Using sat files

Received an enormous sat file from the steel fabricators today 225mb. Decided to link it into our Revit model - slow to load in and made the model unworkable. The answer was not to link to the sat file, but to import the sat file into a clean Revit project, save that and then link that Revit project into our model. The size of the project with the sat file imported into it was 30mb - a massive reduction.
