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。

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: 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.
  • Shapebuilder: 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
  • Thickness: Hollows out a solid, leaving openings next to select faces.
  • Boolean: Performs boolean operations on objects
  • Union: Fuses (unions) two objects
  • Common: Extracts the common (intersection) part of two objects
  • Cut: Cuts (subtracts) one object from another

Measure

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.

Scripting

See Part scripting.
