Rhino To Revit Roof

Save the family with a suitable name.

Rhino to revit roof.

Grasshopper is launched directly from revit. Of course with a little more work that roof could be a roof from boundary and create a roof system family. This will activate and import the roof geometry on a layer in rhino called roof. Extract plan export a 2d dwg floor plan from your revit model for reference in rhino.

Click on the zoom extents icon in rhino to find the roof geometry. By enabling the directshape component in the grasshopper canvas grasshopper will then create a roof based on the lofted surface from grasshopper. This sample shows how to take revit objects into rhino. The sat file will then load into the family.

Depending on the base geometry revit may make editing the mass accessible via grips push pull arrows but this is not always the case. Therefore if the rhino file was created in metres make sure the import units are set to metres. This will set the view so you can see the rest of the. Import the sat file centre to centre.

Each of the methods below has its advantages and disadvantages. In this case rhino is not used as an intermediary. A common workflow is to use rhino for early design and model exploration. Start a new revit project.

See hd version of video tutorial here. The geometry from rhino can be used in revit architecture the image below is a exported sat file from rhino inserted into a revit mass family template. There are many ways to pass models and objects between rhino and revit. Make sure you set the scaling units so that the imported file scale is the same as the rhino file.

Creating a revit directshape roof. Sample revit to rhino gh grasshopper definition for this example. Check the units in rhino under tools options then either import or insert the dwg plan as a reference. 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.

These elements will be hosted to the rhino geometry. 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. The surface is then used to create a roof in revit.
