Black boxes
A black box is a generic symbol that can be used to represent any device,
acting as a time-saving feature where a new unique symbol is not required
or there is no time to create one. Black boxes are rectangular and can
have editable pins associated to them.
Black boxes are inserted in Schematic
or Mixed scheme drawing types.
Connection points of the black box
On each intersection between a wire and the black box outline, a connection
point is inserted, it represents the device terminal. According to the
configuration settings, you
can have a basic connection point (the terminal number is a text) or an
oriented connection point with attributes.
There are two ways to insert a black box.
