    Speaking of multilple models...

    I have my first multiple building project to be done in Revit coming up. In the back of my head my initial plan was to have all of the buildings in one model but I also know that I can have multiple models and link them together.

    what are the plus and minus factors for each direction? Are there any things related to project size or type that would make a difference? This project has two 2 story and two 1 story buildings so it's a rather small job. And, of course, I'm just doing the glazed window and door openings.
    I'm retired, if you don't like it, go around!

    I think linking files has more sense in a teamwork environment. Since you work alone, having other buildings in separate files is not going to help you much if nobody is going to be working on other parts of the project while you work on one of the parts. On the other hand, it can bring you more things to take care of, that you don't have to deal with now, such as handling visibility graphics from linked files, multiple level symbols, scheduling things from linked files, etc.

      Are the floor to floor height the same on all buildings ? If not, definitely go for linking each building into a master file, otherwise the different levels will by a nightmare while modeling.

      I work alone too, and often use linked files (multiple buildings, site, repeating units, etc.), so it´s not only great for teamwork. Though it does take some time to fully understand the issues with VG, tagging, scheduling, etc. as Alfredo pointed out :beer:

        Pros linking:
        - Reduced file size on seperate projects
        - Less trouble with creating separate schedules and quantities for seperate buildings
        - Less coordination problems between buildings. Like Munkholm said, if there are different floor heights or small design differences between buildings working in a single project can be a nightmare, especially with curtain walls!

        Cons linking:
        - Takes some time in setting up (like already being said: VG, tags, schedules if needed, etc)

        I also work alone and use linked files a lot. Especially when there are different buildings in the project.

          Do you guys have issues with rooms while working with linked files? Say for example that I have 4 apartments, which are part of a typical floor plan. Suppose that each apartment was done in its own file, then in another file, I put them together to make a typical floor plan, which I want to repeat for floors 2nd to 8th of a building . Therefore I select all the floor plan and make it a group. Then I copy and paste this group to the other levels to make the tower. My question is, in this work flow, when and where is the correct time and place to create rooms? In this project, I created rooms in the original small file of each apartment unit, but then when I put everything together, and create the tower, I get several errors related to rooms. Do you guys have any recommendations about this?

            What aer the specific errors you are getting? I find that creating the rooms in the apartment unit files which are then linked in, has always worked very well. The other benefit ti this approach is you can then also use rooms in the main model to denote the area of the apartment, rather than using area plans which are less intelligent.(ie, don't find the boundaries of individual units automatically).

              I have had some issues with linked files in the past so I always do this in the model that contains the whole building. (meaning that in the case of the OP I would do it in the various files that each contain a building and not in the host file, and in your case I would do it in the host file.
              I don't do rooms in groups, I normally just select all rooms using the filter tool and then copy them to the other floors using copy/paste.

                We use Links all the time, and they work great. 2 Buildings? 2 Models.

                  I guess the problem I am having is because I am including the rooms in the groups. I am going to try what you say about just copyng and pasting the rooms apart from the groups.

                    I probably should have elaborated: I meant using Rooms in relation to Linking. I always place the rooms in the "whole building file". So if it were a project with 2 buildings in two files, I will use the Child-project to place rooms (how do you call these btw?)

                    When parts of a building linked in to create the total, I will use the Parent-project to place rooms.

                    I think so yes. Don't get me wrong: it can be done, but it's easily screwed up. I believe that you can group them, as long as the group contains all vertical borders (aka walls) to all rooms. So if you have an appartment dividing wall that isn't in the group, you (or at least I) tend to run into problems.
