After you toggle off Auto Join, the lines you draw beginning at an existing end point are not joined to existing lines. On the context menu, clear the checkmark next to the Auto Join Lines option. To turn off Auto Join, context-click while the Line tool is active. If you toggle off Auto Join feature, the existing line or lines and the newer line or lines won't share a context when you select one of the lines. The Auto Join setting controls this behavior. As a result, after you finish drawing and select one of the lines, both the existing and new lines share a context. When you set a line's start point at the end of an existing line, by default, the new line joins the existing lines. Click to place the line's end point, and the tangent line appears. The line also seems to snap to the tangent point. After you place the start point, move the cursor until you see a rubber band-like inference line running tangent to the current mouse position. You can also set a line's start point on a circle or arc. Then click to place the end point at the tangent point. If you need to draw a line that is tangent to an existing arc or circle, you can set a start point anywhere outside the circle and then hover the Line tool cursor over the edge of the circle until the the Tangent point inference appears, as shown in the following figure. The second value is the number of default units from the line’s starting point. The first value is an angle, measured counter-clockwise from the positive X axis. Values are relative to the line’s starting point. The second value is the Y, or green, axis. Values are measured from the upper left of the drawing area. After you type the end point coordinates, press Enter or Return, and your line appears precisely as you indicated.In the following figure, the end point was created with the absolute coordinates. After you define the first coordinate, you can define the second coordinate, or end point, with one of three coordinate types: absolute, relative, or polar.For example, to set the starting point shown in the following figure, type an absolute coordinate of and press Enter (Microsoft Windows) or Return (Mac OS X). Absolute coordinates are measured from the upper-left corner of the drawing area.
Click in the drawing area or type an absolute coordinate value to set the starting point.When you select the Line tool, the Measurement’s box is ready for you to type precise points, or coordinates, to define your line.
