Comments
This function is valid for the following annotation objects:
Curve
Closed Curve
Freehand
Freehand Hotspot
Polygon
Polyline
In addition, the Automation object stores node settings along with the other object default settings

Note: |
The last node is always shown. Therefore, using a large value for uGapNodes will probably result in only the first and last nodes being shown. |
