what is dimensioning
Adding measurements to a sketch
Adding lines to a sketch
adding extra lines for the image to make sense.
adding a 2d picture to your sketch
what is the rule of dimensioning
No extension lines will cross, no measurements inside the drawing, no measurements of hidden lines, no connected extension lines.
measure the length of an object, add measurements for hidden lines
don't add measurements, only add lines
add an arrow to show how long your object is.

use hash marks to help find the accurate measurement.
use the rule as a way to make a strait line
use lines and estimate on the measurement
