When I upload single .dwg file if I click on the web-page right after comes up an error message (see Error.jpg), if Iwait a minute then just nothing happens.
I tried uploading .dwg files generated in AutoCAD Civil 3D and the same one saved as 2004 version.
2004 version has AC1032 in the begining and Civil 3d has AC1018.
But I'm more interested in Batch Upload. Do I understand it correctly, that with Batch Upload it is possible to upload dimensions, device coordinates, wall coordinates and building material?
