I have been given the task of creating a Revit BIM model from existing previously as-builts for a remodel project. The caveat, is the as-builts are not complete and mostly hand drawn. There are some hand drawn floor plans, a few details, exterior elevations, and a few CAD floorplans as well, but it is missing wall sections, RCP, door schedules, interior elevations, etc.
I'm hitting a wall as to how to address modeling the Revit in 3D when I don't have a complete set of 2D drawing information to go off of. Did anyone else stumble upon a similar issue? For example should I model generic 3D doors so that can atleast show up in plan and revise them as appropriate later in the design stage?
The other option is I could go measure in the field, but that wouldn't that require so much tedious and potentially inaccurate work?
Opinions and insight appreciated! Thank you.

If you have floor plans I would draw as much as you can with what you have. Put your doors in where they are on the plans and if needed as you said revise them as appropriate when you get the correct information. It really depends on what you need this building in Revit for and how much time you are willing to spend getting it correct. Since you don't have a complete set its really not going to be accurate anyway you do it but I would take this approach and just draw as much as you can with the information you have.
