Introduction
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.

Offset:
- 3D Offset: 根据原始几何形状在特定的距离处构建一个平行的副本。
2D Offset: 根据原始连线在特定的距离处创建一个平行的副本，或者缩放一个平面端面。
Thickness: 镂空一个实体，在选中的面上留下开口。
Projection on surface: 向表面上投影logo、文本或任意表面、连线、边。可以为投影部分创建一个示例或连线。
Color per face: Assigns colors to individual faces of objects.
Boolean toolbar
Compound:
- Make compound: Creates a compound from the selected objects.
Explode compound: Splits up compounds.
Compound Filter: Extracts the individual pieces from compounds.
Boolean: 在对象上执行布尔运算
Cut: Cuts one object from another.
Union: Fuses two or more objects.
Intersection: Extracts the common part of two objects.
Join:
- Connect objects: Connects interiors of walled objects.
Embed object: Embeds a walled object into another walled object.
Cutout for object: Creates a cutout in a wall of an object for another walled object.
Split:
- Boolean fragments: Creates all pieces obtained from Boolean operations.
Slice apart: Slices and splits an object by intersecting it with other objects.
Slice to compound: Slices an object by intersecting it with other objects.
Boolean XOR: Removes space shared by an even number of objects.
Check geometry: Checks the geometry of selected objects for errors.

- Create a copy:
Create simple copy: Creates non-parametric copies of objects.
Create transformed copy: Creates non-parametric copies of objects. It is intended for objects nested in containers.
Create shape element copy: Creates non-parametric copies of subelements: vertices, edges and faces.
Refine shape: Creates parametric copies with a refined shape from selected objects. It removes unnecessary edges from planar and cylindrical faces.
Attachment...: Attaches an object to one or more other objects.
