PMI - Is there Zeiss training?

[[Ri...]]

We may be getting into using PMI (Model Based Definition).

Is anyone using this?

Is there a STEP AP242 model available for training?

Pros

Cons

Does Zeiss offer training?

Hi Richard,

There is a PMI eLearning available. 

Learning Content:

• Identify basic requirements needed to create a PMI measurement plan
• Create measurement plans using PMI in ZEISS CALYPSO.
• Apply dimensional, form and location tolerances on a PMI program

I believe I was able to play around with PMI on the Zeiss Cad Cube model if you have that.

The biggest problems I have with MBD is that you're relying on someone else to put the correct callouts on the model and you usually have to modify any auto-created feature strategies anyway. But then it's been a while since I've looked back into the technology.

No STEP242 version available, but you can use the cadcube_PMI-named.sat file.

First draw back I see that you can't rename the PMI entities prior to creation.

Zeiss should add a dialog box to enter the characteristic name prior to creating the characteristic.

The pmiData.pmi file appears to be an xml file.

I can edit the PMI file and rename characteristic names, not sure of the effect on tolerances and related features/characteristics yet.

Don't mind my ramblings, I am searching for methods of characteristic creation that follows my characteristic naming scheme.

A CAD converter is required to read CAD models that contain PMI data. A direct interface such as CALYPSO CATIA V5/V6 or CALYPSO CREO (depending on the database) is recommended. The CALYPSO STEP interface is now also possible (from version 2021). However, data information is often lost when reading in via the STEP interface.

 

I only have Calypso 2020 💩 so I can´t use this tool.

Hi all,

there is also a free webinar: PMI in metrology 

It is not software specific and should give you a good idea of the whole process.

Renaming the features makes no sense as it destroys the traceability in the MBD process.

And also a whitepaper is available for you to download.

And for Creo Designers we offer a CAD training for MBD as well

It makes a lot of sense when you go from reports like mine, to reports that could come from a PMI part.

Then maybe, if PMI becomes more important, a naming convention could be agreed on, so that there's no difference between the reporting and the naming in the PMI file.

Nevertheless all customers that I've spoken with want to keep the traceability therefore they either use the naming that comes automatically when you create features in the CAD-software or they have special naming schemes defined in design and metrology so that no changes are required. Ideas for such a scheme can be taken out of ISO 7499 and ISO 7533

Hope that helps.

Best regards
