No @Kulkul , what I am triyining to do is create like a topography inside the big volume.
So at the end i will do a wall by face to the volume and the solid generate with dynamo in this case will be like my floor.
i am using a lot your nodes couse i am triying to create some geometry inside those volumes, and for that revit is sometimes very hard to cut complex geometry, dynamo allows me to do it easier but without your node i cant do a section to all of them .
Here u see some geometries where i am triying to do something similar, have those elements inside my big volumes. I know that this is very strange, is for a project in the university jejejeje
