AutoCAD Group Command

When we use the GROUP command to temporary copy a set of entities I can easily copy the entities; but then when we try to explode the group (from the group menu) only the original is explodes. Can we"explode" the copies?

I understand that the recommended approach is creating a block, even if it is just a BLOCK and not a WBLOCK; but according to websites I have found (below) one of the biggest uses is to copy a set of entities from one area to another. However, you will have issues if you want to make a change to anyone of those copies...ever.

I am also wondering if what other uses the GROUP command can provide that the BLOCK command cannot? Is the GROUP command a legacy command and not maintained by Autodesk any more?

Thanks.

GROUP is for temporary gathering of entities together to move/copy and edit
as one. You can toggle grouping off and on with CTRL+SHIFT+A. Perhaps the
latter is all you need to do?

BLOCK is for a permanent 'grouping' of objects. No turning off or on, but
you can edit one block, once, and all other instances change to match your
edit. They are also easier to search and track using QSELECT and FILTER
commands.

There is no object type called WBLOCK: that's just a command to make a block
inside a drawing into an external DWG file, otherwise known as a drawing
file.

Neither one replaces the other, and neither has replaced the other. Both are
still around and are core functions.

Knowing when to use one and not the other comes from experience, and
mistakes, and needs like the one you just expressed.
GROUP command assigns a unique name to each group, and each copy will also
have a unique name: you should be able to track them on the pop-up if you
check the unnamed boxes (or try List command). You should be able to ungroup
(explode) by selecting each.

1) Can we "explode" the copies.
Yes. In the group command, press the "find name" button. Then select
an item in the group. If there is an asterisk as the first character, the
group is unnamed. This means that you need to check the box in the group
command that says "include unnamed". Pick the group you want to explode and
then pick the explode button in the change group.

2) Is group a legacy command?
The group command has remained relatively unchanged since its inception.

3)What is the recommended method(blocks, wblocks, or groups)?
Whatever floats your boat. Groups have both advantages and disadvantages
over blocks. I use both. Too many groups create management problems so I
use them sparingly.
