When you model do you only build half?

[Tekkybot]

i ask because i find my brain has a really hard time thinking in halves.

:edit: man, i need to read my sketchup7 for dummies book more often i completely forget about making the box into a component

I make components out of anything that'll be repeated. And I group every major 'object'. But I rarely have symmetrical objects.

If I'm making a model to be used in SU only or shared then I am weary about sizes and model using symmetry and groups, if I intend to export it to another app for compiling and render then I model as I please with no regard for size as no matter how I model in SU, most if not all 3rd party apps do not recognise SU groups or components so why waste time being conservative.
