Q - question

How to project geometry to any 3D surface.

A - answer One of the new powerful 3D functions in AutoCAD 2011 (and higher) is the PROJECTGEOMETRY command, which can project - drape - any curve, polyline, line or point to any 3D surface.

You can specify the project direction by the current view, by the direction vector, or by UCS. The projected geometry is displayed (as splines) on the selected 3D solid or surface body (incl. NURBS surfaces).

You can use this command e.g. to project texts (TXTEXP exploded) to free surface meshes.

Text projected to NURBS surface

For projecting to a sphere use the SphereProj utility.
