How to set the ViewSection BoundaryBox?

[ehall8CEK4]

I am making a plugin that will create a ViewSection from an ElevationMarker that shows a specified wall.  I would like the plugin to automatically crop the ViewSection so that only the given wall is visible.

I have attempted this by getting the BoundingBox of the wall from the newly created ViewSection, and modifying the .Max & .Min slightly before setting the ViewSection's cropbox to it.  However, whenever I do this, I get an "The CropBox is empty" error.  I disable the cropping of the view before before getting the wall's BoundingBox, so the wall should be visible.

Creating a BoundingBox from scratch also gives me a "The CropBox is empty" error.

Also, how does the BoundingBox of the ViewSection relate to the BuiltInParameter.VIEWER_BOUND_OFFSET_FAR parameter?  It looks like both should be able to set the depth of the view, but does one take precedent over the other?

Does my sample code to create section view parallel to wall fit your needs?

Unfortunately I don't think I can use that method to create an ElevationView.

I might finally understand where my problem is stemming from.  View BoundingBoxes use a different implementation of the XYZ coordinate system than normal BoundingBoxes.  X is the left and right coords, Y is the height, and Z is depth.

Do you know a way to take a normal BoundingBox and transform it into one that can be used in a View BoundingBox?
