Auto-Cylinder vs Circles Constructing a Cylinder: For Perpendicularity

cmmGrum
Which is more accurate, the auto-cylinder to plane OR 3 auto-circles (constructing a best fit, least squared, cylinder) to plane.

Essentially they should have the same result, correct?

When I run it I have a 0.0009 difference between the results.

Which number should I trust?

(I am building off of an IGES file)

Looking at previous posts I made sure that I had it set to Perp to Datum

  • the constructed cylinder can be constructed incorrectly, by only using the centroids of each circular cut. In order to have them judged the same, you'd need to use Cir1.hit[1..numhits] in the constructed cylinder. this would then utilize the individual points of each circle cut to construct your cylinder, and then they should be a perfect match.
