typical floor MODEL

[Anonymous]

Hi everyone, I want to ask about groups. I know that if you have a building with typical floors a useful way to do it is to create the typical floor, then convert it to a group, and then link or copy the group to reach the high of the building. (this also helps if you change something, because it will change in all floor plans). Is this the best way to do it? Does anyone have any recommendation to work with groups?

* I have to model a building and all floor plan are the same. (Except the roof plan)

What??? You sure you got the right site?

Using Groups is one way.  Another way is create a file for a typical level, link it in the master file and multiply it like mad.

But which one is better? And both let me change something and it will change in every floor plan? I read that I should not connect the walls to a level or a floor, that means when I was modelling the wall do not choose top constraint ?

You can try to check it some explanations. Thanks

I would definitely avoid using groups. For whatever reason Revit doesn't really like groups and the chances are you will get that annoying "inconsistent group" warning a "few" times and other group issues as well.

@Anonymous: Grouping and Linking have advantages as well as disadvantages.  We could advise you much better, if you could share with us more information about the Project itself; not only about the building, but about the team.

Hi, the project is 3 residential building (all the same). It has 12 floors, 1 and 12 are different the rest are the same. The idea is to model just one tower and then copy it two times. Each floor has 4 flats (all the same) and 2 elevators with stairs. The idea is to model first the tower and then the topography. So I'm thinking which is the best way to model the project.

[Sahay_R]

I'm with @Karol_Piroska on this. Groups and overuse of groups are a known contributor to model corruption. It would be advisable to create the typical floor in a separate model, link it in, and as @ToanDN suggests - multiply it like mad. Where there is a bit if a difference - that would mean creating a different model and linking that into the correct location.

In Revit - divide and rule is the definitely the best path to follow. And that is what file linking does.

Hi @Sahay_R

So the best way to model the project is to:

1. Create the floor  2. link the model and then copy (¿or link it again?) until reaching the height of the building   3. copy all again and paste two times to create the others towers.

And if I have differences on the floor I need to create different files and repeat.

Do you suggest to create a file for the tower and then link it to the topography file? or create the tower on the topography file?This is the project, and the tower. If you see they are all the same.

[Sahay_R]

@Anonymous - thank you for the picture! GIves me a better picture of what we are dealing with.

I would start be splitting the tower into Core, Shell. Maybe you would need Fit-Out if interiors are involved.

1) Model the Core. Model the Typical floor in its own model. If there are any non-typical floors, model them as separate models.

2) Link the Core model(s) into the Shell model. Copy the links as needed. Model the Shell around it. You now have one tower

3) In a third project - model the toposurface  and link and copy the final tower model as many times as needed.

Hi @Sahay_R the construction is not with beams and columns is with walls. So when you say core and shell you mean internal walls and external walls? Or what do you mean?

[barthbradley]

@Anonymous: How far along are you on this project anyways? If you haven’t started or completed the initial design yet, you certainly don’t want to deal with Links yet. That’s kind of like putting the cart before the horse. The initial modeling process all about determining geometric interactivity – not how to break up the model into individual working parts of a yet to be determined aggregate.   

My expert two cents worth. 

[Sahay_R]

Yes @Anonymous. I also do see @barthbradley 's concern about you possibly being too far along in the project.

Something that I can suggest - save a copy of the project and archive it JUST IN CASE.

Using the un-archived copy, 

1) Save out a copy, remove everything but the Shell = exterior walls, doors, windows, balconies, etc. This is your Shell model

2) Save out another copy, remove everything but the typical floor. Repeat this process for any atypical floors. This will be the Core

3) If you have furniture and any other Interior Design content - save out another copy, remove everything but the furniture and interior components. This will be the Fit-Out

4) Start a fresh file. 

5) Link in the typical floor, copy the linked file to selected levels. Link in any atypical floors

6) Link in the Fit Out

Hi @Sahay_R

Thank you so much for your time, Do you recommend to do 3 different files for each typical floor and then link it?

[Sahay_R]

No. One file for shell (which is the whole building- you don’t want those ugly lines where walls join up at each story do you?). One for tyical floor. One for fit-out (whole building). Maybe another few for roof, atypical floor. Link all of these together to a whole new file for the whole building. The whole building can then be linked and repeated into a total project file, that has the toposurface in it.

Actually, what I’m saying to the OP is to forget about Linking.  Period. 

[Anonymous]

Hi @Sahay_R
So, I need to create the model file for all typical floors. Then in another file create (link) the whole tower. Finally in other file, link the tower, copy if it's necessary and model the surrounding (with toposurface).
And try to avoid the use of groups.

[barthbradley]

@Anonymous: have you started modeling this project yet?  

[Anonymous]

Hi, @Anonymous
Yes , the surrounding: parking lot, lobby and topography. Now I want to model the tower. I know that I can model each floor and it will take more time, so I want to try it in a more efficient way And I think it would be with link or groups. Because if I need to change something, I need to change in each floor...
