Description: draw contour levels on a 3D model

TopoLT toolbar:

Menu: TopoLT » 3D Model » Contour levels

Using this command you can draw contour levels for one or more 3D models. Field 3D model can be created using command M3D.

Field 3D model for which you draw contour levels can be formed from triangles or quadrilaterals. Entities from 3D model can be: 3DFace, PolygonMesh or PolyFaceMesh.

In case of triangles drawn with 3DFace point number 4 must be identical with point number 3, triangle will be formed through points 1-2-3.

In case of quadrilaterals interpretation is made for two triangles that will be build through 1-2-4 and points 2-3-4 (in the same way of work as CAD programs).

When contour levels are very dense program runs slower. To stop this function during running press <Esc> and then command Undo. To increase processing speed of this command increase contour levels equidistance.

Configuration for contour levels drawing mode can be realized using command Om3d and parameters description for contour levels drawing you can find at section 3D model.
