PartDesign Workbench/sv

Introduction
The PartDesign Workbench provides advanced tools for modeling complex solid parts. It is mostly focused on creating mechanical parts that can be manufactured and assembled into a finished product. Nevertheless, the created solids can be used in general for any other purpose such as architectural design, finite element analysis, or machining and 3D printing.

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.

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.



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

Structure tools
These are tools to organize the Model tree.


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


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


 * [[Image:Std_Group.svg|32px]] Group: adds a Group container in the active document, which allows organizing the objects in the tree view.

Part Design Helper tools

 * PartDesign_Body.svg Create body: creates a Body object in the active document and makes it active.


 * Sketcher_NewSketch.svg 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.


 * Sketcher_EditSketch.svg Edit sketch: Edit the selected Sketch.


 * Sketcher_MapSketch.svg Map sketch to face: Maps a sketch to a previously selected plane or a face of the active body.

Datum tools

 * PartDesign_Plane.svg Create a datum plane: creates a datum plane in the active body.


 * PartDesign_CoordinateSystem.svg Create a local coordinate system: creates a local coordinate system attached to datum geometry in the active body.


 * PartDesign_ShapeBinder.svg Create a shape binder: creates a shape binder in the active body.


 * PartDesign_SubShapeBinder.svg 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.


 * PartDesign_Clone.svg Create a clone: creates a clone of the selected body.

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


 * PartDesign_Pad.svg Pad: extrudes a solid from a selected sketch.


 * PartDesign_Revolution.svg Revolution: creates a solid by revolving a sketch around an axis. The sketch must form a closed profile.


 * PartDesign_AdditiveLoft.svg Additive loft: creates a solid by making a transition between two or more sketches.


 * PartDesign_AdditivePipe.svg Additive pipe: creates a solid by sweeping one or more sketches along an open or closed path.


 * PartDesign_AdditiveHelix.svg Additive helix: creates a solid by sweeping a sketch along a helix.


 * PartDesign_CompPrimitiveAdditive.png Create an additive primitive: adds an additive primitive to the active body.


 * PartDesign_AdditiveBox.svg Additive box: creates an additive box.


 * PartDesign_AdditiveCone.svg Additive cone: creates an additive cone.


 * PartDesign_AdditiveCylinder.svg Additive cylinder: creates an additive cylinder.


 * PartDesign_AdditiveEllipsoid.svg Additive ellipsoid: creates an additive ellipsoid.


 * PartDesign_AdditivePrism.svg Additive prism: creates an additive prism.


 * PartDesign_AdditiveSphere.svg Additive sphere: creates an additive sphere.


 * PartDesign_AdditiveTorus.svg Additive torus: creates an additive torus.


 * PartDesign_AdditiveWedge.svg Additive wedge: creates an additive wedge.

Subtractive tools
These are tools for subtracting material from an existing body.


 * PartDesign_Pocket.svg Pocket: creates a pocket from a selected sketch.


 * PartDesign_Hole.svg Hole: creates a hole feature from a selected sketch. The sketch must contain one or multiple circles.


 * PartDesign_Groove.svg Groove: creates a groove by revolving a sketch around an axis.


 * PartDesign_SubtractiveLoft.svg Subtractive loft: creates a solid shape by making a transition between two or more sketches and subtracts it from the active body.


 * PartDesign_SubtractivePipe.svg 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.


 * PartDesign_SubtractiveHelix.svg Subtractive helix: creates a solid shape by sweeping a sketch along a helix and subtracts it from the active body.


 * PartDesign_CompPrimitiveSubtractive.png Create a subtractive primitive: adds a subtractive primitive to the active body.

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

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

 * PartDesign_Boolean.svg 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:


 * [[Image:PartDesign_Migrate.svg|32px]] 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.
