| Abstract: | In AutoCAD 2000 development platform, building a VC++6.0 executable application for Windows that is based on the Microsoft foundation class (MFC) library, integrating ActiveX automation technique derived from COM and ARX technique in ObjectARX environment, the project frame is established. This paper provides detailed methods to operate database of AutoCAD and outer database. Presenting a global fairing method, the curve fairness criterion of the algorithm, i.e., strain energy minimization and uniform change of curvatures, is defined. Establishing cubic B-spline objective function equation, the fairing curves are achieved successfully. |
