Model Group Parameters RVT 2018

[Anonymous]

I was under the impression that in 2018 we could attach shared parameters to model groups. But my addin still seems to have problems with attachting parameters to model groups.

Because of this i had to revert to the previouse solution:

Is there anyone who can confirm that we still can not add the OST_IOSModelGroups to the categoryset when assigning parameters.

Dear Michael,

I am not aware of any changes regarding this in Revit 2018.

Where did you get that impression from?

Cheers,

Jeremy

Additionally, we now have in the UI the option to select a Model Group when assiging parameters to the document.

Aha.

I don't immediately see the connection...

Anyway:

I explained how to determine how to add a shared parameter to a new element type here:

Oops, that includes model groups...  🙂

Check the blog, man!

Right, so that's what im referring to.

When wanting to add a parameter in previouse version, we had to do the "loading of a model group first" trick. But now that it has been added to 2018, i tought we could just add the model group category to the categoryset when creating the parameter. Guess i was wrong.
