PartDesign Workbench/ja

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.



はじめに
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.

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. 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

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.



ツール
パートデザインツールは全てパートデザインを読み込んだ時点で表示されるPart Designメニューにあります.

ここにはスケッチャーワークベンチのツールも含まれています. これはパートデザインモジュールがそれらと深く関係しているからです.

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.

Part Design Helper tools

 * PartDesign Body.png Create body: Creates a Body in the active document and makes it active.


 * PartDesign_NewSketch.png 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.


 * [[Image:Sketcher_EditSketch.png|32px]] Edit sketch: Edit the selected Sketch.

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


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


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


 * PartDesign AdditiveLoft.png Additive loft: creates a solid by making a transition between two or more sketches.


 * PartDesign AdditivePipe.png 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.


 * PartDesign AdditiveBox.png Additive box: creates an additive box.


 * PartDesign AdditiveCone.png Additive cone: creates an additive cone.


 * PartDesign AdditiveCylinder.png Additive cylinder: creates an additive cylinder.


 * PartDesign AdditiveEllipsoid.png Additive ellipsoid: creates an additive ellipsoid.


 * PartDesign AdditivePrism.png Additive prism: creates an additive prism.


 * PartDesign AdditiveSphere.png Additive sphere: creates an additive sphere.


 * PartDesign AdditiveTorus.png Additive torus: creates an additive torus.


 * PartDesign AdditiveWedge.png Additive wedge: creates an additive wedge.

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


 * PartDesign Pocket.png Pocket: creates a pocket from a selected sketch.


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


 * PartDesign Groove.png Groove: creates a groove by revolving a sketch around an axis.


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


 * PartDesign SubtractivePipe.png 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.

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

フィーチャープロパティ
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.


 * [[Image:PartDesign_WizardShaft.png|32px]] 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.


 * [[Image:PartDesign_InternalExternalGear.png|32px]] Involute gear: creates an involute gear profile that can be used by a Pad.

Contextual Menu tools

 * PartDesign MoveTip.png 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.
