I bought a JT to PowerMill converter a month ago. so now I can see the PMIs in our CAM software (PowerMill from DELCAM). it is visible and usefull for the CAM guy.
But all PMIs are converted to wireframe types, which is annoying - but I put it on a seperate level/layer.
And we still dont have a implemented way to put PMIs on - So we are probably at the same stage as many of you are.
A colleague is working on Zeiss Calypso - he says he can import the JT. and is working on the PMIs.
Here you can see the PMIs in PowerMill.
We have not tested the Calypso from .jt translation yet but what I have discovered in working with them is they can not read any other views in a native NX database other than canned views. I have sent them a few files (finally a very simple one) and continuously was being told they couldn't see anything. After a WebEx meeting I discovered that Calypso couldn't read/find any of the other views in the database. We have created standards unitizing MIL-STD 31000-A and ASME Y14.41 2012 where we put all of our PMI in views named MBDX-XX. PCDMIS on the other hand can read the files. At this point I think Calypso has a long way to go.
