Iterative aln. plane pnts

[Jeffrey Lovely]

When you create an iterative alignment
and you are selecting more than 3 points to set the plane
lets say 9 hits ,three for each 20 mm net dia and on 3 seperate planes
or 3 nets on an even plane
What are the exact 3 points that will be used to create this leveling plane?

is this working?

This doesn't really answer the question posed but I thought I'd answer anyways. Too much information isn't a bad thing it just gives you alternatives.
I don't have any experience fixturing w/nets(by the way what do these net thingies look like, anyone?)...but I'll throw in my idea anyways. What if you took each of the 3 sets of 3 points and made 1 point from each set? Then you have the average vector from each net plane in just three points, and then from there you can use those 3 points to set your level. Sound viable?

When you use more than 3 points to level it tries to average the deviation of all the hits,(Best fit). One option is to do a max array of three hits on each net after the initial alignment and create a generic point with it's values, doing this for all three nets gives you three points that should represent the "Highest" point for each net. Use these three points to level to in another iterative alignment.
