I have a suggestion regarding the profile evaluation with a datum:
Add a math selector of the tolerance zone when evaluating a profile with a datum (line or surface).
At the moment it automatically uses the "Default" math. It should be possible to use the "LSQ" math.
When evaluating a profile without datum this is already possible.
Reasons for the suggestion:
- Default math will still be available (to evaluate according to the standard)
- With "LSQ" math, one can better see the general form of the part, outliers are clearly identified
- "LSQ" math gives more repeatable results (better for MSA)
I understand that the "Default" math is the one we should use to measure according to the standard,
but it can be difficult to understand the result it delivers. "LSQ" math gives easier to understand results witch is crucial to adjust the machine.
See this example:
I submitted the suggestion also to the idea center:
