This command creates contours directly from displayed
Triangulated Irregular Network (TIN) surface features (triangles),
optionally creating an external Triangulation File (.TIN) in the
process. The user is prompted to pick a sample of the TIN to
process. This will automatically filter out all other entities that
don't reside on the layer of the displayed TIN faces. The triangles
must be drawn on the screen as 3D Lines or 3D Faces. All of the
settings for Triangulation, Contouring and Labeling, found in
Triangulate and Contour
are available. See the Triangulate and Contour section in the
manual for a detailed description of each of these
settings.
It is not recommended to use the "Subdivisional Surfaces" option in the Contour tab when using this routine. Use of this option with this routine may allow the internal reconfiguration of triangles that have been formed along breaklines.
