I noticed random behavior when trimming arcs in a sketch and think this is a bug.
When trimming 2 intersecting arcs the trimming fails when the endpoint of one arc is coincident with the second arc. Moreover the trimming cannot be undone.
To reproduce open the attached file:
and trim the upper ends of the arcs so that only one arc segment would be left. The interesting thing is that the result cannot be foreseen and that in all cases the trimming cannot be undone.
Here is one try:
but sometimes I end up with 2 arc segments not intersecting each other but being connected in one point.
So am I doing something wrong or is it a bug?
