Rhino to revit rvt revit model for the sample.
Rhino to revit roof.
Of course with a little more work that roof could be a roof from boundary and create a roof system family.
Click on the zoom extents icon in rhino to find the roof geometry.
Exporting elements from rhino so you can import useful shapes into revit.
Rhino office 3dm rhino model containing the source building model.
This will activate and import the roof geometry on a layer in rhino called roof.
See hd version of video tutorial here.
Bringing across the model.
This will set the view so you can see the rest of the transfers.
These elements will be hosted to the rhino geometry.
Creating a revit directshape roof.
In this case rhino is not used as an intermediary.
Rhino to revit gh grasshopper definition for the sample.
However the best method to generate native revit elements from rhino is to use the wall by face roof by face curtain system and or mass floors commands.
This sample shows how to take normal rhino breps curves and points into revit.
Grasshopper is launched directly from revit.
By enabling the directshape component in the grasshopper canvas grasshopper will then create a roof based on the lofted surface from grasshopper.
Depending on the base geometry revit may make editing the mass accessible via grips push pull arrows but this is not always the case.
The simple script that is shown calls for the selection of two revit edges and it uses them to create a geometrical surface by lofting them.
