基于OpenCASCADE的CAD软件

OpenCASCADE是一套开源的CAD/CAM/CAE几何模型核心，来自法国Matra Datavision公司，是著名的CAD软件EUCLID的开发平台。

Euclid is a CAD software which was developed since 1980 by the French company Matra Datavision. Matra then developed EUCLID QUANTUM, a new generation in 1996, on the platform CAS.CADE (Computer Aided Software for Computer Aided Design and Engineering). As in 1998 Matra Datavision specialized in software service provider, Dassault Systèmes acquired QUANTUM products : Euclid Styler and Euclid Machinist.

In 1999 Matra Datavision published CASCADE in open source on the Internet as Open CASCADE .

FreeCAD是一个基于OpenCASCADE的开源CAD/CAE工具。
