The Facet Modeling Workflow
A typical facet modeling session would progress in this fashion:
• Point handling
◦ Import the point set using > > , select a .pts, .acs, .vtx, or .ibl file, and select Facet as the import type.
◦ Eliminate erroneous data such as points lying outside the required geometry
◦ Add additional point sets into the same feature
◦ Delete points if required
◦ Minimize noise
◦ Sample points to clean data and also reduce the computation time
◦ Create a wrap from the point set
• Wrap handling
◦ Remove triangles by propagating through the surface in a selected area or until the point density changes
◦ Remove webs that are generated in open spaces in the model while creating a wrap from a point set
◦ Remove triangles in a straight line throughout the model, similar to drilling a hole
◦ Add a single layer of triangles to a selected area of geometry
◦ Fill any concave parts of the geometry that you select
◦ Fill areas that require additional volume in order to define edges that may have been blurred during scanning
• Facet handling
◦ Delete facets that are not required
◦ Reduce the number of triangles without compromising surface continuity or detail
◦ Fill gaps that may have been introduced during the scanning process
◦ Improve the faceted geometry by reducing facet size
◦ Smooth the polygonal surface by changing the coordinates of the vertices in an iterative manner
◦ Reverse the orientation of two facets that share an edge
◦ Add facets by splitting an existing facet or by selecting three open vertices and creating a new facet
