Adding to an existing grouped element

Hello All,

Is there a way to add an element to an existing group without ungrouping everything in the existing group and then regrouping with the new element?

No.

Ungroup/group is pretty quick using keyboard shortcuts.

You can have nested groups, but it is generally not recommended, since it can affect performance according to GS.

HTH,

As James says, keyboard shortcuts make it easy ..

Select GROUP and NEW ITEM
CTRL-SHIFT-G
CTRL-G

... of course, wouldn't it be nice to have a button (or macro facility) to allow 'ctrl-shift-alt-G' to do the same

What are the issues with nested groups? I use them all the time without incident (that I know of).

Take a look at ArchiGuide; quite an extensive article on the nested group and their possible influence on the speed.

We use 'nested groups' extensively but systematically, ie. low-height modular partitions are grouped with worksurfaces to form a workstation. This is grouped with a chair (which is on a different layer). Four (or whatever) such groups are then regrouped to form an 'X'. And so on.

Facade modular elements (window frame surrounds, etc.) are also similarly hierarchically grouped.

Even on our largest projects we have noticed zero speedup on a trial when everything was ungrouped - so I figure SENSIBLE hierarchical grouping does not materially affect the AC engine.

Of course I could imagine that 'careless' use of the group tool could lead to delays. The speed of the computer probably relates to how noticeable this is to the user.

I would recommend 'in house' testing to see what works for you.
