I haven't tried in VW 2022 though,

maybe something changed ?

 

In VW 2022,

most PIOs had already IFC 2.3 and 4 Tags.

Just Stairs did not have or not export even when applying IFC 4 Tags manually.

 

So it was mainly about applying IFC Tags to custom geometry.

If you applied IFC 2.3 Tags, there were no IFC 4 Tags.

And if you apply any IFC 4 Tag, that meant that VW switched into IFC 4 Mode.

So you can't even read your IFC 2.3 Tags anymore.

Until you do like you would want to apply a IFC 2.3 Tag again, this will switch VW

back to IFC 2.3 again. So your IFC 2.3 Tag should still be there to read.

Switching back to attach IFC 4 Tag will let you choose that Tag from the endless

lFC Tag's list again.

Rinse and repeat ....

 

I hope something changed until VW 2022 .....

but I had problems trying to collaborate with the IFC 4 output from VW and had to switch back to IFC 2x3.

 

Yes, here too.

But I thought IFC 4 would have some interesting new features, for Materials and such.

Maybe I should test IFC 4 again for compatibility and reliability.
