Cannot pad from datum plane attached tangent to curved pad

Post by exsolvespacer »

In this file, Pad003 only appears when the pad is greater than 5mm. I would like it to be 1.75mm. What am I doing wrong? Thanks.

Origin of the Part seems to be broken, perhaps because I don't use Link branch; I have deleted the whole container - without its conents, of course.

The pad works with 1.75mm in master:

Okay, I'll see what RT says about this as it looks like a bug. Thanks for checking it in master.

RT says it is a "common OCC tolerance problem" and suggested doing a pad followed by a pocket. This solved the problem.
