Region Union skips vertices

Hello,

when using region union I encountered this problem:

Some vertices of the polygons dont seem to register when combining the regions, altering my geometry. Has anybody an explanation or a solution for this problem?

I think this is a tolerance problem. Scaling your curves might help.

Thx Martin,
this fixes the problem. I read about that before on some other post but didnt see how this would help in my case. So if anybody else has the same problem this is how I did it:

scale everything with 1000 → do the Region Union operation → scale it down again (1/1000)
