Best Practice for Groups

[Anonymous]

Hello Everyone,

We are currently building an apartment tower and I thought working with groups would be an excellent idea, as there's a lot of repetition between the levels. The first thing I learned from that experience: Groups in Revit are not as easy as blocks in AutoCAD. Revit complains a lot and I don't always understand why it (randomly?) excludes some elements by example (yesterday it excluded 3 walls including it's wall Opening elements) and leaves others with the same caracteristics inside. As I am not used to work with Groups, I suspect the problem is sitting in front of the computer. 🙄

I would appreciate some tips and tricks, this is what i learned until now:

- Levels and Grids should not be part of any group

- Elements from different Levels should not be grouped together

- Groups inside Groups should be avoided

- Hosted Elements should be grouped with their hosts

- Walls that belong to a group should not be attached to floors

- Groups shouldnt be mirrored

And two questions to my case specifically:

If the walls are identical in all 20 levels and the columns get smaller every 5 levels, should i make one group for walls and another for columns? I suspect it may be bad to join Elements from different Groups (wall from Group 1 and column from Group 2?) 

Should i leave Rooms outside of the Groups?

Appreciate any help here! Cheers!

we are dealing with this issue as well

I set my groups up as a UNIT type (1 Bedroom) (2 Bedroom)(Kitchen) (Bathroom)

they only contain partition walls that apply to that space.

name your groups that make it easy to identify its use.

Rooms should not be part of the group, place them after the group is placed.

confirm the walls in your group are room bounding or not.

the images will display as selected (2 Bedroom walls furniture equipment etc, Bathrooms are 2 different groups and the kitchen is a version of 3 different kitchens.

this allows me to move the groups around more freely if the unit design changes.

mirroring groups is not suggested but it wont hurt too much if the group is in good shape, use discretion when creating your groups and how you plan to use them.

also I have and entry group for Left and Right handed doors to each unit.
