Common ways to enter coordinates in CAD are to enter X, Y coordinate values in 2D drawings, and X, Y, Z coordinate values in 3D drawings. Apart from these, the CAD system also provides polar coordinates, cylindrical coordinates, spherical coordinates. When entering those coordinates, we can either enter absolute coordinate values relative to the origin of the coordinates or enter values relative to the endpoint.
Absolute coordinates: is the distance or angle of the axes relative to the origin of the coordinates.
When entering absolute coordinates, enter the coordinates of the points in the command bar. For example, to enter absolute coordinates we need to draw a line from point (-3,2) to point (4,4), first, enter the line command and then enter as the following shows :
