Our testing has shown that Orca3D works smoothly in Rhino 7, and SubD surfaces are compatible with calculations such as Sections, Hydrostatics & Stability, Speed & Power, and Weight & Cost. Real-time sections currently do not work with SubD models; that is, the sections don’t update as a control point is moved, but they do update when the control point is put down.
Orca3D Version 2 is compatible with both Rhino 6 and Rhino 7. No update to Orca3D will be required for Rhino 7.
