Auto-Cylinder vs Circles Constructing a Cylinder: For Perpendicularity

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

Glad to know that i'm doing this right, what exactly is Cir1.hit[1..numhits]? some sort of array?

its a method to force pcdmis to include all individual points in whatever you are intending to use it within. In this example, if you created the circle feature using autofeatures, then call the circle to construct an axis line or a cylinder, it will only pull the autocircle's centroid point. you can use the cir1.hit[1..numhits] to get away from the centroid, and instead it would use all the point data that is being measured in that autofeature
