Does not draw or add family to the imported SAT file

Good morning I’m trying to make a script where I import a surface to turn it into massa and give it a floor type family. Dynamo calculates it without any error but you don’t see anything in Revit (I have turned on mass display and unsuccessfully). Thank you and a greeting

Look at the color of the Mass.BySolid Node. It is missing an input, the Material one.

Good morning I have the following mistake, someone can help me.

Hey,

I don’t have that node, not sure why! I use Springs Package for importing geometries, hopefully if you look at this example it will help you…

Given the look of your graph, I suggest you maybe have a look at the Dynamo Primer… https://primer.dynamobim.org/04_The-Building-Blocks-of-Programs/4-4_strings.html

Hope that helps,

Mark
