Revit Structure is slightly different to the other programs because there are two ways to link it to SPACE GASS. In addition to being able to communicate with SPACE GASS via the CIMSteel/2 and IFC Step file links, Revit Structure can be configured to create SPACE GASS jobs directly and also update the Revit model from them.
The advantage of using the direct Revit Structure link over the CIMSteel/2 and IFC links is that after you have transferred the model to SPACE GASS, you can import the section property and steel design changes back into Revit Structure without completely replacing the Revit Structure model.
The advantage of the CIMSteel/2 and IFC Step file links is that you can start with a SPACE GASS model and transfer it into Revit Structure to create a Revit model from scratch. You can’t do this with the direct Revit Structure link.
Of course, you can use a combination of methods. You could start with a SPACE GASS model, export it using CIMSteel/2 or IFC to create a new Revit Structure model, add to the model in Revit Structure and then export it back to SPACE GASS using the direct Revit Structure link.
