Import the sat file centre to centre.
Rhino to revit roof.
In this case rhino is not used as an intermediary.
Each of the methods below has its advantages and disadvantages.
A common workflow is to use rhino for early design and model exploration.
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.
Make sure you set the scaling units so that the imported file scale is the same as the rhino file.
This will set the view so you can see the rest of the.
Creating a revit directshape roof.
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.
This sample shows how to take revit objects into rhino.
Start a new revit project.
Sample revit to rhino gh grasshopper definition for this example.
The surface is then used to create a roof in revit.
Save the family with a suitable name.
There are many ways to pass models and objects between rhino and revit.
Extract plan export a 2d dwg floor plan from your revit model for reference in rhino.
By enabling the directshape component in the grasshopper canvas grasshopper will then create a roof based on the lofted surface from grasshopper.
You can export a 2d dwg but be careful when importing 3d dwg data into rhino 3 0 no problem in rhino 4 0 without using the 3 0 bonus tools.
Of course with a little more work that roof could be a roof from boundary and create a roof system 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.
Grasshopper is launched directly from revit.
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.
As a project matures it becomes necessary to export the rhino models into revit for further refinement and documentation.
Therefore if the rhino file was created in metres make sure the import units are set to metres.
This will activate and import the roof geometry on a layer in rhino called roof.
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.
The sat file will then load into the family.
Check the units in rhino under tools options then either import or insert the dwg plan as a reference.
