Node FamilyInstance.ByGeometry from spring node

no cause it still doesn’t work

In Revit start a new family from the template and show the materials which are available.

@jacob.small i already told you. those :

But you also said this:

Which indicates that you generated a new version of your family template after creating all of the materials.

Add the materials into the new family document, save it as a new family called massing template.rfa, and then in a file browser change the extension from to massing template.rft. Then use massing template.rft as your template file for the springs node.

@jacob.small that was for the blue one

okay i’ll try this method and i come back to you

@jacob.small Nothing appened … still the same situation

Provide your family template and a graph to recreate the issue.

this is my familly template : Autodesk Drive
Wich graph do you want ? @jacob.small

Just a simple .dyn created to be run in a standard project template that causes the issue to reproduce. Say applying ‘blue’ to a cuboid.

@jacob.small Autodesk Drive

@jacob.small look at this video, this is my method and my result : Autodesk Drive

I open my .rft file, which I created with the new materials. I run my script, which creates the different masses (with materials) in my family. I close my family and reconnect the FamilyInstance.ByGeometry node (because it’s not possible to do this in a family), then run the script. The result is visible. I’ve got all my families in the tree structure , but they’re all the same color…

@jacob.small After viewing, do you have any idea how to do it?

Do u think is it possible because my solid is a void ? cause in the script, the autor told that it’s impossible to put material if the solid is void …
