Hi Danny, 
 
> I understand if you model something tiny weeny 
 
But what "tiny weeny" means to the program is if the numeric value are small, like if you are using numbers like radius = 0.0000000001  or things like that. 
 
For example if you have units = Miles, and then have a sphere with radius = 0.00001 miles, that is a nice reasonable size in cm, however it will still be seen from the software's view as being tiny weeny because the numbers being used are tiny.
