Polar coordinate entry

“

- The third entry system we can use in AutoCAD is called polar coordinate entry. Like relative entry it's one that we're going to use a lot. Polar coordinates are entered in a magnitude direction format. This means we enter the values as the length of the line that we wish to draw or the distance we wish to move our object and then the angle we want that distance to travel along. Again we're going to go back to grade school geometry here and recall a 360 degree circle. Angles in AutoCAD are calculated using this 360 degree circle. Angle zero here is always exactly right horizontally and is considered our origin point here, just like the Cartesian plane. As we work our way around we find that 90 degrees is straight up and down vertically and continuing around counter clockwise we get 180 degrees, which is horizontal. Straight down is 270 degrees and back around to our starting point of zero degrees which is simultaneously 360 degrees. This means that an angle of 45 degrees would be…
