Compute All breaks Cut Combine

[thomasa88]

I'm trying to subtract a body (Measure) from another (Mold). At first it works, but as soon as I do "Compute All", the resulting body breaks.

I have attached the document and an example video.

Is the image below what you are trying to achieve ??

If yes then try the modified file below and check the timeline for the operations used.

If not then Ooops, Doh, aplogies 🙂 🙂 🙂

Stay Safe

It should not be a factor but the suppressed sketch and extrusion, in the timeline (marked), is causing the issue you are seeing when you select Compute All.  I cannot explain why maybe @jeff_strater can give you a idea but that is the cause.  Model attached.

@engineguyThanks for giving it a go, but it was not the end result I was after.

@jhackney1972  Thank you! That is so strange. It also works when I suppress those deleted features, so it's not their geometry that is messing with the combine.

On a general note, if someone is troubleshooting Fusion 360: I had missed some things in my early steps when doing my design, so the file is a result of recreating several features and reordering the timeline.

that is a very strange one.  Been over it a dozen time, and I still don't get it.  Not sure how that "33" on the bottom could possibly affect the Combine.  I did notice that editing the Combine feature after the Compute All produces the correct behavior.  Will continue to investigate, but this is clearly a bug...
