Hi @karenrunthal ,
Your initial post was:
"I can only see 2D floor plan from a different angle, even when switching to 3D. No walls, roof, etc. Swg file is saved in Archicad 26 as firstfloor.swg and secondfloor.swg. "
But it was removed for some reason.
If you can see only 2D drawing exported from Archicad, then, apparently, you used the export from Archicad incorrectly.
In Archicad you need to open the 3D window of the plan and then save as DWG. This will export 3D data to DWG format.
