As Autodesk ADN Support cannot help.
I share a question regarding the API Design Review.
Viewer.OnSelectObjectEx Event - This event gets fired when an object in the DWF is selected.
pHandled - An object expression that specifies an IAdToggle object allowing the client to handle an event (that is, override default behavior)
We understand your purpose and execution.
As per the attached video, in Find, when we click on an object, it is selected and shown in yellow.
Doubt: We need to know which set of commands or functions perform focus/zoom on the selected object?
