I have two surfaces, one of which (green) is created by mirroring the other (purple). Using the
Dir command in Rhino shows that the UV directions on the surfaces are also mirrored.Here’s a screenshot:
When I export these surfaces as IGES and then re-open the model, the U and V directions are swapped on the mirrored surface, shown here:
Is there a way to stop this from happening, or is it a limitation from iges? Is it some artifact from mirroring?
I need to be able to determine what the UV directions will be when exported. Is there a reliable way to do this from within Rhino without going through the export/import cycle?
