This can be done with AutoCAD MEP 2015, or Architecture, or similar verticals that have the IFCEXPORT command.
- Open AutoCAD MEP
- New DWG file
- IMPORT -> select SAT file
- Open IFC in Revit
The advantage of doing this over importing the SAT directly to a Generic Model family is that the IFC method will result in individual forms for each bit of the SAT file. If there are 1200 forms, you will get 1200 families in Revit. This, in turn, will export to Navisworks with this level of element hierarchy (instead of just one big imported SAT element).
This will also result in higher granularity of clashes when using the converted SAT via IFC method (more forms to clash against).
You probably know that you can attempt to explode a SAT in a Revit family, but I find that sometimes unsupported elements disappear using this method… so I like my way via AutoCAD a bit better at this stage.
