开源CAD——从源代码安装到依赖关系分析 __02

开源CAD——从源代码安装到依赖关系分析__02

首分成4大类,

1,FreeCAD+openCASCADE

2,LibreCADorQcad,

3,OpenSCAD

4,gCAD3D

othersPythonCAD,salome,varkon,CADvas,etc...(资料相对不太完善)

关于文件格式的介绍：

二维软件主要以dxf,xxx.py为主，autodeskCADformat.
三维的格式主要以stl为主。3Dsystemformat.

且都可以输出图片格式。

本节主要介绍第一类FreeCAD+OpenCASCADE，
