PartDesign Workbenchは、複雑なソリッドパーツをモデリングする高度なツールを提供します。 これは主に、完成品に製造して組み立てることができる機械部品の製造に重点を置いています。 それにもかかわらず、作成されたソリッドは、architectural design, FE analysis、3D印刷などの一般的な目的に使用できます。



  • パッド スケッチの押し出しを行います
  • ポケット 既存のソリッドにポケット(くぼみ)を作成します
  • 回転 軸の周りにスケッチを回転させてソリッドを作成します
  • 既存のソリッドに溝を作成します


パートデザインワークベンチで非常に重要となるコンセプトはスケッチのサポート(支持物)です。スケッチは標準面(XYXZYZとそれらに平行な面)上または既存のソリッドの面上に作成することができます。後者の場合、既存のソリッドがスケッチのサポートとなります。ツールの中にはサポートを持っているスケッチに対してだけ使用できるものがいくつかあります。例えばポケットです - サポートがない場合、マテリアルからは何も取り除かれません!



While the Workbench Part.svg 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.

Structure tools

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.

  • Std Part.svg Part: adds a new Part container in the active document and makes it active.
  • Std Group.svg 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 MapSketch.svg 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.

  • 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.

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.

Transformation tools

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

  • PartDesign Mirrored.svg Mirrored: mirrors one or more features on a plane or face.
  • PartDesign LinearPattern.svg 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.

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


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

Template:PartDesign Placement/jp

Some additional functionality found in the Part Design menu:

  • PartDesign Migrate.svg 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.
  • PartDesign WizardShaft.svg 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

  • PartDesign MoveTip.svg Set tip: redefines the tip, which is the feature exposed outside of the Body.
  • PartDesign MoveFeatureInTree.svg 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

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


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