I am going to attempt to write a macro that aligns multiple parts to a single CAD reference file per the drawing data scheme.  I have two strategies that I am considering:

1. Create features on data_1, do an auto extract, plane/line/point alignment, then try to transfer the auto-extract option to data_2 and perform the alignment again.

2. Use an alignment for each datum, using ignore for alignment on non-datum surfaces and the best-fit alignment with specific constraints for each datum.

I am running into some dead ends with both options.  I dont know how to transfer the measured features from one data to the next.  Also I dont know how to automate the plane/line/point alignment very well.  For the second one, I am not sure how I am going to automate the constraints.  Maybe I could calculate the normal vector from the surface or something.

Can someone point me in the right direction if they have an experience with doing something like this.

Thanks in advance.

Inspector / Data Segmentation

Does anybody know how Data Segmentation actually works in the Best-Fit alignment?  The documentation has this:

QuoteA check box that, when set, specifies automatically detecting high-discrepancy
areas before computing a final accurate alignment. Otherwise, all
Data points are used in the alignment computations.

BUT, I am just a little curious how it determines the high-discrepancy areas.  The reason is, sometimes it looks like my datum surfaces are being considered "high-discrepancy" areas and are being ignored in the best-fit alignment.  Does anyone have a good rule of thumb with when to use this option or not?
