How to convert from 2D to 3D -Question

I am a novice in Solidworks.

When I was trying to convert 2D( *.dwg from AutoCAD) to Solidworks. An Error message was displayed on the screen.

The message is that "2D file size is too large to convert 3D (Solidworks)".

How can I resolve this problem?

Can I get any help?
