Hello,
In our Company we are usin TEKLA for Steel structures...

I have got the ifc. export file from our customer. It is some Garage, with concrete deck on the top.
As you can see on the Picture 1 the in ifc Viewer is visible, but after the importing into Tekla it is gone.

Gegenerell it can be, because this deck is exported as one Piece, but in different Levels.
And so Tekla can`t recognize such a constuction. This is a deck 32mm, which haas to me in different Levels because of rain Water. This is all perfect, but I Need to have geometry in my program.

As I`am not an expert in Nemetschek, I`am asking you if we can advise him something ho to export this parts as a simple decks. Is it possible in Allplan?

I don`t understand this, becasue this Ifc is Visible in Tekla Bim-Sight.
