Dear Community,

I have a problem when I want to export my lens data to a STEP file. It is somehow distorted when I open it with Solid Edge. I tried also Autodesk Inventor, but it looks the same. Please find attached my mirror design (Elliptical Mirror CAD) as well as how it looks like with Solid Edge. I already checked that ACIS Libraries are not set.

What confuses me is when I reduce the aperture (which is elliptical) in x-direction from 120 to 80 it works. Please also find those files attached (Elliptical Mirror CAD 2 and Elliptical Mirror Solid Edge 2).

Do you have an idea how I could fix this problem?

Thank you very much in advance.

Best regards,

Andy
