Is there a diameter size limitation on a circle used for a helix. I am looking for minimum size. Trying to model a drill bit but helix won't recognize circle of size .1555, thanks.
Whatever it is, it is much smaller than .1555 inches (or millimieters). SW can (sort-of) go down to microns.
Can you upload the part file you are having problems with? Include a quick description of where you want the circle to go? There may be some awkard geometry that is prohibiting that particular size, but it would be tough to say without seeing it.
What units are you in?
