Making roof editable

A roof was imported to Revit as a single uneditable element (I dont have info where from). It has a very complex shape with a lot of curve points. When I double click on it, there is no options to change anything other than “finish model” or “cancel model”. What are the ways to make it editable (to change pattern, etc.)
Is it through mass creation? If so how can it be done, since there would be needed millions of reference planes.
Is it through Dynamo/Grasshopper implementation? Thanks!


One way is to use Dynamo and remake it.
Then you’ll - somehow - need to get the lines and points of the roof before you can begin to change it.

Can you share the rvt. file with the roof?
