The direction of a pin can be specified manually or determined automatically. The envelope of the symbol is formed internally for the automatic determination. The automatic pin orientation is determined by the outer edge of the envelope at which the pin is positioned, i.e. a pin on the outside right is assigned the pin direction– right.
The pin orientation also determines the text direction for the pin number and pin name.
Note
Normally, the pin numbers and pin names are aligned the same way. However, if the pin orientation is automatically recognised as top or bottom, the pin number is vertical but the pin name is horizontal. This property is used for auxiliary contacts arranged at the side.
