Before Landscapeforms had implemented all of their products into Revit, I had already created several Revit families myself. And since their families are import geometry, I decided that mine were still worth sharing.
The frame structure has been modeled beneath the shade.
It has materials for the frame and fabric, with all standard fabric colors included within the family’s materials. It also has the required type parameters for the Valance Edge and Surface Mount Stand, if not being supported by a table.
Like the real umbrella, it is designed to work with the Landscapeforms Tables, as shown below. And the umbrella displays as only symbolic lines in Plan view, so tables and chairs will still be visible beneath it, even in Hidden Line.
