OK, now I gotta ask...

I've been using SU for some time and am reasonably proficient (30%
mark). What is the difference between a component and a group? ISTM
that they're two (different) ways of doing exactly the same thing.
When would I use one over the other?

Hard to beat this definition, so I'll post the link rather than trying
to paraphrase it:

http://www.sketchuptutorials.net/201...us-components/

Basically "Groups" are useful to logically group a single collection of
individual geometry, like assembling six faces into a box, a brick, etc.

A "Component" is appropriate when you want to reuse the exact same
component/collection of individual geometry, multiple times (studs,
beams, stiles, rails, etc.)

Components can also attach themselves automatically to other geometry
(faces, horizontal faces only, etc) and they can also be easily stored
and reused in other files.

The difference can also be an important factor in file size and
performance of the model and computer:

With "groups", each copy of a group added to the model is stored in the
model, thus multiple copies of a "group" add to the file size.

With "components", there is only one of each unique component stored in
the model, all copies of that component inserted in a model are simply
an instance of that one stored component.

NOTE: as stated previously in another thread ... it is well to note that
the use of multiple "nested" components in a model can indeed slow
SketchUp's performance ... regardless of file size.
