Compute the silhouette region of a surface consisting of unordered 3dface entities on a reference plane.
8 Menu: ComputationalCAD Compute silhouette
7 Command entry: CC:FACES:SILHOUETTE
Select the 3dfaces defining the surface.
Specify reference plane
Specify the reference plane of the silhouette. Default is <Wcs>.
Minimum projected edge
Specify the minimum length of the projection of the faces onto the reference plane. Default is <0.01>.
The silhouette of a surface is the visible outer bound of all faces. In order to do this, the projection of the input faces onto the reference plane must not be degenerate. In order to achieve this, the projected faces will be healed so that no projected edge will be shorter than specified.
