2. Key takeaways

1

The Flatten Route tool creates a 2D version of the harness and its drawing.

2

The annotation style gives a readable drawing with tables; the manufacturing style gives a flat harness for the harness board.

3

The drawing receives an electrical BOM, a cut list, a connector table and automatic balloons.

4

In manufacturing style, branch bending and orientation are adjusted after flattening.

Tip

Have your wiring shop approve the drawing style before you add detail: depending on how they work, they prefer an annotated drawing or a flat harness.

3. Do the exercise

Take the harness from lesson 4:

  • create an annotation flattening with the electrical BOM
  • add the connector table and automatic balloons
  • create a manufacturing flattening and reorient a branch
✓To check: The cut list includes every wire in the 3D harness, and the connector table every connector.
