dxf import deletes existing file data

Hey all, first time poster here on the forums. I’m using blender 2.63a and I’m trying to import my 2d cad drawing into an existing .blend file. The import completes successfully, but it deletes all the other stuff that was in my file! Is there any way to get around this?

When importing the dxf file, turn off the “Replace Scene” option.

sometimes with the plethora of options available in blender, it’s easy to miss simple things!! thank you
