I've using revit architecture suite 2010. And i want to convert a 2D drawing that use autocad into revit architecture.

So, in revit architecture i try to import using "import CAD" button. And before that, i already explode the CAD file and turn it into proxygraphics = 1.
I also change the import units as millimeter & change the positioning as Manual-Center, in Import Cad Formats.

But unfortunately, when i already import it gaves me a message,

"Some elements were lost during import. ActiveX and some proprietary components cannot be imported"

and

"Some numerical data within the imported file was out of range. This numerical data has been truncated."

And after that,it doesn't import any drawing at all in revit.

Any idea how can i import the CAD file into Revit Architecture?
