Reply To: Incomplete indicator shape
As you implemented a custom indicator for your fin shape (which is the correct way to go for non-primitive shapes that are not easily reproduced using indicator arithmetic) there is likely something wrong in the custom operator(). Can you tell us more about the specific “fin” geometry you want to model?
The reason why this is not an issue for CAD-imported geometries is that the STL reader indicator is designed to correctly import arbitrary STLs.
