Doodle Object
The Doodle object contains all doodles that have been created. Several other functions are also available, among them the Description text field that can be dragged & dropped into the Viewport as a HUD to augment any doodles in the Viewport.
The Doodle object can be more-or-less hidden and unhidden using the Display tag's Visibility parameter.
Tip:Make sure to delete any existing images and click on the Remove Unused button before saving presets (Object Manager: File / Save Object Preset) for the Doodle object.
