Nets are always given an automatically generated name. This can be
changed by means of the NAME command. Nets with the same name
are connected to one another, regardless of whether or not they appear
continuous on the drawing. This applies even when they appear on dif-
ferent sheets.
If a net is taken to another net, a bus, or a pin connecting point, the net
If a net is taken to another net, a bus, or a pin connecting point, the net
line ends there and is connected. If no connection is made when the net
is placed, the net line continues to be attached to the mouse. This behav-

end net and bus option). If this option is deactivated, a double click is
needed to end a net. Nets are shown on layer 91, Nets.

Do not copy net lines with the COPY command. If you do this, the
new net lines won’t get new net names. This could result in unwanted
connections.

If the MOVE command is used to move a net over another net, or over
a pin, no electrical connection is created. To check this, you can click the
net with the SHOW command. All the connected pins and nets will be
highlighted. If a gate is moved, the nets connected to it will be dragged
along.
