Beta GD&T Engine

[[To...]]

I'm starting to play around with the Beta GD&T Engine in Calypso 7.8.08, in particular the GDT Position of several cylinders with Simultaneous Requirement.  Setting up the SimReq is not the issue.  However, trying to find an efficient way to set up the evaluations per ASME Y14.5 is where I need some help.  Please feel free to correct me on any of my statements. 

First off, the settings in Extras > Measurement > Form Datum, i.e. Outer Tangential for new Datums, or Ref Calculation per ISO 5459 do not pertain to the Beta Version.  In other words, the evaluations on Datum Features come in as "Suggestion".  What does this even mean?  You need to convert every datum feature to Outer Tangential or the proper inscribed or circumscribed evaluation (there is no OTE option for cylinders).  Even the considered feature, should be evaluated using OTE.  What does the "Point Separation" option do?   

The secondary and tertiary datum features also come in with "no constraints" and there is no option to activate them.  Does that mean that Calypso automatically applies the constraint rules of ASME?  Would it not make sense for Calypso to automatically apply all of the proper evaluations and constraints to meet ASME?  Having to check each and every option and setting WASTES time and money.  If there are settings that take of this, I'd appreciate someone pointing this out for me.

 

Below are some minor oddities.

The options for setting RFS/MMC/LMC and Projection is blank (or not showing any default Default, i.e. RFS).  The same applies for a datum feature of size and the options are MMR and LMR.  What is MMR?

Nice catch Tom,  I've been using the beta since it came out now and did NOT notice that.

Wow, yeah, interesting stuff, seems GDT Beta Engine has a long way to go in my opinion.

 

 I understand GDT is not easy to begin with and to math it all out is more of a challenge, but yeah I think they should be a bit more advanced than where they are, other softwares are I believe.

 

It's coming along, we just have to have patience I suppose.

 

MMR = Max Mat'l Requirement ?   I believe that is ISO 1101 - never heard it in ASME Y14.5
