Pocket outside pad boundaries

Postby pmarches » Sat Jul 13, 2019 4:48 pm

Hello,

I am trying to make a pocket on a pad with a curved face. When the pocket is fully within the pad, the pocket works just fine

.

However, if any part of the pocket falls outside the pad (by making the pocket wider), the pocket no longer is applied properly. In the big pocket screenshot you see only a thin line on the pad where some of the pocket should have been extruded.

How can I extrude a slope from a pad, if I cannot make the pocket exactly the same shape as the pad?

Thank you!

Hi pmarches, welcome.
Your Sketch009 has a missing coincidence. You can find & fix it with Sketcher ValidateSketch.
Even with that corrected, running a geometry check with extra BOP tells that your Pad011 isn't a valid solid :

I didn't investigate deeper, but it's probably the reason why the subsequent pocket fails. ;)

There's a seam in the yellow face I've pre-selected in the image below.

I don't think a seam should be there, and also suspect that it is where the problem is located. If you create a Periodic B-Spline in Sketcher and Close it with a right-mouse button click, you won't get a seam.

Maybe a bug? :roll:
But by making a half hull, it's could be help you.
