I have been driving myself batty trying to figure out why I can’t get the pieces of my model to align when I assemble them. I think I have discovered a problem in SU. What do you think?
The model is @ x1000. dia = 136000mm.
the error circle is shown at the same scale.
So it is about 0.06% but enough that my top an bottom do not match up.
What I will try, as a work around, is to get the axis of everything aligned so that I do not have to rotate anything to assemble it. I thought I already tried that but I just tried too many things.
Also the first time I tried to document this the error circle was only 58mm dia. No idea why it increased
Also, I think the first time I did it the 180° rotation axis was on the error circle. This time it is way off.
the following pics are annotated.
bottom center 1 - axis aligned with center of model
bottom center 2 - same view after 90° clockwise (from bottom view) rotation
bottom center 3 - same view after 180° clockwise (from bottom view) rotation
bottom center 4 - same view after 270° clockwise (from bottom view) rotation
