instant crash when trying to chamfer or fillet

Post by miniellipse »

I get an instant crash when I try to chamfer or fillet in my part. See highlighted edge for the problem location:

I may be asking FCAD to fillet in an area where it cannot, but it should not crash like this.

I'm not really familiar on how to report bugs. This happens on both the 0.18xxx and 0.19xxx versions.

The maximum value for a fillet/chamfer is 0.1 mm. I confirm the program crashes with a larger value. This problem is known, there are a lot of threads about that in this forum

How do you enter a number?
I only know how to activate the chamfer or fillet command by first selecting the edge and then clicking on the fillet toolbutton. When I do this, FCad crashes. I have no chance to enter a radius number.

hi
as Willem says the problem comes from the connection between the cylinder, the cube and the 2 sides (see filet1 PGN)
my trick, recreated a compound object of 1 cylinder (0.1mm high) and a dimension cube from the inside, and make the filet, then add boolean

You can do this with a trick: Select a no-problem-edge to enter the fillet dialog. Change the radius to 0.1. Remove the edge and add the problem-edge.

Perhaps Willem knows a better way.

I agree that an instant crash is a bug. Confirmed here with same version as OP under Kubuntu 18.04.
Callstack at crash moment if it can help :
