OK I was drawing a part in AutoCAD and drew it to full size
the full size part fits on an a 17.208" diameter airframe
the scale airframe I am using is a 6.148" diameter airframe
so to get the scale factor I divide 6.148" by 17.208" and get a result of .3572
the full size part has a front to back measurement of 4" and when I scale it to .3572 I get a front to back measurement of 1.4'
sooo I assume if I multiply the scale front to back measurement of 1.4 by .3572 I should get the original full size measurement of 4" ??
then why am I getting 0.50008" ?
.3572 x 1.4 = 0.50008 should the result be the original size of 4" ??
