Is it possible to design chamfered optical elements, like in the left lens in the attached picture? If so, how should I define the mechanical semi-diameters to achieve this?

Hi
In the properties of the left-most surface, navigate to the Draw tab, and choose Draw Edges As: Tapered To Next Surface.
Note that you shouldn’t use the mechanical semi-diameter, but either simply the clear semi-diameter, or use a Chip Zone. Otherwise the tapering might not appear as you want to. See my examples below:
In both cases, the clear semi-diameter is 8, but in the first case, the fixed Mech Semi-Diameter adds a flat shoulder to the lens, whereas in the second case, the Chip Zone conserves the radius of curvature. Let me know if this is clear.
Take care,
David
Thank you for the reply! I was not aware of these features.
