You can use the SelectionChanged.
If you want to alter the slection, just turn on a flag to detect being called again or temporary change your SelectionChanged event handler.

Hello, Alexis,

having problems with Navisworks documentation. could you please, point me to SelectionChanged event description.

Dot Net API reference is mentioned Autodesk.Navisworks.Api.Takeoff assembly but not sure if it is appropriate for the current view item selection event.

Thank you

Hello, Alexis,

discovered from sample code where is such event subscription located:

DocumentCurrentSelection class, Changed event

And it is working fine to select entities in Navisworks current view.

Regards,

Gennady

Using SelectionChanged does not allow to modify the selection because this is in readonly.

The way I do it is by creating a InputPlugin, in the MouseUp function, I get the ModelItem user clicked with view.PickItemFromPoint(x, y).ModelItem then change it acording to my rules.

Then return true to block Navisworks's selecting process

If you did nothing, return false to let Navisworks select stuff.

Regards

Good Technique.
For similar situations, in our plugin I use a different trick: on SelectionChanged, I set up internal action that is executed in next call to our plugin OnIdle.
