Hi Dries Glad to see you here Remember that ICAD supports direct Rhino integration : you can import advanced surfaces modeled in Rhino and add mechanical features in IronCad. Then, from IronCAD Structure Panel you can right click on the Rhino object to edit it with Rhino. Arnaud

KS 5 supports now direct NURBS rendering, without triangles. This is very nice to avoid smoothing issues. Hope that the plugin will support this feature (still available for Rhino)

Hi Another way 1 - Sketch > Draw a polygon (8 sides or more but an even number) 2 - 3D curve > Spline passing through vertices 3 - Use Triball to move 4 (or total number / 2) points up 4 - Sketch > rectangle 5 - Sweep wave_washer_AC.ics
