简介
FreeCAD的实体建模能力都是基于 Open Cascade Technology (OCCT)内核——一种具有创建与处理3D几何体等高级特性的专业级CAD系统. 零件工作台（Part Workbench）是一种建立于OCCT库之上的层级，为用户提供了访问OCCT几何图元与函数的功能. Essentially all 2D and 3D drawing functions in every workbench (Draft, Sketcher, PartDesign, etc.), are based on these functions exposed by the Part Workbench. Therefore, the Part Workbench is considered the core component of the modelling capabilities of FreeCAD.
