importing dwg files in sap2000
when i try to import some autocad file (dwg), i import nothing (blank drawing)...? can someone tell me why, where can be the mistake ?
just dra one line in autocad. save it as dxf. import it is sap using file>import>dxf command. let me knwo if you do not even get in a line. yes after importing, view all and 3d in sap
no, the same thing, i draw 2 lines, in autocad, saved them as dxf file, and then in sap2000 - blank drawing
draw one line only.
change color to red. make sure you do right inputs as commands are promptrd in sap.
actually email me the file
