Hello 

I have some trouble in defining the ISO file of an off axis conic mirror. 

The design looks like that 

and the I can manage to do better for the ISO file. 

 

 How do you proceed in such a case ? 

Thank you very much in advance for your help and have a nice day 

Pascale

Hi Pascale, ISO Drawing doesn't support not rotationally symmetrical surfaces. Currently source code of ISO drawing unable to calculate the real position because of off axis and there fore the radius mismatch happens.
