2. Key takeaways

1

Each symbol is assigned a manufacturer part: this is what feeds the bill of materials.

2

Components are added one by one or imported from a spreadsheet when the list is long.

3

The Wire Style Manager defines the project's wires; numbering can be redone selectively.

4

Macros reuse a piece of circuit; black boxes represent a specific component with its logical connections.

Tip

Turn any circuit you redraw from one project to the next (motor feeder, 24 V supply) into a macro: you save time from the second project on.

3. Do the exercise

Draw a simple motor feeder:

  • insert a circuit breaker, a contactor and a motor with their manufacturer parts
  • connect them with wires and run the numbering
  • save the circuit as a macro and insert it again on another sheet
✓To check: The reinserted macro creates new component and wire marks, with no duplicates of the original circuit.
