Hi Burr,

No, there is not any setting for that.

There is a value used for certain operations that need to be approximated, like when the intersection between 2 surfaces is calculated, that intersection is calculated to an accuracy of 0.001 units.

But that "fitting tolerance" value will not come into play at all when drawing a sphere, that should be precise to a much greater amount than just 3 digits, more like 13 digits or around there.


Do you happen to be creating the ball a large distance away from the 0,0 origin spot?


Other than that, I'm not sure what is happening in BobCAD. Can you do a test of trying to export a 5 inch ball created in BobCAD and see if it comes back into BobCAD as 5 inches or if it also gets reported as a different size?
