An actual size of a 3D reference of
feet and inches, measuring exactly 10 feet/60 inches in height.
This was made in Sketchup, using exact
measurements on Sketchup and converted to CSP as a 3D object.
*The very bottom
line allows it to be grounded for exact measurements in inches and
otherwise aught to be ignored visually.
The 3D object itself only exists in 1
plane, so it will appear flat and may be difficult to see at certain
angles. It also does not have noted inches, but the differing line lengths should make it easier to figure out what you are measuring.
