SketchArc - blue screen

Hi TF360,

This is a copy of the crash report just sent to Autodesk.

############

Silly me, I have tried create 3PntArc when the firsts and the last point have the same coords. Such situation ends (predictably) in this 'blue screen' report.
How difficult could be to fix it?
Regards

It certainly shouldn't cause Fusion to crash (I assume that's what you mean by "blue screen"). But it should fail because having two identical points doesn't provide enough information to create the arc.

Thank you for the light speed response Mr.Ekins,

crashes for points A <x:-2.25 y:-1.5 z:0.0< C <x:-2.25 y:1.5 z:0.0> E <x:-2.25 y:0.0 z:0.0>

in the code line arc_A = Arcs.addByThreePoints(point_A, point_E.geometry, point_C)

I have dag deeper. Obviously this is MY PROBLEM. SILLY ME.

However, the software should handle such issues in more more graceful way.

Agreed. It should raise an exception so you can catch it with a try except and should never crash Fusion. Crashing is definitely a bug on the Fusion side. Providing bad input is a bug on your side.
