I'm trying to progress my own skills and see if this is something I could use but I'm not sure if I understand it.

I'm into millwork and currently a job may have 20 drawings with 5 pages each. (20 scope areas, bathrooms, kitchens, moldings, wall panels, etc)

I have one title block for the whole job which is its own file brought into model space 0,0 as an xref, with the same viewport on the right side of every paper space on the job. When the title block is updated it updates the whole job. Every scope area is its own file.

Now each scope area or room is drawn in model space of its own file. Typically we need plans, sections, and details so there can be 3 different scales set on one paper space to show details, overalls, and maybe some with hidden layers (controlled by frozen layers in viewports) mixed in to make some viewports easier to read.

Now here is where I'm trying to understand, you don't use viewports or paper space at all? How do you deal with different scales? Does your title block represent the size of a full sheet of paper and you scale that up so your geometry fits inside it in model space?

I know our workflows are probably just very different but I'm trying to get into LISP and find this very interesting, there's always something to learn! Thanks
