Re:认为PRO/E的两个船体模块有搞头的弟兄举手!:)
any programs and algorithms exist for "skinning" a surface through a series of offsets, including most major CAD systems, such as ProEngineer™, Autodesk’s AutoSurf®, Intergraph EMS™, as well as some hull design programs. Why not just push the button in one of these programs and call it a day? After all, they claim to create a surface that passes through the given offset points, and NURBS mathematics tells us that a surface can be found that will pass through each of the offset points. This is a classic case of "when things seem too good to be true, they usually are". |
