API to find 3D Annotations in 2D Layout?

[solid7]

3DX 2017x

I'm trying to make a check tool, that will compare the parts in the tree/BOM to the views on the layout, to ensure that our captures/view filters have captured all of the part numbers. I have already got this working on the 3D side, so that the user gets a validation that all parts are annotated, or that some need references. However, just because they get put into 3D, does not mean that they show up in 2D.

I though that I'd be able to capture the info using the object 'DrawingText' - but alas, it's only for true 2D text.

So the question is, is it possible to get ahold of the 3D annotations from the layout?

I have checked every object available under "Layout2DView", but I wouldn't be surprised to learn that this is something that has to be accessed by a mask string.
