=== Feature Editing Methodology ===

While the [[Part Workbench]] and other FreeCAD workbenches construct models by combining shapes together, the PartDesign workbench uses '''features'''. A [https://en.wikipedia.org/wiki/Feature_recognition feature] is an operation that modifies the shape of a model.

The first feature is commonly called the '''base feature'''. As more features are added to the model, each feature takes the shape of the previous one and adds or removes matter, creating linear dependencies from one feature to the next. In effect, this methodology mimics a common manufacturing process: a block is cut on one side, then on another side, holes are added, then rounds, etc.

All features are listed sequentially in the Model tree and can be edited at any time, with the last feature at the bottom representing the final part.

Features can be sorted into different categories:

* '''Profile-based''': these features start from a profile to define the shape of the matter to be added or removed. The profile can be a sketch, a planar face on existing geometry (a profile will be extracted from its edges), a ShapeBinder or a Draft object that has been included in the active Body.

* '''Additive''': adds matter to the existing model. Additive features show yellow icons.

* '''Subtractive''': removes matter from the existing model. Subtractive features show red and blue icons.

* '''Primitive-based''': based on geometric primitives (cube, cylinder, cone, torus…). They can be additive or subtractive.

* '''Transformation features''': they apply a transformation to existing features (mirrored, linear pattern, polar pattern, multitransform).


The PartDesign Workbench is intrinsically related to the [[Sketcher Workbench|Sketcher Workbench]]. The user normally creates a Sketch, then uses the [[PartDesign_Pad|PartDesign Pad]] tool to extrude it and create a basic solid, and then this solid is further modified.
* '''Dress-up''': features that apply a treatment to edges or faces, such as fillets/rounds, chamfers and drafts.


While the [[Image:Workbench_Part.svg|24px]] [[Part Module|Part Workbench]] is based on a [[constructive_solid_geometry|constructive solid geometry]] (CSG) methodology for building shapes, the PartDesign Workbench uses a parametric, feature editing methodology, which means a basic solid is sequentially transformed by adding features on top until the final shape is obtained. See the [[feature_editing|feature editing]] page for a more complete explanation of this process, and then see [[Creating_a_simple_part_with_PartDesign|Creating a simple part with PartDesign]] to get started with creating solids.
* '''Procedural''': can be said of features that are not based on sketches, like the transformation and dress-up features.


A more detailed discussion of Part workbench versus Part Design workbench can be found here: [[Part_and_Part_Design| Part and Part Design]].
=== Body ===


The bodies created with PartDesign are often subject to the [[Topological_naming_problem|topological naming problem]] which causes internal features to be renamed when the parametric operations are modified. This problem can be minimized by following the best practices described in the [[feature_editing|feature editing]] page, and by taking advantage of datum objects as support for sketches and features.
The Body is a container that groups a sequence of features forming a single contiguous solid.


[[Image:PartDesign Example.png|none|500px]]
What is a single contiguous solid? It is an object like a casting or something machined from a single block of metal. If the object involves nails, screws, glue or welding, it is not a single contiguous solid. As a practical example, a wooden chair would be made of multiple bodies, with one for each of its sub-components (legs, slats, seat, etc).

=== Structure tools ===
[[Category:User Documentation/id]]
</div>


These are tools to organize the Model tree.
==== Body Visibility Management ====


* [[Image:Std_Part.png|32px]] [[Std Part|Part]]: adds a new Part container in the active document and makes it active.
A body will present by default its most recent feature to the outside. This feature is defined by default as the tip. A good analogy is the expression ''the tip of the iceberg'': only the tip is visible above the water, most of the iceberg's mass (the other features) is hidden. As a new feature is added to the body, visibility of the previous feature is turned off, and the new feature becomes the tip.
* [[Image:Group.svg|32px]] [[Std Group|Group]]: adds a Group in the active document's Model tree.
</div>


These tools are in fact not part of the PartDesign Workbench. They belong to the [[Std_Base|Std Base]] system. They were developed in v0.17 with the intention that they would be useful to organize a model, and create [[Assembly|assemblies]]; as such, they are very useful when working with bodies created with this workbench.
There can only be one feature visible at a time. It is possible to toggle the visibility of any feature in the body, by selecting it in the Model tree and pressing the spacebar, in effect going back in the history of the body.


* [[Image:Std_Part.svg|32px]] [[Std_Part|Part]]: adds a new Part container in the active document and makes it active.
==== Body Origin ====


* [[Image:Std_Group.svg|32px]] [[Std_Group|Group]]: adds a Group container in the active document, which allows organizing the objects in the [[Tree_view|tree view]].
The body has an Origin which consists of reference planes (XY, XZ, YZ) and axes (X, Y, Z) that can be used by sketches and features. Sketches can be attached to Origin planes, and they no longer need to be mapped to planar faces for features based on them to be added or subtracted from the model.


==== Moving and Reordering Objects ====
=== Part Design Helper tools ===


*[[File:PartDesign_Body.svg|32px]] [[PartDesign_Body|Create body]]: creates a [[Body|Body]] object in the active document and makes it active.
It is possible to temporarily redefine the tip to a feature in the middle of the Body tree to insert new objects (features, sketches or datum geometry). It is also possible to reorder features under a Body, or to move them to a different Body. Select the object and right-click to get a contextual menu that will offer both options. The operation may be prevented if the object has dependencies in the source Body, such as being attached to a face. To move a sketch to another Body, it should not contain links to external geometry.


*[[File:Sketcher_NewSketch.svg|32px]] [[PartDesign_NewSketch|Create sketch]]: creates‎ a new sketch on a selected face or plane. If no face is selected while this tool is executed, the user is prompted to select a plane from the Tasks panel. The interface then switches to the [[Sketcher_Workbench|Sketcher Workbench]] in sketch editing mode.
=== Datum Geometry ===


* [[File:Sketcher_EditSketch.svg|32px]] [[Sketcher_EditSketch|Edit sketch]]: Edit the selected Sketch.
Datum geometry consists of custom planes, lines, points or externally linked shapes. They can be created for use as reference by sketches and features. There is a multitude of attachment possibilities for datums.


* [[File:Sketcher_MapSketch.svg|32px]] [[Sketcher_MapSketch|Map sketch to face]]: Maps a sketch to a previously selected plane or a face of the active body.
=== Cross-referencing ===


=== Part Design Modeling tools ===
It is possible to cross-reference elements from a body in another body via datums. For example the datum shape binder allows to copy over faces from a body as reference in another one. This should make it easy to build a box with fitting cover in two different bodies. FreeCAD helps you to not accidentally link to other bodies and queries your intent.


=== Attachment ===
==== Datum tools ====


*[[File:PartDesign_Point.svg|32px]] [[PartDesign_Point|Create a datum point]]: creates a datum point in the active body.
Object attachment is not a specific PartDesign tool, but rather a Part utility introduced in v0.17 that can be found in the Part menu. It is heavily used in the PartDesign workbench to attach sketches and reference geometry to the standard planes and axes of the Body. Very extensive ways of creating datum points, lines and planes are available. Optional attachment offset parameters make this tool very versatile.


*[[File:PartDesign_Line.svg|32px]] [[PartDesign_Line|Create a datum line]]: creates a datum line in the active body.
More info can be found in the [[Part Attachment|Attachment]] page.


*[[File:PartDesign_Plane.svg|32px]] [[PartDesign_Plane|Create a datum plane]]: creates a datum plane in the active body.
=== Advice for creating stable models ===


*[[File:PartDesign_CoordinateSystem.svg|32px]] [[PartDesign_CoordinateSystem|Create a local coordinate system]]: creates a local coordinate system attached to datum geometry in the active body.
The idea of parametric modeling implies that you can change the values of certain parameters and subsequent steps are changed according to the new values. However, when severe changes are made, the model can break. Compared to previous FreeCAD versions breaking can be minimized when you respect the following design principles:


*[[File:PartDesign_ShapeBinder.svg|32px]] [[PartDesign_ShapeBinder|Create a shape binder]]: creates a shape binder in the active body.
* Basically, you need to stop mapping sketches to faces - entirely! Place your sketches on standard planes, or on custom datum planes.
* When creating datum geometry, do not base it on the part topology, base it on standard planes/axes and/or sketches.
* Use a "master sketch". That is a preferably not too complicated sketch which contains basic geometric elements of your model. These elements can be referenced when modeling subsequent features. Such a master sketch will often be the first sketch in the Body but it doesn't have to be; in fact you don't even have to use it at all for anything else but being referenced.
* If you inevitably have to reference an intermediate feature, e.g. the result of a thickness operation, use the first reference possible in the list of subsequent features where the referenced geometric element occurs. From FreeCAD 0.17 on you don't have to use the latest feature. If you take an early feature as reference, all changes to intermediate steps won't break your model. And again it is better to reference a sketch than edges and vertices of a solid


*[[File:PartDesign_SubShapeBinder.svg|32px]] [[PartDesign_SubShapeBinder|Create a sub-object shape binder]]: creates a shape binder to a subelement, like edge or face from another body, while retaining the relative position of that element. {{Version|0.19}}
== The Tools ==


*[[File:PartDesign_Clone.svg|32px]] [[PartDesign_Clone|Create a clone]]: creates a clone of the selected body.
The Part Design tools are all located in the '''Part Design''' menu and the PartDesign toolbar that appear when you load the Part Design workbench.

Introduction

The PartDesign Workbench is intrinsically related to the Sketcher Workbench. The user normally creates a Sketch, then uses the PartDesign Pad tool to extrude it and create a basic solid, and then this solid is further modified.

While the Part Workbench is based on a constructive solid geometry (CSG) methodology for building shapes, the PartDesign Workbench uses a parametric, feature editing methodology, which means a basic solid is sequentially transformed by adding features on top until the final shape is obtained. See the feature editing page for a more complete explanation of this process, and then see Creating a simple part with PartDesign to get started with creating solids.

A more detailed discussion of Part workbench versus Part Design workbench can be found here: Part and Part Design.

The bodies created with PartDesign are often subject to the topological naming problem which causes internal features to be renamed when the parametric operations are modified. This problem can be minimized by following the best practices described in the feature editing page, and by taking advantage of datum objects as support for sketches and features.

Tools

The Part Design tools are all located in the Part Design menu and the PartDesign toolbar that appear when you load the Part Design workbench.

Structure tools

These are tools to organize the Model tree.

  • Part: adds a new Part container in the active document and makes it active.
  • Group: adds a Group in the active document's Model tree.

These tools are in fact not part of the PartDesign Workbench. They belong to the Std Base system. They were developed in v0.17 with the intention that they would be useful to organize a model, and create assemblies; as such, they are very useful when working with bodies created with this workbench.

  • Part: adds a new Part container in the active document and makes it active.
  • Group: adds a Group container in the active document, which allows organizing the objects in the tree view.

Part Design Helper tools

  • Create body: creates a Body object in the active document and makes it active.
  • Create sketch: creates‎ a new sketch on a selected face or plane. If no face is selected while this tool is executed, the user is prompted to select a plane from the Tasks panel. The interface then switches to the Sketcher Workbench in sketch editing mode.
  • Map sketch to face: Maps a sketch to a previously selected plane or a face of the active body.

Part Design Modeling tools

Datum tools

Additive tools

These are tools for creating base features or adding material to an existing solid body.

  • Pad: extrudes a solid from a selected sketch.
  • Revolution: creates a solid by revolving a sketch around an axis. The sketch must form a closed profile.
  • Additive loft: creates a solid by making a transition between two or more sketches.
  • Additive pipe: creates a solid by sweeping one or more sketches along an open or closed path.

Subtractive tools

These are tools for subtracting material from an existing body.

  • Pocket: creates a pocket from a selected sketch.
  • Hole: creates a hole feature from a selected sketch. The sketch must contain one or multiple circles.
  • Groove: creates a groove by revolving a sketch around an axis.
  • Subtractive loft: creates a solid shape by making a transition between two or more sketches and subtracts it from the active body.
  • Subtractive pipe: creates a solid shape by sweeping one or more sketches along an open or closed path and subtracts it from the active body.

Transformation tools

These are tools for transforming existing features. They will allow you to choose which features to transform.

  • Mirrored: mirrors one or more features on a plane or face.
  • Linear Pattern: creates a linear pattern based on one or more features.

Dress-up tools

These tools apply a treatment to the selected edges or faces.

  • Fillet: fillets (rounds) edges of the active body.
  • Chamfer: chamfers edges of the active body.
  • Draft: applies an angular draft to selected faces of the active body.
  • Thickness: creates a thick shell from the active body and opens selected face(s).

Boolean

  • Boolean operation: imports one or more Bodies or PartDesign Clones into the active body and applies a Boolean operation.

Extras

Some additional functionality found in the Part Design menu:

  • Migrate: migrates files created with older FreeCAD versions. If the file is pure PartDesign feature-based, migration should succeed. If the file contains mixed Part/Part Design/Draft objects, the conversion will most likely fail.
  • Shaft design wizard: Generates a shaft from a table of values and allows to analyze forces and moments. The shaft is made with a revolved sketch that can be edited.

Context Menu items

  • Set tip: redefines the tip, which is the feature exposed outside of the Body.
  • Move object after other object: allows reordering of the Body tree by moving the selected sketch, datum geometry or feature to another position in the list of features.

Items shared with the Part workbench

  • Appearance: determines appearance of the whole part (color transparency etc.).

Preferences

  • Preferences: preferences available for PartDesign Tools.
  • Fine tuning: some extra parameters to fine-tune PartDesign behavior.
