I have profile of a surface called out to these datums.
I tried two alignments:
- One alignment uses cylinders. I autoaligned to the top plane and the 2 cylinders.
- The other alignment I created a 2d best fit line between the cylinders. I autoaligned to the top plane, the best fit line, and one cylinder as my tertiary datum.
My profile of a surface looks crooked when I use the first alignment, and it looks much better using the second alignment. Can someone explain why my results would be different? Should I go with alignment #2? Please see screenshots.
