How to specify settings for BOM position flags
1. Click File > Settings > 3D Documentation > BOM settings. The BOM settings dialog box opens.
2. Enter a Start and Step value under Numbering.
Start represents the number that the first position flag will begin.
Step represents the number increments between the position flags.
3. Choose Spider or Stub under Appearance.
Spider creates a leader line from the center of the label to the reference.
Stub creates a leader line from the "tail" of the label to the reference.
4. Select the Highlight color for Unassigned and Assigned parts.
Unassigned parts do not yet have a position flag label.
Assigned parts already have a position flag label.
