thanks, really appreciate your answer

but, I still have some questions:

1. the 4th axis digitizing wizard output is in polar coordinates. I convert this output in Cartesian coordinates. But... the ball conversion... should be do it for Cartesian coordinates. Is this correct?

2. can you give me more details about "max angle" setting? By default is 1.57.  Shortest edge (0.5 by default) is clear, I think, should be the shortest straight edge on the digitized model. but the max angle, is not very clear for me, especially for 4th axis digitizing tasks

and... if you know.... there are any other application which can do this ball conversion?

kind regards,
Seb

Seb:

  All data should be in cartesion coordinates. The ball method basically rolls a ball bearing of whatever size you dictate across the points. Whenever the ball rests
on 3 points, that creates a triangle for the output. If the angle between any points are higher than the max angle, it is ignored. This helps for some situations
when the ball doesnt quite sit properly on those points.

 Im not sure how many app's are out that do this, it was a theory expressed in a papaer I read, so I write a routine to do it... Seems to work well
under many situations, but I havent used it in years so I cant advise much on how best to use it anymore. :)
