How do you drape an aerial in Openroads Designer Connect Edition?

I feel like there should be a simple solution to this... but how do you drape an aerial to the triangles in a file? I tried bringing in my aerials through reference manager and changing the Draping option to yes and still doesn't work. I am using an aerial that is not from google earth. Does that matter? I would hope not.. Current version we're running is 2020 R3
