Coordinate entry
In this section we will focus on absolute coordinates, relative coordinates, polar coordinates, relative polar coordinates, and direct distance entry.
One important piece of information is that the origin point is located at the 0,0 coordinate.
Absolute Coordinates - While using this type of entry you must remember that all of the coordinates are based off of the origin point. Think about the game battleship when you are thinking about this type of coordinate entry. Examples 2,5 4,.5 5'6",7'0"

Relative Coordinates - In AutoCAD you will use the @ sign while using the relative coordinates. By using the @ sign you are telling AutoCAD that the point you picked is the temporary "origin" point. Examples @2,2 @4.5,6.25 @5',7'6"
Relative Polar Coordinates - With this type of coordinate you'll need to know two pieces of information:
1) Length of the object that you want to draw, or distance you want to more or copy and object.
2) The angle at which you want it to be drawn or moved/copied.
Scenario: You need to draw a line that is 2 units in length and on a 45 degree angle.
You will begin drawing a line, in this case because we are using a "Relative" coordinate system your first point does not matter. When you get the option to pick a second point you would enter @2<45 This tells AutoCAD that you want a line that is 2 units in length on a 45 degree angle FROM YOUR LAST PICKED POINT because you used the @ sign.
Direct Distance - This type of coordinate system will become the most used. You will drag your cross-hairs in the direction you want to go and simply enter a distance/length.
Dynamic Distance - This style of distance entry the newest style to be introduced to AutoCAD. It is really a more visual combination of the Relative Polar and Direct Distance entry systems. Please take a look at the video below and see it in operation.
