Does anyone have a STEP or QIF practice cad file with Model Based Definition I can play around with? Thanks

Look in your CAD folder (C:\Users\Public\Documents\Hexagon\PC-DMIS\version\CAD).  There should be a couple of Hexblock models...

HexMI_DemoBlock_Large_PMI_Inch.CAD

HexMI_DemoBlock_Large_PMI_mm.CAD

HexMI_DemoBlock_Small_PMI_Inch.CAD

HexMI_DemoBlock_Small_PMI_mm.CAD

.

There is also a LeicaDemoTool.CATPart model containing PMI but you need a Catia license to open it.

From 2023.2 onwards we also include a HexMI_DemoBlock_Small.qif model with PMI but, again, you need a QIF license to open it.

I have bad experience using STEP with PMI and I can clearly say - IT'S NOT WORKING AT ALL. TOTALY USELESS. Maybe it's working well with demo block from hexagon, but that's all. When you import other model with mbd Pc-dmis will try to create features but can't use it at all. It's good idea but it's not working yet.

Robert Hulman  Have you checked the CAD Information dialog to confirm everything is associated correctly?  The majority of PMI problems we encounter are due to things being incorrectly defined or incorrectly associated in the native CAD package.  When it comes to STEP, there is also the added factor of translation when exporting from the native format to STEP.

Also, what version of PC-DMIS are you using?  We have made many improvements in recent versions - try signing up to the 2024.2  PC-DMIS Technical Preview  to see the latest improvements.

Of course I did. I use STEP AP242 only with semantic PMI. All annotations are linked to CAD. I'm using version 2024.1 SP2. And another dangerous issue occurs when i run program which contains native PMI through Inspect. There's a big bug which can lead into machine equipment damage. Damage of wrist-head or probe because unexpected collisions but it' another story.
