To Create a Best Fit Circle
By using the Best Fit option, you can create a Constructed Circle through several points. You must select at least three points (or entities that represent points). If you select more than three points, the system constructs the circle that provides the best fit for all the selected points.
1. Click Inspect > Circle. 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.
