
All PartDesign features that can extrude sketches can now handle sketches with nested profiles that form islands. For example it is possible to revolve a sketch consisting of 3 nested circles with the same center point.
Note: Extruding nested profiles only works if the result is still a single body.
