When moving a vector using the Move Selected Objects tool, what is the difference between Absolute and Relative modes?

Absolute mode will move a vector or component using the drawing coordinates.

For example, you have a circle with its center at X = 3, Y = 7.5 and you want to move it to X = 6, Y = 4. Select the circle and press M, the shortcut key for the Move Selected Objects tool, then select Absolute and the center anchor point. Change the value in the X input box to 6, the value in the Y input box to 4 and select Apply to perform the move.

Relative mode will move a vector or component from its current position by the number of units entered in the X and Y input boxes.

Using the above example, you would select Relative and enter +3 in the X input box, -3.5 in the Y input box, then select Apply to perform the move.

Note: An anchor point is not required in Relative mode as the entire shape will move the same number of units in X and Y based on its original position.
