Hello there! I think I´m experiecinga such a bizarre issue in Sketchup.
I have some circles drawn one “inside” other over a flat face, but I´m not being able to select only one face between the circles, because it selects all the faces at the same time (even the faces that are over the limit of the lines), as shown above:
This if the original SKP file. PrizeKJJ.skp (1.2 MB)
Does anybody has any idea about what´s going on here?
