Two figures in Sketch -> Pad/Pocket does not work

[DL8RI]

Hi,

maybe it's a Bug, maybe I just have to adapt to the new Part-Design workflow...
I want to create a body with two holes in it. With the 0.16, I created the volume, added a sketch with two circles and did the pocket-operation.
With the latest 0.17, it does not work anymore. I get the messages "Tip shape is empty (but must be executed)" and "TopoDS::Face".

If I remove one circle it works without problems. Same problem with other shapes.

Now the question is: Bug or feature?


Edit: Changed Title... Of course ist Pad & Pocket and not Loft & Pocket, silly me.

can you post a detailed step-by-step guide, or a file, or both...?

Hi,

thanks for the fast reply

If you try a pocket with the attached File (problem.FCStd) it should not work.

What I did:
Create a sketch with two intercepting rectangles and Pad this one to a Bar as shown.
Create a second sketch on one surface and draw two Independent shapes (two cicles or a rectangle and a circle), and then try to pocket.

I made more or less the same with the 0.15 Stable, and it works... (probem2_0-15), just for a comparison (File and Picture attached).

Thanks, now I can reproduce. So the key seems to be that two circles should not be one inside other. Like making two independent pockets with one sketch.

Exactly. Typical application would be several screw-holes in a metal plate (wich is what I wanted to do).
After some additional tests, I can't find an error on my side, so probably it's a bug?!

Should I put it in the tracker, or, since AFAIK you are a devoloper of PartDesign, this not needed anymore?

[DeepSOIC]

Please put it into tracker. I'm not currently involved in development, that was almost a year ago. I may come in again, eventually...

I confirm the bug as well. There should be no problem with creating a pocket from a sketch containing multiple non-intersecting profiles.

Create a sketch with two intercepting rectangles and Pad this one to a Bar as shown.

For the bug report I suggest supplying a simpler test case. The Pad's sketch only needs a single rectangle to reproduce the bug.

The bug affects Pad as well, and I assume the other additive/subtractive tools.

Bug reported by DL8RI as issue #2512.

I got this yesterday, is there any workaround? its a bit of a pain to add one hole/sketch ^_^

Hi,
could anyone confirm that the latest git has a fix for this problem?

For me it pads only one circle. No error messages in the console.

Thanks.

Cheers,
