Type x,y coordinate when AutoCAD asks for a point. The positive Y values are above the intersection and increase up. The positive X values are to the right of the intersection of the two axis. The X axis segments increase in value to the right. Each of these axis is further divided into segments. These two axis intersect at the bottom left corner of the screen. The Y axis runs vertically along the left side of the screen. The X axis runs horizontal across the bottom of the screen. The Cartesian coordinate system divides a two dimensional plane with two perpendicular axis. Any entities place on the working two dimensional plane can be defined relative to the Cartesian coordinate system. Click Yes to save changes or No to discard changes Cartesian Coordinate System AutoCAD provides the user with an infinite two dimensional area to work with. Type a new drawing name or keep the existing drawing name. Type SAVE or SAVEAS at the command prompt. AutoCAD saves its drawings as files with extensions ending in.dwg. The first time an unnamed drawing is saved the Save As dialog box appears. Command: NEW Saving Drawings Saves the most recent changes to a drawing.
