Summary	0003938: Polar Pattern "transformed shapes do not intersect support" (upstream OCC bug)
Description	As discussed on the forum here, there is a bug when using polar pattern if features are lined up just wrong. I tried using polar pattern of Grooves on a Revolved solid and get "transformed shapes do not intersect support". Selecting different numbers of occurrences get different array elements working, but never all of them. As mentioned by forum member kisolre, We again hit some OCC coplanar/colinear/co_something issue. Moving the center of the arc some distance away from the edge of the base coin fixes the issue (see the 0.1mm dimension). kisolre kisolre provides a good screenshot of the "fix" to get around the bug in the forum thread.
Steps To Reproduce	Open the attached file. Edit the ScallopPolarPattern and see the preview. (Also see my screenshot on my forum OP.) Change the number of Occurrences and see the preview. To get around this: Open the ScallopSketch to edit. On the horizontal construction line remove the horizontal constraint. Add a vertical distance constraint between the two endpoints of the horizontal construction line. Set that vertical distance constraint to a non-zero number. Close the sketch and see on the object that all the Grooves are now properly patterned around the disk.
