I'm a Revit expert and specialist and I'd use it to do this job.
With this tool, in fact, it would be easy to perform an accurate check of the various sources: existing DWGs, surveys, photos, images, PDFs, hand sketches and so on, correcting errors and ensure drawings consistency.
A Revit model is a complete design of a building including openings like doors and windows, furniture if needed, and all other architectural (or even structural) component.
Once a Revit model is built it would be easy to extract all the needed views in AutoCAD 2011 file format and, above all, it can be used for further designs. It is a 3D model and can be rendered within Revit with good results but note that I'm not able to produce photorealistic images!
