Introduction
FreeCADのCAD機能はOpenCasCadeカーネルをその基礎としています。FreeCADはパートモジュールによってOpenCasCadeオブジェクトとその機能へのアクセス・利用を行なっています。OpenCascadeはプロフェッショナル用のCADカーネルでその機能は3D形状操作、3D形状オブジェクトに特化しています。メッシュモジュール のオブジェクトと異なりパートオブジェクトはより複雑で、明確なブーリアン演算、変更履歴、パラメトリックな動作などのより高度な処理が可能です。
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.
