boundary fill gives no warning when it fails (no yellow icon in timeline)

[derProtoTyp]

I´m twaking a somewhat complex shape that is generated via several surfaces and a boundary fill command. unfortunately when I tweak the sketches that generate the curves and move a point too far, the boundary fill stops to update. that is expected. but it does not give a warning (yellow icon in the timeline). several times this made me move arround points, wondering why nothing is updating.

Hi @derProtoTyp,

Taking a bit of a stab here - if you do a Compute All from the Modify menu (which recomputes the timeline) after a boundary fill failure do you see it generate warnings/failures? I'm not sure if dragging sketch elements forces a full compute of the timeline which would probably generate the error. If not, then certainly something strange is going on as it should populate some warning.

Thanks,

hi @James.Youmatz 
thank you for looking into this issue - maybe that was not very obvious in the screencast but I triggered the compute all command twice without any warnings. ...did it via the s key search menu... (s com... arrow down enter) but just in caste that would make any difference I just tried via the modify menu as you suggested. same behaviour. can you reproduce this behavior on your computer? I could only test on two windows machines (both win10).
all the best

I can reproduce the behavior with dragging sketch curves so that the surfaces no longer overlap, and the Boundary Fill fails silently, and can acknowledge that it is a bug. 

One thing I would like to point out, however, is that this situation:

when you have deleted all the sketch curves, causing the extrudes to fail, but the Boundary Fill does not fail, is not a bug.  The Extrudes have all failed in a warning state, but Fusion still has the cached outcome of those Extrudes, which is why the Boundary Fill succeeds.

[edit] bug is FUS-54232

Hi @jeff_strater,
thank you for your reply!
Absolutely! My deleting of the curves in the screencast was confusing. Its the expected and correct bahavior that these subsequent features still exist because of the cashed geometry.

If anyone has the same issue/workflow:

One workaround for me right now is to add a small surface (tube for instance) that allows for a second cell to be generated in the Boundary Fill but not select that small cell. So instead of my main cell failing silently the Boundary Fill "jumps" to this second possible cell, at the moment I move the curves too far - which makes it very obvious.

and one final side note to my workaround: when my small "helper" cell is inside the main cell and I have to select it also to get my desired shape, Boundary Fill fails as expected (with warning and yellow icon in the timeline) when curves get moved too far. So aparrently the bug only occures when there is only one cell? Maybe that helps...
Kind regards

thanks for the info, @derProtoTyp - you may be correct, that this is a problem only when there is one cell.  Nice debugging!
