how to get the drawingviews that not showing(not placed)?

[1354448288]

I wonder if there is a solution to get the drawingviews that not showing (or not placed) in the sheet.

I tried to use drawingview.getvisibility, but it should be used to check the entities whether to show, not the drawingview.

I don't really get what you mean with shown (and especially not placed) about a DrawingView, if you mean suppression instead this property is the one for you: DrawingView.Suppressed.
