No, those are primitive 3DSMAX boxes of different sizes, jus made to illustrate my point.

But I made a much more conplex geometry in AutoCAD (then imported in 3DS), and was looking for a way not to make different instances of objects meant to receive the same texture.

But it looks like this scaling problem will force me to get (is i a freebie?) and learn UV Mapper.

Thanks to you all for your useful answers.
