I am using RAM CONCEPT 5.0.1 to generate the mesh of the plan, to use it in ETABS 9.7.4 I couldn't find a direct exporting option ...
So how can that be done ?
You'll need to use AutoCAD (either dxf or dwg) as a go between. Both can import from/export to AutoCAD but otherwise don't talk to each other because they're made by different companies.
