Ammo: Cutting Objects to Topography

I've worked with Revit as a modeling tool for quite some time now and every now and then I face the need to cut objects with a topography. This is typically dam constructions or other objects that need to fit to a rock surface.

I haven't been very thorough in my research online within the native Revit enviroment but as far as I can tell there aren't that many options, if any.

So naturally I have been searching for a solution with Dynamo, but so far it has been to no avail.

Until now that is.

Enter Dimitar Venkov's spring nodes.

Dimitar wonderful collection of nodes has been extended with a particularly useful node, the "FamilyInstance.ByGeometry"

By providing a family template file, category, name and the geometry itself it generates a family of whatever geometry you fancy. (With the disclaimer that his node is in beta. And Dynamo is beta.. and.. just try it.)

Couldn't quite get it to work with generating the family as a void, but that's a quick fix and nothing compared to the advantages this tool gives us.

The result in Revit:

And a quick youtube video, Enjoy!
