Introduction

FreeCAD 的電腦輔助設計功能建構於 OpenCasCade 核心。物件坊讓 FreeCAD 取用 OpenCasCade 物件與功能。OpenCasCade 是一專業級電腦輔助設計核心，善於空間幾何控制與物件。不同於 網狀模組 物件，物體物件更加複雜，因此容許更多進階操作，例如一致布林操作、修改歷史和參數行為。

A more detailed discussion of Part workbench versus Part Design workbench can be found here: Part and Part Design.

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.

工具

所有零件坊工具皆置於物件選單，載入物件坊時顯示。

Primitives

These are tools for creating primitive objects.

  • Box: Creates a box.
  • Cone: Creates a cone.
  • Create primitives...: A tool to create one of the following primitives:
    • Plane: Creates a plane.
    • Box: Creates a box. This object can also be created with the Box tool.
    • Cylinder: Creates a cylinder. This object can also be created with the Cylinder tool.
    • Cone: Creates a cone. This object can also be created with the Cone tool.
    • Sphere: Creates a sphere. This object can also be created with the Sphere tool.
    • Ellipsoid: Creates a ellipsoid.
    • Torus: Creates a torus. This object can also be created with the Torus tool.
    • Prism: Creates a prism.
    • Wedge: Creates a wedge.
    • Helix: Creates a helix.
    • Spiral: Creates a spiral.
    • Circle: Creates a circular arc.
    • Ellipse: Creates an elliptical arc.
    • Point: Creates a point.
    • Line: Creates a line.
    • Regular polygon: Creates a regular polygon.

Creation and modification

These are tools for creating new and modifying existing objects.

  • Revolve: Creates a solid by revolving an object (not a solid) around an axis.
  • Mirror: Mirrors the selected object across a mirror plane.
  • Fillet: Fillets (rounds) edges of an object.
  • Chamfer: Chamfers edges of an object.
  • Loft: Lofts from one profile to another.
  • Sweep: Sweeps one or more profiles along a path.
  • Section: Creates a section by intersecting an object with a section plane.
  • Offset tools:
    • 3D Offset: Constructs a parallel shape at a certain distance from an original.
    • 2D Offset: Constructs a parallel wire at certain distance from an original, or enlarges/shrinks a planar face.
  • Attachment: Attaches an object to another object.

Boolean

These tools perform boolean operations.

  • 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:
    • Connect: Connects interiors of walled 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: Creates all pieces obtained from Boolean operations.
    • Slice apart: Slices and splits an object by intersecting it with other objects.
    • Slice: Slices an object by intersecting it with other objects.
    • XOR: Removes space shared by an even number of objects.

Measure

File:Part Measure Menu.png Measure: Tools for linear and angular measurements.

Other tools

  • Import: Imports from *.IGES, *.STEP, or *.BREP files.
  • Export: Exports to *.IGES, *.STEP, or *.BREP files.

Context menu items

  • Appearance: Determines the appearance of a whole object (color, transparency etc.).
  • Set colors: Assigns colors to individual faces of objects.

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.

Scripting

See Part scripting.
