The characteristics of these beamlines are summarised in the table below and their location shown in the schematic drawing.

In a schematic drawing, for instance, line segments and curves might be primitives.

There were no plans, blueprints, or schematic drawings.

Schematic drawings intended for maintenance may have the principle signal paths highlighted to assist in understanding the signal flow through the circuit.

They were frequently used in production of schematic drawings, maps, and printed circuit board artwork, as examples.
