for something with a lot of the same objects i'd think it would ease the process of laying out the UVs if you did it early so then you only have to go through unfolding it once. you can leave the arrangement of the UVs until you're done modelling.
at least, that's how i'd do it.
although i suppose there's suppose to be some way of transferring uvs of one object to another easily, but i think it'd be faster to just do it once and not mess around with extra functions
that's a "Ch" pronounced as a "K"
Computer skills I should have:
Objective C, C#, Java, MEL. Python, C++, XML, JavaScript, XSLT, HTML, SQL, CSS, FXScript, Clips, SOAR, ActionScript, OpenGL, DirectX
Maya, XSI, Photoshop, AfterEffects, Motion, Illustrator, Flash, Swift3D
