Abstract: Taking
AutoCAD2000 as platform, an algorithm for the reconstruction of
surface from scattered data points based on VBA is presented.
With this core technology customers can be free from traditional
AutoCAD as an electronic board and begin to create actual
presentation of real-world objects. VBA is not only a very
powerful tool of development, but with very simple syntax.
Associating with those solids, objects and commands of AutoCAD
2000, VBA notably simplifies previous complex algorithms,
graphical presentations and processing, etc. Meanwhile, it can
avoid appearance of complex data structure and data format in
reverse design with other modeling software. Applying VBA to
reverse engineering can greatly improve modeling efficiency and
facilitate surface
reconstruction.
