Perspective line tool
With the Perspective line tool, you can drag and constrain a line to recede toward the nearest vanishing point. You can easily create shapes that appear as vertical or horizontal planes in space. Click and drag to position a line, then release the mouse button to create the line. To continue a path, simply click on the endpoint and drag. Hold down the Shift key to create a receding line toward the nearest vanishing point. You can numerically create a line by clicking once on the document.
