Hi Igor - also I'm attaching here the saved .rvt file from Revit after inserting each of those SAT files (the ones that I previously posted in the spheretest.zip attachment).

After loading the file into Revit, you should see this type of display initially:



Then if you select the objects, you will get the enhanced display that seems to go with selection, with some more edges displayed:



Also if you switch the View properties to turn shading + edges on, it looks like this:




Do you get different results than this?
