基于PARASOLID的CAD系统开发

PARASOLID:based CAD System Architecture

以SketchUp等CAD系统为原型,研究了基于PARASOLID的CAD系统开发的三个关键步骤,即系统框架的构建、三维建模功能的完善以及约束规则的建立。整个架构对于其他平台上的CAD系统开发具有指导意义,也可以为进一步研制手绘CAD系统以及概念设计CAD系统提供基础。

SketchUp being prototype, studied the three key steps in CAD system development based on PARASOLID building the system framework, completing 3D modeling and establishing the constraint rules. This architecture can act as guidance to CAD system development on other platforms including ACIS, CAS. CADE, etc. This architecture underscores segregation of responsibility, thus easy to extend to a more sophisticated system such as Computer Aided Conceptual Design （CACD） system.
