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

  • , how do you use Cir1.hit[1..numhits]? I'm using basic circle scans to construct circles along a cylinder. Then I'm constructing a cylinder using the circle constructions I made to get an overall dimension. Would using Cir1.hit[1..numhits] make the constructed cylinder more accurate?

    In the case of basc scans, the constructed feature uses the hits directly.
    For an autofeature using scanning options, the centroid can be used by default (in this case, you can create an axis)
