In Revit I use many linked rvt file, where almost all are put on overlay.

So in Revit I don’t see the links in the links.
When I render this Revit view in Enscpae I do see the links in the links, with lots of double geometry as consequence.
Someone has the same issue, or solution.
Changing everything in Visibility graphic and set on custom is to much work.
