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高级3D几何体等特性的专业级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。每种工作台(如底图工作台, 草图工作台, 零件设计工作台等等)的一切2D与3D绘制功能其实都是基于零件工作台暴露出的函数实现的。因此,可以认为零件工作台是FreeCAD建模功能的核心组件。
The Part Workbench can also create objects that are not solids, such as faces, shells, and objects with only edges or vertices. It also provides a variety of general purpose tools for geometry manipulation, geometry validation, and making copies.
The PartDesign Workbench uses an alternative workflow for creating solids. For a detailed discussion of the Part Workbench versus the Part Design Workbench see Part and Part Design.
The Std Measure tool replaces the tools listed below. introduced in version 1.0
