The Advanced Best-Fit Options dialog provides some advanced, less commonly-used settings for best fit transformations.
■ Advanced Settings. Displays the Advanced Best-Fit Options dialog, discussed below.
Descriptions of these parameters follow:
Reset transform and scale before each re-fit. The transformation is solved from the same initial starting position and orientation each time the fit is performed. This is the default and is applicable to most fitting operations.
Apply transformations successively. Each fit operation solves using the previous calculated transformation as a starting point. This allows you to apply iterative best-fit operations with different degree of freedom settings for each. For instance, you might wish to first solve the best-fit with some degrees of freedom locked, then solve again from that position with a different set of locked degrees of freedom.
Reset Transformation and Scale Now. Resets the current transformation back to the “starting point”.
Store weight settings with points. Fit weights can be stored with nominal or actual points such that if the points are used in another best-fit operation, the weights are recalled.
Make a new group when fit is finished. Makes a copy of the reference (non-moving) points and puts them into a separate group with the specified name at the completion of the operation. If nominal coordinates were changed in the Best Fit Item dialog, this group will use those updated coordinates. This is not a common need.
