I can’t take full credit for this post, as it was Becks Aaron Maller who reminded me of this, as it seems that I had wiped it from my memory. Neither the less, let me explain. More often than not, project teams working on residential schemes will use groups for apartment or flat layouts. If you apply a sound strategy, with clean interfaces between the elements in the group & the main structure of the building; this actually works well.
I also recommend to users that they don’t mirror the groups, instead they create left & right versions. In this instance, if I did require a handed version, I would group, name appropriately, mirror, then ungroup the mirrored version, regroup & rename as the handed version.
So you can then happily use your groups in your project as long as you are mindful of the limitations of groups. But what about scheduling? As it stands, in Revit 2013 we can’t schedule groups. So how do we get around this limitation, especially where you might have to schedule apartments or flat types in a project; a common practise in residential projects. The answer is to create a very simple generic model family which includes the mark parameter & ensure this is included as part of your apartment model group. It doesn’t have to be anything too spectacular, it can be as simple as a few symbolic lines which can be controlled & categorised with subcategories so it can be easily found, located & displayed. When the groups are placed in the project, you can use a multi category schedule & pick up the mark parameter from the generic model family. This is a great way to push data back into until group as well, by driving data from the schedule into the generic model family within the group.
In Revit 2014 we still can’t schedule groups! However some minor enhancements open up more opportunities to push data into elements within groups & allow us to schedule this data. The reason for this, is we can use the “new variance parameter by group” functionality in 2014. Let me explain how this could be used.
This example gives a brief description of the implementation process. Typically I would probably use a generic model family as well as shared parameters as my data collector in the group, but to demonstrate the process I will create simple in-place generic model family. Copied from David Light.
