Interesting thread and thanks for the script Michael!

I am wondering about the following, regarding those dense control points
in the letters. Because MoI does not use Bezier curves like Illustrator what
would happen for example if one loads those Bezier curves for example into
ViaCAD (which I no longer have) and then change in there the Curve type
to what MoI likes and then export and import into MoI.

Would that get rid of the many control points?

Stefan

Beziers are a subset of NURBS, so MoI can import a Bezier curve drawing from 2D illustration programs exactly.

Going the reverse direction can be more problematic - it is possible to break a NURBS curve into a chain of Bezier curves with the exact same shape, but if the NURBS curve uses rational control points (which will be the case for conics like circles, ellipses, ...) then you get a chain of rational beziers while the illustration formats only support non-rational beziers. So in that case there has to be a rebuilt curve exported instead of the exact curve.

But on the other direction there isn't any refitting, if there are a lot of points then that's just what was in the file.

If it did it would involve changing the shape by some amount.

I send files for Cutting to an industrial laser and they run JETCAM and PEP Technology on their machines. Prior to creating a cutting path NC file both programs will highlight problem areas they put a circle highlighting flipped or duplicate points on a curve. They are both high end applications each seat costing thousands of dollars a year - So this solution offers the same result in a very elegant manor. I havent seen any auto repair tools out there as the coding to work out the scenarios for the errors would be highly complex. But once again MOI offers a simple solution to a common problem. Instead chasing countless points highlighting dense areas is usually a good starting point to a problem leaving the user to decide the best manor for clean up.

Thanks again.
