To get around your problem, maybe this will help: 1 unit is (about) 10
inches.

The fun everyone is having. GEESH!
I just put my monitor on the floor facing up and sit really, really
close. Z is up and working in miniture is easy.

Actually, wouldn't you need to hang it from the ceiling to be accurate??

That could lead to some interesting headlines: Man killed after monitor

Your geometry teacher supported the idea that the Y axis is altitude in a 3-axis
system? No wonder the American education system is going to Hell...<G>
I'm not happy with 1 unit=25 meters, either. I usually use a 1 unit = 1 meter or
1 unit = 1 foot scale (depending on what I'm creating); our entire house would
fit into 1/5 of a unit square at his scale. I'm not used to drawing things so
small. That's a lot of detail to cram into a small space, I'm thinking.
jbm!

I agree with you 100%! : )
It really should be 1 unit = 1 meter or whatever, even if you do have 5 or 6 digit
numbers after the city starts to get put together, it will make the dimesions seem
more realistic. This should be fixed asap before this city gets set up too much.
Also, the city uses an ordinary flat plane for the ground. This could be a problem
if you want a basement. I think it would be better if you had to have a green cube
underneath your house and you could difference it as needed. Plus, it adds the
creativity options of being able to set up a desert palace or a volcano fortress by
changing the color and texture of the ground. Hmm...

Yah, I'm an american too and the metric stuff always gets me. so what
i did was make a few defines, as follows:
// in case i want to conform with the world...
#declare jgbMeter = 1/25
#declare jgbCentimeter = jgbMeter * 0.01
#declare jgbMillimeter = jgbMeter * 0.001
// in case i don't... :)
#declare jgbFoot = jgbMeter / 3.281
#declare jgbYard = jgbFoot * 3
#declare jgbInch = jgbFoot / 12
(my initials are jgb, so i append all my variables for my plot with them
so that I can avoid conflicts with someone elses variables). Then,
whenever I specify sizes & translations & positions, I just say, for
examples, "5*jgbFoot" and voila! i get five feet in the scale
specified. and i can even mix metric and imperial since the definition
of jgbFoot is based on the definition of jgbMeter.
Anyway. Just a suggestion i thought might help some people, since it
has saved my hide many times!
- ciao!

There is no "correct" way - just go with the rules specified, as you
say, all it does is give you a tiny bit of hassle at the end before you
post your efforts.

Surely you realise that scaling is just arbitary - if you are using 1
metre not 25, then the whole scene (probably unioned) simply requires a
"scale 1/25".
Mind you, thats all a bit daft now, as the scale has been changed to 1
unit = 1 metre anyway.

That's what I meant.

You should check the date on the message you reply to before wording a sentence
that way.

Well, it MIGHT--but that don't make it right. Most navigational systems use
X/Y for surface coordinates and Z for altitudes. Maybe I'm just being too,
um, retentive here, but it bothers me.
jbm!
