What is the best method to model multistory buildings with reapeating plan layouts?

[Caed9]

So for Multistory Buildings and Typical Layout plans, the only quick editable way of doing it, is by grouping the Typical plan and then copy the group and paste aligned to selected levels?

I just want to check if there is a different way of doing it cause groups are kind of problematic sometimes. Its my first time attempting this kind of models. 

I appreciate your opinions and feedback, thanks in advance.

I guess groups are supposed to shine in this circumstances. Cause I ain't gonna link Revit files. 

I did the research, Though the first time did not lead me to this post, I found it while doing the research again.

What exactly do you mean by Groups are problematic? I follow the same process as you mentioned in your first sentence. Maybe a little more detail on the issue with Groups could make it easy to think of a solution.

Are you just talking about using groups as a way of copy/pasting to levels?  Groups wouldn't be a problem. You can always ungroup after copying and pasting to levels.

I notice when I work with groups Revit gives more error messages, For example you can't constraint families inside a group to a Grid outside the group. I may relay on Ref planes inside the Group though.

I also want keep them editable in case a change has to be done. Cause In that Case I'll have to delete all and copy and paste again.  I guess Groups are the best way.

Like I said, you can always ungroup 'em.  But sure, keeping 'em in Groups is great - until it's not.  😉

I see, Ok I'll just ungroup once I make sure all changes are done, Thanks for the advice I'll keep that in mind!

Why do you need to ungroup? 

Just edit Group to make changes, add new elements, remove existing elements.

I do a lot of townhomes in Revit - At first I started using groups I stopped using them because tags notes dimensions will not copy from group to group and I was getting a lot of errors. So What I do now is to create the "internal" unit or better yet, the portion of the unit that repeats and does not change. I then reference this file into a master set where I create the "shell" with exterior walls, windows etc. this works best for me.

Attached detail group to multiple instances of a model group.

Please explain

Once you have an attached detail group, you can add it to any/all instances of the parent model group with a click of a button.

If by townhouses you mean Rowhouses. I think  you may also consider linking Revit files instead as in that case you are dealing with a site that contains a repeating pattern of rowbuildings (Horizontal), not stacked repeating floors (Vertical). The site is more prominent in those kinds of projects, because of the topography, the property shape, etc. But Grouping and creating the attached detail groups sounds like a nice way to avoid linking revit files.

Two words that mean the same. I'm sure they meant townhouses.

[barthbradley]

Attached Dwellings.   

Let the developers decide what to call them.

I assume you are doing core n shell, not multifamily ?

The answers depend on scope of deliverables and how do you want to address building issues to AHJ and coordinate w consultants and present it to client.

Seeing from those perspectives will give you a clear sight (or oversight) how to model the building.

Does not work, annotations dont get added or grouped....thats why I link the interior units to a master set that has the shell

[Caed9]

well I’m modelling all, structure, architecture, and plumbing on the same file. no furniture though.  And those groups are headache, the grouping part is just for easy selection basically, cause the editable part lacks. Cause those groups are problematic.
