During geometry creation of a curved slot I have found that sometimes when connecting the geometry the arc at the end of the slot is inverted from what I want. I am using GibbsCAM 7.3. Basically I create two circles that form the inner and outer walls of the curved slot. Then I create two lines that radiate from the center point of the previous circles for where the the slot ends. At the ends I then create circles the same diameter as the slot is wide. Then when I go to connect it all sometimes one of the end circles is inverted. I can't seem to find a way in GibbsCAM to make it choose the other side of the circle. I have used SmartCAM and MasterCAM and there is a way to choose which solution you want, but with GibbsCAM it seems random and uncontrollable.
Thanks
