CAD model creation and
error analysis

• Based on the contours representing the arm geometry, surface and solid models of an arm were constructed using CAD packages  UniGraphics and ProEngineer.
• Error analysis was accomplished between the CAD model and the “approximate point cloud” extracted from the “raw scanning data” (see Fig. 3).
• Error analysis was also accomplished between the CAD model of an arm and the “original raw scanning data”.
