Each of the methods below has its advantages and disadvantages.
Rhino to revit roof.
Extract plan export a 2d dwg floor plan from your revit model for reference in rhino.
Start a new revit project.
There are many ways to pass models and objects between rhino and revit.
Click on the zoom extents icon in rhino to find the roof geometry.
As a project matures it becomes necessary to export the rhino models into revit for further refinement and documentation.
Save the family with a suitable name.
Check the units in rhino under tools options then either import or insert the dwg plan as a reference.
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.
This will activate and import the roof geometry on a layer in rhino called roof.
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 sat file will then load into the family.
See hd version of video tutorial here.
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.
These elements will be hosted to the rhino geometry.
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.
Import the sat file centre to centre.
In this case rhino is not used as an intermediary.
Creating a revit directshape roof.
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.
Make sure you set the scaling units so that the imported file scale is the same as the rhino file.
Of course with a little more work that roof could be a roof from boundary and create a roof system family.
Sample revit to rhino gh grasshopper definition for this example.
Finally in revit architecture we can load the mass family geometry into a project and associate building elements walls floors to the rhino geometry document the design and quantify.
The surface is then used to create a roof in revit.
By enabling the directshape component in the grasshopper canvas grasshopper will then create a roof based on the lofted surface from grasshopper.
A common workflow is to use rhino for early design and model exploration.
