Pull of Nurbcurves

#### Description:

When pulling surfaces that have lines which are defined by nurb surfaces the system fails. This should be handled in some way.
A potential fix could be to apporximate the numbs curve by a polyline.

No files, tests, or entry points are identified in the issue. Locate the code that pulls surfaces and determine how lines defined by NURBS surfaces are handled; done means those surfaces are pulled without failure, with an agreed handling such as approximation by a polyline.
