Connect

To use the Connect tool, click on one end of an open path (the cursor will snap to the endpoint with a ring annotation), and then click on another end. The path or paths do not need to be selected.

Connect Tool Tangent Connection Example

By default, the new segment will join in a tangent (smooth) manner, but by holding down Option/Alt, the tool can be made to connect perpendicularly (at a 90° angle).

Connect Tool Perpendicular Mode

If two paths with different styles are connected, the single connected path takes the style of the path which is lower in the stacking order.

Before releasing the mouse button after clicking on the second endpoint, the cursor may be dragged to adjust the handle lengths of the connecting segment. Dragging upwards or downwards changes the lengths of both handles equally; dragging left or right shifts the “balance” between the handles (making one shorter and the other longer).
