Hi Burr, that kind of requires a level of processing that's beyond what a script is good at doing.

It's something that is possible to add in the future but the function for it would really need to be added as some core c++ code, it's not really suited for fully implementing the entire process in script.

But Rhino has a CrvDeviation command that sounds like it will do what he wants here, I think even the trial version of Rhino would work fine for that particular purpose. If you set the "keep marks" option in Rhino it will generate points and a line at the min and max deviation spots and you can select a point and use the "what" command to get its x,y,z coordinate, so you don't really even need to use up a save for getting that particular information.

Doing that should get the job done right now I would think.
