"Default" Math Vs "Legacy"?

Cumofogabriel
What are we calling the new default Geo-Tol math? "New Math"? "Default Math"?
I remember this gun fight a loooong time ago, it ended up bad for Hexagon and us also.
what I mean is:
The "New Math" best fits a little too aggressive for me compared to "Legacy". Last time I had reports coming out with perfect true position our customer Lockheed Martin mopped the floor with Pc-Dmis and started the whole ISO Best-Fit shootout, disallowing us to use Pc-Dmis best fit algorithms. The "New Math" best fits also. Here is a comparison:



What do you think?
and can we come up with a disparaging term like "New Math" other than "Geo-Tol"? or "Geo out-of Tol"?

thx

    Really good practical tests and applications: there is a difference between theory and practice!

    Thanks NEIL! :Those constructions are not necessary when working with the geometric tolerance command because it performs the constrained L2 calculation automatically in the background when you have DEFAULT datum math and DEFAULT feature math selected. As you are seeing, when working with the geometric tolerance command, most constructions are unnecessary and can actually get in the way.

    I thought it was memory leaks or a runaway script infecting legacy with "New Math". I know it changed, and now I now it was intentional. Thats mvaluable info


    I like the Calypso flavor . I think the new MIN/MAX with two separate centroids is valuable, I would like to see the diameter (a size feature) re-comped around and origin that was passed through a roundness style filter as a confidence check

    with centroid of FORM (Roundess), centroid of MIN /CIR, CENTROID of MAX CIRC
