CAD možnosti FreeCADu jsou založeny na jádře OpenCasCade. Modul Díl umožňuje FreeCADu přístup a používání objektů a funkcí OpenCasCade. OpenCascade je profesionální CAD jádro, jehož vlastnosti umožňují pokročilou manipulaci s 3D konstrukcemi a objekty. Objekty Díl, narozdíl od objektů Modulu Síť, jsou mnohem komplexnější a proto umožňují mnohem dokonalejší operace, jako jsou logické boolean operace, modifikace historie a parametrické chování.

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.

  • Part Torus.svg Torus: Draws a torus (ring) by specifying its dimensions
  • Part Tube.svg Tube: draws a tube by specifying its internal radius and external radius. introduced in version 0.19
  • Part Primitives.svg Primitives: A tool to add any of the defined geometric primitives.
  • Part Shapebuilder.svg 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.

  • Part Extrude.svg Extrude: Extrudes planar faces of an object
  • Part Revolve.svg Revolve: Creates a solid by revolving another object (not solid) around an axis
  • Part Mirror.svg Mirror: Mirrors the selected object on a given mirror plane
  • Part Fillet.svg Fillet: Fillets (rounds) edges of an object
  • Part Chamfer.svg Chamfer: Chamfers edges of an object
  • Part RuledSurface.svg Ruled Surface:
  • Part Loft.svg Loft: Lofts from one profile to another
  • Part Sweep.svg Sweep: Sweeps one or more profiles along a path
  • Part Thickness.svg Thickness: Hollows out a solid, leaving openings next to select faces.
  • Part Booleans.svg Boolean: Performs boolean operations on objects
  • Part Fuse.svg Union: Fuses (unions) two objects
  • Part Common.svg Common: Extracts the common (intersection) part of two objects
  • Part Cut.svg Cut: Cuts (subtracts) one object from another

Measure

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.).
  • Part ColorFace.svg Set colors: assigns colors to part faces.

Preferences

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

Skriptování
