Ticket #3436 - Fillet crash FC daily

[chrisb]

I remodeled your design so it gets more robust and uses far less operations. The clue was to model only a quarter of the top sliders and then use only one multipattern.
For external references it is sensible to use sketches instead of edges, to be seen e.g. in Sketch008. It makes the model more robust. For that it might have been better to place the XZ-plane on the top and not in the middle of the object, although I am not absolutely sure about the consequences.
Another possibility to increase robustness is the use of Expressions as seen in Sketch011. I left that with the BSpline, although I would myself have modeled this with two tangent circles of different diameters.

I replaced the other BSplines with the last two fillets. If you want something more fancy you can modify Sketch007.

One further remark: In Sketch007 you have a redundant constraint, the symmetry implies the vertical constraint. This breaks a model in later steps.

Can anyone reproduce this crash on 0.18 as well ?

It doesn't for me, it throws an error. And a Refine on the last feature fixes that.

I cannot reproduce this crash:

Can anybody still reproduce?

Yes.
I first tried with the file from the OP as it is. Opened it, selected that edge, PartDesigh fillet - object disappears, no error is shown. So I tried with a smaller fillet - selected radius field, typed "0", ",", "1". After some thinking without nothing shown FreeCAD crashed. So I opened the file again and this time first made full recompute in case some old wrongly generated geometry was the culprit. Because of tooponaming Datumplane moved and now the model was wrong. I fixed the mapping and again tried to fillet that edge - same result at setting it to 0,1mm. Attached is my modified file before the fillet.

Oops! I had just retested with success and have closed the ticket. Can you reopen it?

Attached is my modified file before the fillet.

Cannot reproduce here. I get an error in report view on each keypress.

I was looking at python console instead of report view In report view I get this trying to fillet my file:

Finally this is perhaps a different error which was fixed quite some time ago. Can you try to enter just zero and wait if FreeCAD crashes?
