Creating sloped building pads from mesh

Revit
, ,
1

Hi guys,

I’d like to create a sloped building pad from a generated mesh or solid in dynamo/revit.
Is there any way to create a building pad by using the outline of a surface?

I’m able to split the solid up into its surfaces, but I didn’t find a solution to create a building pad out of the surfaces.
After that I’d like to automatically draw the tilt-arrow to the building pad in order to have the pad tilted.

Thanks francois! But unfortunately thats Not quite what i wanted to achieve. I like to convert the sides of my solid to building pads.
