My explanation was ambiguous at best ;-) As the total object is a merge 
of tuit + text, there is also only /one/ mm_per_unit value.

What I am struggling with is the /meaning/ of mm_per_unit. I am 
understanding the sense of it but am unsure how to interpret it in a 
scene. I need to ponder Alain's answer above a little longer, if my 
brain accepts to fire up...

...so it doesn't matter what the /size/ of the object is as long as you 
fix for yourself what a pov unit corresponds to in the scene. OK, fair 
enough. In most of my scenes I have a clear idea about this. However, in 
a test scene like this I just meddle around without clear notion about 
true sizes. With sslt I should thus start with determining that beforehand.

Thanks! Much cleared now. I supposedly did not read the docs well enough 
in the first place it seems.
