I drew nurbs curves in rhino and I am bringing them into Revit as directshape curves. I am hoping to use them to create native revit floors. But i get the following error:
In Revit, you can’t have the floor boundary curve to be a closed spline.
Option 1: You can split the curve into two segments before you add them as direct shape curves and then pick line on them.
Option 2: Use the add floor component in GH/RiR and it will do the above for you and create the floor.
