Problem with importing DXF to Etabs?

[drile007]

Few months ago I've import DXF file to Etabs with no problem. Walls and floors were Polyline entities. Now I made DXF file where walls and floors are Lwpolyline entities. Importing doesn't work. I tried with command PLINETYPE in Autocad to "convert" Lwpolyline to Polyline but it didn't help. Can you help me out?

Thank you in advance

For floors use a polyline, but make sure it is a closed polyline.
For walls, import them as beams (draw them as lines). Trace the walls in plan on the beamlines.
