This is an old issue, but hoping for new answers. I save my model to SAT format. When I import to REVIT, i get an error that some numerical data was out of range and was truncated. Then the model is imported, but another message says some ACIS data could not be imported. the resulting model is then inserted to REVIT, but I am unable to position it.
Have many such errors about ACIS data that could not be imported.
I do use SAT 7 but still have the same problem. I have also tried IFC with the same result. I have read a thread on the REVIT forum that said they were working on the issue. That was in REVIT 2017. I have 2018 and still no fix.
