Part objects are more complex than mesh objects created with the [[Mesh Workbench|Mesh Workbench]], as they permit more advanced operations like coherent boolean operations, modifications history, and parametric behaviour.

Part workbench icon

FreeCADのCAD機能はOpenCasCadeカーネルをその基礎としています。FreeCADはパートモジュールによってOpenCasCadeオブジェクトとその機能へのアクセス・利用を行なっています。OpenCascadeはプロフェッショナル用のCADカーネルでその機能は3D形状操作、3D形状オブジェクトに特化しています。メッシュモジュール のオブジェクトと異なりパートオブジェクトはより複雑で、明確なブーリアン演算、変更履歴、パラメトリックな動作などのより高度な処理が可能です。

The objects created with the Part Workbench are relatively simple; they are intended to be used with boolean operations (unions and cuts) in order to build more complex shapes. This modeling paradigm is known as the constructive solid geometry (CSG) workflow, and it was the traditional methodology used in early CAD systems. On the other hand, the PartDesign Workbench provides a more modern workflow to constructing shapes: it uses a parametrically defined sketch, that is extruded to form a basic solid body, which is then modified by parametric transformations (feature editing), until the final object is obtained.

Part objects are more complex than mesh objects created with the Mesh Workbench, as they permit more advanced operations like coherent boolean operations, modifications history, and parametric behaviour.

The Part Workbench is the basic layer that exposes the OCCT drawing functions to all workbenches in FreeCAD.

ツール

パートモジュールツールは全てパートモジュールを読み込んだ時点で表示されるPartメニューにあります。

Primitives

These are tools for creating primitive objects.

  • Box: Draws a box by specifying its dimensions
  • Cylinder: Draws a cylinder by specifying its dimensions
  • Sphere: Draws a sphere by specifying its dimensions
  • Cone: Draws a cone by specifying its dimensions
  • Torus: Draws a torus (ring) by specifying its dimensions
  • Tube: draws a tube by specifying its internal radius and external radius. introduced in version 0.19
  • Primitives: A tool to add any of the defined geometric primitives.
  • Builder: A tool to create more complex shapes from various parametric geometric primitives

Modifying objects

These are tools for modifying existing objects. They will allow you to choose which object to modify.

  • Extrude: Extrudes planar faces of an object
  • Revolve: Creates a solid by revolving another object (not solid) around an axis
  • Mirror: Mirrors the selected object on a given mirror plane
  • Fillet: Fillets (rounds) edges of an object
  • Chamfer: Chamfers edges of an object
  • Ruled Surface:
  • Loft: Lofts from one profile to another
  • Sweep: Sweeps one or more profiles along a path
  • Offset tools:
    • 3D Offset: Constructs a parallel shape at a certain distance from original.
    • 2D Offset: Constructs a parallel wire at certain distance from original, or enlarges/shrinks a planar face.
  • Thickness: Hollows out a solid, leaving openings next to select faces.
  • Boolean: Performs boolean operations on objects
  • Cut: Cuts (subtracts) one object from another
  • Fuse: Fuses (unions) two objects
  • Common: Extracts the common (intersection) part of two objects
  • Join features: smart booleans for walled objects (e.g., pipes).
    • Connect: Connects interiors of objects.
    • Embed: Embeds a walled object into another walled object.
    • Cutout: Creates a cutout in a wall of an object for another walled object.
  • Splitting tools:.
    • Boolean fragments: makes all the pieces that can be obtained by Boolean operations between objects.
    • Slice a part: tool to split shapes by intersection with other shapes
    • Slice: Splits an object into pieces by intersections with another object.
    • XOR: removes space shared by even number of objects (symmetric version of Cut).
  • Defeaturing:
  • Section: Creates a section by intersecting an object with a section plane
  • Cross sections...: Creates one or more cross-sections through a selected shape
  • Attachment: attachment is a utility to attach an object to another one.

Measure

File:Part Measure Menu.png Measure: Allows linear and angular measurement between points, edges, and faces.

Other tools

Context menu items

  • Appearance: determines appearance of the whole part (color transparency etc.).
  • Set colors: assigns colors to part faces.

Preferences

  • Preferences: preferences available for Part Tools (the Part workbench also uses the PartDesign Preferences).
  • Import Export Preferences: preferences available for importing from and exporting to different file formats.
  • Fine-tuning: some extra parameters to fine-tune Part behavior.

スクリプト処理
