ABSTRACT:
A mechanism for enabling a user to treat 3D scan data model regions as surface bodies so as to eliminate the need to convert model regions to parametric surfaces as a prerequisite to performing part body modeling operations is discussed. During CAD re-modeling raw 3D scan data is imported. The present invention allows a user to use a region directly as an input argument for a part body modeling operation as long as a sheet body (surface body) is applicable as a modeling input argument. Additionally, if any regions used in the body modeling are modified by the user, surfaces which have been generated from fitting regions are also recalculated and the body model is updated automatically. The region modification can happen when the user includes more scan data in the region, excludes scan data from the region, smoothes geometry, or uses other editing functions.
