Autocad file from architect to X6

[prphotos]

Hi everyone. Fairly new to chief architect. I have an Autocad file from my architect that I would like to import to x6. They sent it with many layers and non of the real predefined layers that chief manuals talk about (walls, windows, doors). Not sure the best method to import the plan. When I try to import there are 20 layers all labeled different sections. When I try the cad to walls it looked a mess. Any ideas?? I cannot get the files again, the plans are 5 years old. Also wondering what you would do if you bought plans from a site like eplans, and wanted to import?? Any help would be great.
