Thanks, Martin, for your attention.
Do you think what I did in the image is correct? Or is there another way?
Is there a specific command for the common zone?

Make sure to choose the correct method

Least Square or Gauss Best Fit  (LSQ-2D-Best-Fit):

This method calculates the average best fit pattern such that the sum of the distances squared between a calculated (ideal) position and the actual position is at a minimum. Each element of the pattern carries equal weight in determining the position and orientation of the pattern center.  

Good analytical method for dialing in a machining process but not for inspecting a part for functional fit.

L1 Best Fit (L1-2D-Best Fit):

This method is similar to the Least Square or Gauss Best Fit but is less influenced by outliers and has proven to yield better results for dialing in a machining process.  Again also not for inspecting a part for functional fit.

 

Minimum Error Best Fit (Tschebyscheff/Minimum-2D-Best-Fit):

This methods calculates a pattern such that the smallest maximum deviation occurs between an element’s calculated (ideal) position and it’s actual position.  It wants to minimize error for all elements regardless of the reference features. Outliers have a greater impact upon the result.

Note:   The Tschebysceff algorithm used here may not catch every opportunity but will never pass a bad part.

 

View Tolerance Best Fit (Tolerance-2D-Best-Fit):

Uses an iterative method to most closely simulate a Go/No Go gage. Called  “Tolerance” Best Fit because its’ goal is to iterate all elements into tolerance, if possible. This is the best option for inspecting a part for functional fit and what is generally recommend for functional checks.
