Driving Camera with API

[spencer]

I'm trying to add camera controls through the Inventor API but am not having any luck getting the camera to move whatsoever. Everything I've tried results in nothing happening (Not even an error cropping up), and I'm wondering if the API controls are simply not working for some reason.

Ex.

inventorApplication.ActiveView.Camera.ViewOrientationType = ViewOrientationTypeEnum.kFrontViewOrientation
inventorApplication.ActiveView.Camera.Perspective = True
inventorApplication.ActiveView.Camera.Fit()
inventorApplication.ActiveView.Camera.Target = inventorApplication.TransientGeometry.CreatePoint(0, 0, 0)
inventorApplication.ActiveView.Camera.Eye.TranslateBy(inventorApplication.TransientGeometry.CreateVector(0, 0, -(inventorApplication.ActiveView.Camera.Eye.Z) + inch2database(72)))
inventorApplication.ActiveView.Camera.Apply()

The above will do absolutely nothing, nor will any combination of them do anything. The only things I've found so far that do work are:

inventorApplication.ActiveView.GoHome()
inventorApplication.UserInterfaceManager.ShowCleanScreen = True

Am I missing something here?

Thanks and regards,

That second link told me exactly what I needed to know, 

"The behavior of the View.Camera property is that every time you call it, it returns a new camera. This behavior makes it easy to run into a very common problem when working with cameras."

That should probably be included in the API docs somewhere, regardless I've got it working now.
