Why waste your time manually converting DWG files to Revit lines when this macro can do it for you?
DWG to RVT PRO automatically converts imported or linked DWG files to Revit lines.
The macro converts DWG files to detail and model lines as well as area boundaries, room separation lines and space separation lines. Specify a different Revit line style for each layer in the DWG file or skip certain layers you don't want in your model file.
The download includes two RVT files (version 2015 and 2016) as well as instructions in PDF format.
