To Create a Best Fit Plane
By using the Best Fit option, you can create a Constructed Plane through several points. You have to select at least three points (or entities that represent points). If you select more than three points, the system constructs the plane that provides the best fit for all the selected points.
1. Click Inspect > Plane. The CMM Construct tab opens.
2. Select the parent reference Csys from the Parent Csys drop-down list.
3. Select Best Fit from the Type drop-down list.
4. Select 3 or more measure or construct steps of the following types:
Point
Circle (center)
Cone (cone vertex)
Sphere (center)
5. Click OK.
