FreeCAD's CAD kapabilitet är baserad på OpenCasCade kärnan. Del modulen tillåter FreeCAD att komma åt och använda OpenCasCade objekt och funktioner. OpenCascade är en professionell CAD kärna, som erbjuder avancerad 3D geometrimanipulation och objekt. Del objekten, till skillnad från Nätmodul objekten, är mycket komplexare, och tillåter därför mycket mer avancerade operationer, som koherenta booleska operationer, ändringshistorik och parametriskt beteende.

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.

Förändra objekt

Detta är verktyg för att förändra existerande objekt. De kommer att låta dig välja vilka objekt som du vill förändra.

  • Extrudera: Extruderar plana ytor på ett objekt
  • Rotera: Skapar ett objekt genom att rotera ett annat objekt runt en axel
  • Spegling: Speglar de valda objekten runt en given axel
  • Fasning: Fasar (rundar) kanterna på ett objekt
  • Fasning: Fasar (klipper) kanter på ett objekt
  • Ruled Surface:
  • Loft: Lofts från en profil till en annan
  • Sweep: Sopa en eller flera profiler längs en bana
  • 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.


These tools perform boolean operations.

  • Boolean: Utför booleska operationer på objekt.
  • Cut: Cuts (subtracts) one object from another.
  • Fuse: Fuses (unions) two or more 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.


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 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.
