Phasing or multiple files for renovation concepts

[ttocsvtec]

Hi guys,

I'm relatively new to Revit, (but have an extensive AutoCAD background) and Im having some trouble coming up with the best way to give a client multiple options for a renovation to an existing space. My question is would it be better for me to create one file that has an existing, demo, new construction opt 1 phase and a new construction opti 2 phase or would I be better off creating a 2 copies of the file and rename them option 1 & option 2 for the two scenarios? Any drawbacks or advantages to either one would be appreciated. 

TIA

Revit even has a separate function for these instances Design Options.

I normally look at the project (complexity, size etc) and estimate my clients wishes. For example if I expect that the two (or more) design options wil run parallel and/or are diverting for quite some time I might opt for two (or more) separate files. If iI expect only (many) minor differences I might choose design options.

Phasing I normally do not use for these kind of things. Phases are more sequential processes. Design options are (usually) notsequential and might cause conflicts when used for degn options.
