[quote user="Robert Hook"]I will file a defect to correct to ElementHandle FindByID that is exported in DgnPlatform\ElementHandle.h[/quote]
The two overloads of FindByID() are members of EditElementHandle, not ElementHandle.
Why isn't there a ElementHandle.FindByID()? There's an ElementHandle constructor that takes an Element ID. What's the difference between constructing from an ID and FindingByID?
