Number of points will affect the accuracy?
But in this show number of samples 50 points radius of 3.
This show number of samples 1 points radius of 3.
PhoeNX has correctly stated that the number of samples are the sample points taken on each face.
Yes the accuracy will increase with sample points.
I am attaching an image herewith. You can see that i also get a simmilar result as you by specifying only 1 sample point .But if you do a curvature analysis of the transition blend area then you will find it is not of a constant radius (infact there are very few points on it with the same radius as the other two faces). So when i chose 1 sample point it took the sample point only on that region and includes the 3 rd (transition area) also in the list which is not ok as it is not of a uniform radius value but the FACE RADIUS LIST still shows it with a constant radius as the other two faces so the one with 50 sample points is the accurate one.
Thanks and Best Regards
