Part Module/sv



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.

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.
