Hi,
V5
opening a solid which used the stock default red for my layer with cutting surfaces (objects colour by layer) into CAD prog ‘spaceclaim’ sees it become a different colour, so my ‘cutters’ are no longer the red I give them. They look like part of the object, not as their intended use. Other colours also changed. I know my structure and options in use by the colours.
in Spaceclaim go to File> Spaceclaim Options>File options and look for the toggles to preserve colors. I don’t recall if it looks at part color per layer or actual object color.
So if your objects are not re don import you can run a script to turn layer color to object color in Rhino before export, but I don’t think it’s needed.
