Hey everyone, we currently use a 3D Circle Fit LISP in C3D2016 to report on surveyed flange faces, but have noticed that since we modified our template unit settings to read clockwise from north, the circle fit routine no longers functions as expected and draws the circle at the correct size, but at a seemingly random angle.
I'm not sure where this file came from as it's not included in the code, can't be found online anymore and outdates any of the CAD staff working for us. It's quite possible this file was developed in-house, as we've got other older programs there were written in-house.
If someone could please take a look and see if they can see what would be causing it; or even point us to a different circle fit LISP, it would be much appreciated. I can't see what would be casuing it, as I'm not aware of a connection between the angular units settings and UCS, and it seems like this program just draws multiple circles at various UCS to fit each 3 point circle, then averages those circles out to get the best fit circle.
