はじめに
パートデザインツールは複雑なソリッド部品のモデリングのためのツールを提供することを目的とし、フィーチャー編集による方法をその基盤としています。パートデザインツールはスケッチャーワークベンチと複雑に関係しています。
基本的な作業の流れ
スケッチとはソリッド部品を作成、編集するための基本となる要素のことです。作業の流れを要約するとこうなります:まず最初に2D形状を含むスケッチを作成します。次にスケッチに対してソリッド作成ツールを使用します。この時に利用可能なツールは以下の通りです。
- 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
- 溝 既存のソリッドに溝を作成します
将来のリリースではさらなるツールが計画されています。
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(XY、XZ、YZ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!
いったんソリッド形状が作成されれば面取りやフィレットといった変更やミラーやパターンといった変形を行うことができるようになります。
パートデザインワークベンチは一つのつながったソリッドを作るためのものです。複数のソリッドはアセンブリワークベンチで取り扱うことができます。
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.

パートデザインツール
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.
Part Design Helper tools
- Create body: Creates a Body 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.
- Edit sketch: Edit the selected Sketch.
- 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
- Create a datum point: creates a datum point in the active body.
- Create a datum line: creates a datum line in the active body.
- Create a datum plane: creates a datum plane in the active body.
- Create a shape binder: creates a shape binder in the active body.
- Create a clone: creates a clone of the selected body.

フィーチャープロパティ
Template:PartDesign Placement/jp
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.
- Create an additive primitive: adds an additive primitive to the active body.
- Additive box: creates an additive box.
- Additive cone: creates an additive cone.
- Additive cylinder: creates an additive cylinder.
- Additive ellipsoid: creates an additive ellipsoid.
- Additive prism: creates an additive prism.
- Additive sphere: creates an additive sphere.
- Additive torus: creates an additive torus.
- Additive wedge: creates an additive wedge.
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.
- Create a subtractive primitive: adds a subtractive primitive to the active body.
- Subtractive box: adds a subtractive box to the active body.
- Subtractive cone: adds a subtractive cone to the active body.
- Subtractive cylinder: adds a subtractive cylinder to the active body.
- Subtractive ellipsoid: adds a subtractive ellipsoid to the active body.
- Subtractive prism: adds a subtractive prism to the active body.
- Subtractive sphere: adds a subtractive sphere to the active body.
- Subtractive torus: adds a subtractive torus to the active body.
- Subtractive wedge: adds a subtractive wedge to 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.
- Polar Pattern: creates a polar pattern of one or more features.
- Create MultiTransform: creates a pattern with any combination of the other transformations.
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 and angular draft to 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.
- Involute gear: creates an involute gear profile that can be used by a Pad.
Contextual Menu tools
- Set tip: redefines the tip, which is the feature exposed outside of the Body.
- Move object to other body: moves the selected sketch, datum geometry or feature to another 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.
