** Revit File link (only 3 compomenets in revit for simplicity)** I have 4000 generic model components in a Revit file. Those components are coming from IFC. I need to assign different materials to these components according to the time schedule. The time schedule will change often, so if I do it …

I haven’t used Dynamo to collect IFC elements, but I assume you have converted the IFC into Revit geometry, which in turn converted the columns into in-place generic models. If there is anything these columns all have in common (such as a name or parameter), you could collect all elements in an act…

Hi GavC Thank you for the detailed solution. Unfortunately, 4000 ifc elements have different geometry, not just column as shown in attced rvt file.

Sounds like a fun one… crank out the elbow grease I guess. You could try to at least handle the more regular elements using scripting with simpler geometry (maybe by converting to geometry, converting that to polysurface, and filtering out anything with more than 6 surfaces?).

I found this Model-in-Place component convert to Family component . But it seems like I have to manully convert each element.

I can create a “material” shared paramter and project paramter and link them together. In revit edit in-place mode, I can assign the shared parameter to element. Then I can assign required material in the project parameter. I have to do this 4000 times in revit. The problem is how to assign the…

[image] Xiaofei_Ying: how to add material to the generic model family template? If I have 4000 ifc elements, do I need to do the above work manully 4000 times? Hey, So create a family from template, add the materials, save the family and rename to .RFT. My thought is that hopefully when IF…

Hi Mark.Ackerley The attached is a simplified version, not 4000 components. change extension rvt to ifc. rhino .rvt (32.7 KB)

So if you update this part here? [image] With a template that has your desired materials? Does that work for you? :slight_smile:

Hi Mark.Ackerley I create a family using generic model.rft and apply “Default” material, then save it as Family1.rft. How do I use it to import IFC, sorry for the ignorance. Change ext from rvt to rft. Family1.rvt (344 KB)

Specify Family1.rft as the ‘Default Template for IFC Import’ (as above) and see if it works?

Sorry, dead end

Perhaps Geometry Gym can fly to the rescue?!
