Im starting to have the same problem as I was having when Archicad 19 first came out where you are unable to Relink a 3d elements home story
but this time it is via the Cross Section window in AC18
im sure I am able to do this in 20 so why not in 18?
Also the same thing im unable to group 3d elements in the Cross Section window only in 3d or in floor plan.
why is there such reduced functionality in the cross section window it should be the same everywhere!? this is a fundamental programming design flaw.
