I have some parts with a pitch >= 1.27mm with a pin 1 dot.
For these parts I can easily change the exported 3D step model before I integrate it into the layout library.
Thanks for Your quick answer.

SOIC's with a 0.05" (1.27 mm) pin pitch do not have a Pin 1 dot on the physical package.

Only metric pin pitch parts have a Pin 1 Dot.

You can color the Pin 1 3D Model Lead to a different color, but you cannot change 3D Model images in Library Expert.

How can I configure a Pin 1 dot instead of a Pin 1 chamfer for the 3D Step export?
Sample pictures and sample library attached.
