I’m in the middle of creating a polysurface for export to Revit via .sat. However, The corner surfaces are creating a bit of an issue. As you can see in the attached images, these surfaces display normally when viewed perpendicularly, but reveal a sort of saddle shape when viewed from the edge. However, The surface contours as would be expected (all arcs) and a medium density mesh created from the surface also appears as expected. This happens regardless of if the corner surfaces are joined to the others or not. Changing the render mesh settings doesn’t change anything.
These surfaces are created from a loft in Grasshopper, but the corners always have to be rebuilt by sweeping arcs along the tangent surfaces. The polysrf won’t close with the geometry that is baked from the script.
Any help would be appreciated.
