I'm new to OCC technology and I'm looking for some guidance on a particular task. I'm working predominantly with NURBS surfaces that are exported as a STEP file from CAD software. What I want to do is read the STEP file and extract the NURBS data structures (i.e. knot vectors, degrees, control point connectivity, control point coordinates).
I've compiled the STEP reader example but I'm unsure what classes I will need to extend this code to extract the NURBS data. Can anyone point me in the right direction?
