Carrara used to have no unit component to it at all.  It was a unitless program.  Then around version 4 or 5 (or so), the code all of a sudden introduced feet and inches and everything that I made in earlier versions got all screwed up.

This issue continues to get worse as the code has evolved this concept of scene size.  I don't fully comprehend the value of having the option of scene size.  I don't think it has any value at all in terms of the way it's been utilized in the code.

It seems to me that it would have been a lot easier to just reset the grid in the assembly room to different settings to manage assembling "big" things/scenes or "little" things/scenes.  As it is now, It's just kind of messed up.

I don't know if this particular feature was done in order to manage the importation of models from other packages or not (I have no idea).  A few more user options to manage this situation would have been nicer.

As it is now, I think it would be nice to have a global rescaling tool.  When I pull up my old models, sometimes I have to rescale them by several 1000 percent to get them to scale with other newer parts (it's stupid).  I would like to rescale a model permanently without having to live with screwy huge scaling properties all the time with old parts.

So, I don't know if there are bugs in the code but I do know that the code works in a funky way now.
