    Are there any coding examples of the new NURBS commands (e.g. NURBSCURVE3D, NURBSSURFACE etc)? I’ve looked at the command descriptions in the GDL Reference Guide, but they’re quite difficult to understand. Coding examples, as per the other commands, would be very useful.

    I think it’s safe to conclude, from the lack of response, that no such GDL examples exist yet (at least from Graphisoft – I know ArchiRadar have a nice object).

    However, to get the ball rolling, can someone tell me what the NURBSCURVE2D and NURBSCURVE3D commands do? I thought they would create a visible 2D or 3D line…but that doesn’t appear to be the case. They aren’t primitives, as these NURBS commands exist elsewhere…so I can’t figure it out.

    Thanks.

    Please read the documentation, it is written there: “The NURBSCURVE2D, NURBSCURVE3D and NURBSSURFACE statements create only geometrical elements in the NURBS body which will not be visible themselves
