Length
The next four icons on the parameter toolbar permit setting of the pin
length (0, 0.1 inch, 0.2 inch, 0.3 inch). The 0 setting is used if no pin-line
is to be visible, or if, as in the resistor symbol, a pin shorter than 0.1 inch
is desired. In that case the pin is to be drawn with the WIRE command
asalineinlayer94, Symbols.
The SHOW command can be used to check whether a net is connected
to a pin in the schematic diagram. The pin line and the net are displayed
more brightly if they are connected. If a pin with length 0 is used, or if it
was drawn as a line with the WIRE command, it cannot be displayed
brightly.
Visible
The next four icons in the parameter toolbar specify whether the pins
are to be labeled with pin names, pad names, both or neither. The dia
-
gram illustrates an example in which pin names are shown inside and
pad-names outside. The location of the label relative to the pin is fixed.
