Error while importing dxf to section wizard in Staad Pro from AutoCAD

Question

I am analysing an RCC box girder for which some peculiar tapered sections have to be created. I created a tapered rectangular section in AutoCAD 2014. I used polyline to create the 2D and then extruded it to make it a solid 3D section. Now when I import this into section wizard, I get an error, "Import error". I tried saving the AutoCAD file in various formats of .dwg and .dxf but the same result. What is it that I am not doing right?

Please save the .dxf in auto cad 2000 version and then try to import it. Hope this will solve your issue.

Can you please send me the .dxf file also please tell me the version of STAAD.Pro you are using.

Abhisek M · Answer

you can upload here.

Your file contains multiple drawings of the same section in the same location. Also, the dimensions are also very less. Can you please create a new dwg file with appropriate dimensions in mm and then try to import that? You need not make them using polyline. Normal line is enough.

Even if you draw in meter I think there is no option to import with that unit. When you import that .dxf it provides option to choose unit. Choose appropriate as per your need. For creating rendered view you need to provide profile points.
