I’m aware of this topic
but…
When i create a new Revit file without using a Template and not Link a IFC file but Open it instead, a Shared Parameter File is also created.
If i then go back to my file with a Linked IFC file in it, and add the Shared Parameters as Project Parameters, i can create Filters and Color overrides based on those Parameters (Like IfcZoneName or IfcName and others).
question is:
How to do it using Dynamo
Hi,
as part of the organization of a challenge on the french forum I had shared this as a final solution
it might help you

OUT = ifcfilter
Maybe asking too much, runtime <> file size?
Sorry
I had it sketch out like this btw
-read xml
-find param
-copy
write as UTF8 txt file to create a Shared Parameter file
I don’t use the Shared Parameters file, I use directly IFC parameters generated in model (when Revit linking model)
The process is as follows
from the linked model
On the host model
