FRAME CAD SYSTEM

This system is developed（based on PANDA-3D） for efficient frame design．Frame is constituted by welding the bar section parts．User can sketch the spatial frame just using the axes of parts，then choose the type of bar section for parts．After that，the system can establish the assembly relationship between bar section parts，generate the assembled solid model of the whole 3D frame automatically．This system is successfully applied in fixture frame design for new aeroplane．
