Hi, I am implementing a WPF window that I want to allow the users to select an element from Revit model, then a preview for only this element's top view would be shown to the user. However, I also want the user to interactively select the sides of the selected element from the top preview for further processing.
I can list the sides of the element's geometry programmatically by the API, but then the user won't be able to interactively identify a single side for further processing.
I appreciate your guidance to me by any online sample code or keywords to direct my search to achieve this functionality.
Thanks in advance
