need you help. To use autocad model in SAP2000 software or ANSYS I use .dxf file and choose autocad 2004/LT2004 or 2000 to import it to SAP2000 v14. But it don't work given that the .dxf file generated by Autocad2006 work perfectly.
please help in my computer I have only Autocad 2012.
I have Autocad civil 3D as 2012 software in Window 7 OS.
I downloded "autocad_plant_3d_2012_object_enabler_english_32bi
But it do not seem working.
Sorry it in french but it say that you have to download an enabler.
Forget enablers, because you have only to export 3D geometry (not Civil features) to FEM software like Sap or Ansys.
I feel it will be very hard to shoot your trouble, mademoiselle.
The point is to find a DXF2004 format compatible with your FEM, starting from Autocad 2012.
One possible solution is this one: try and let us know about it.
