Hi, I want to ask how is possible to create a script that cut walls from structural framing and columns in Str linked file?

You can use InterferenceCheckReport from Revit in Dynamo and transform Revit geometries to Dynamo geometry to find intersections. Then you can bake the intersection part of Dynamo geometries to Revit as a void. Finally, you can cut void elements with wall elements.

I hope this will be helpful!
