This command creates a profile from surface entities with one of the specified layers. The surface entities can be contours, triangular mesh, and other 3D drawing entities. This command is the same as Profile from Surface Entities with the addition of the layer filtering. The method is to draw a polyline as the profile centerline. Then run Profile by Layers and specify the layer names of the surface entities to include in the profile. For example, the layer names CTR and TMESH could be entered to use only the contour polylines and triangulation mesh on these layers. Entities on all other layers would be ignored. The profile is derived from the intersections of this polyline with the 3D entities on the specified layers.
