Tangent Circle Tool Crashes Fusion With a Double Click

[liam]

When using the "Create Circle With Two Tangents" sketch tool, one can crash fusion with a double click, when common sketch geometry is present. If you have a square with all 4 corners radiused, and then double click on one of the straight lines with the tangent circle tool, Fusion immediately crashes.

To reproduce this, all you need to do is open a new sketch, create a square where all the corners are replaced with a curve,, be it a fillet or a spine, then double click on a straight line with the tangent circle sketch tool.

Attached is a picture of an example of the sketch geometry that can cause this crash.

When using the sketch tool "2-Tangent Circle " you are suppose to select two different lines, not double click on one.  If you execute the command correctly, it works perfectly.

Hey John

Yes, I do know that you are supposed to select two different lines - I do love that the tool works when used correctly.

It was during it's normal intended use that I stumbled across this bug.

My issue with it is that if you say, fumble with the mouse when sketching quickly, that you end up crashing your entire

Fusion 360 application. What I am asking is that whatever fusion is trying to calculate in this situation is suppressed/handled in such a way to not cause Fusion to crash.

If fusion can handle not crashing when applying constraints to a sketch that would break it/cause it to be over-constrained, I don't see how clicking a line twice causing a crash can be viewed as anything but a bug.

Many thanks for reporting this problem! Yes, it's very valuable for our development team to build the stable software. I can reproduce the crash and has logged an internal defect(ID: FUS-121789) to track it now. 

Thanks again！
