Ori

The origin, denoted by a small box with a dashed outline, is the

center point that the schematic editor uses when rotating a part

instance. By convention, the origin of each symbol in the

symbol library is placed at the point of connection to the upper

far left pin on the device.

To define the s

mbol ori

From the Graphics menu in the symbol editor, select Origin.

Double-click the connecting point of the pin that you want

to use as the origin (usually the upper far-left pin).

Boundin

box

The bounding box, denoted by a large rectangle with a dashed

outline, defines the selection area for a part instance on the

schematic. By convention, the bounding box encompasses the

symbol graphics and pins.

To make proper connections, the bounding box must contain all

visible pins. If you try to save a symbol that has pins outside the

bounding box, the symbol editor issues a warning message.

To make selection of closely-spaced part

instances on a schematic as easy as possible,
