I am working on a model of a .223 Caliber bullet, when I use 1 povunit =
1 inch I get a weird 'squatty' bullet. If I scale by <1,2,1> it looks
'right' why would I not get a correctly porpotioned image without
scaling it? the image source below will generate 2 objects, left is
using actual measurements the right is scaled.
