Drawing from an Existing Line or a Device Pin
A line can be extended from the end of an existing line or device pin using
the arrow ( ) cursor. Click and hold on the end of the pin and drag away
from the pin. A pair of right-angle lines will follow the cursor away from
the pin as long as the mouse button is pressed. Releasing the mouse button
makes these lines permanent. If the end of the line (i.e., the point where the
mouse button was released) touches another signal line, a connection will
be made at that point.
Alternate line-routing methods can be activated by pressing the and
keys, as follows:
The key inverts the order of line drawing, and the key
switches to three line segments with a center break. The key con-

NOTE: Holding the key while clicking will inhibit checking for pin

position without affecting any existing connections.
Creating an Unconnected Signal Line
The Draw Sig ( ) tool can be used to create an unattached signal line, or
to extend an existing signal. Simply click anywhere in the schematic and
drag in the desired direction. Unlike the Point mode drawing method,
