Hello, I have recently purchased the pro version in order to use the API. I have begun to write a standalone C# application (not an addin), and have been able to do many things so far such as drawing lines, creating blocks, etc. I am not, however, able to select items using the SelectionManager. (I am able to select items by setting item.Select = true, though)

I have tried SelectByPoint, SelectByWIndow, SelectByPolygon, and SelectByCrossline, none of which are working. I have read through the documentation and passed in the correct data (and the methods return true), but there are no examples in the help docs.

I do not have any selection filters active, and all i'm just calling the select method, and that's it. If there is something else I need to be doing to select, I'm not sure what it is.

If anyone has any help/ideas/working examples that would be greatly appreciated. Thanks!
