Creates a cross profile through the 3D model.

If the 3D model wasn't selected with the command SelM3D then it is asked to select the 3D model.

The obtained 3D polyline will always be projected on the section line of the cross profile, because of this we recommend that the selected polylines to be along a line in the 2D plan.

The description data of the cross profile are similar and you can find them at the description of the command MakePT.
