Polar coordinate entry

“

- [Instructor] The third entry system that we can use in AutoCAD is called polar coordinate entry. Like relative entry, it's one that we're going to be using quite a bit. Polar coordinates are entered in a magnitude direction format. This means that we enter the values as the length of the line that we wish to draw and then the angle that we want that line to travel along. Again, we're going to go back to grade school geometry here and we're going to recall a 360 degree circle. Angles in AutoCAD are calculated using this 360 degree circle. Starting from the origin point, we have angle zero, which is always to the right horizontally. And then, working our way around, we have 90 degrees, which is straight up, 180 degrees, to the left, 270 degrees, which is straight down, and then 360 degrees, which is also simultaneously zero degrees. This means that an angle of 45 degrees from the origin would be somewhere in this…
