Hi Marc -
I wasn't aware you could elevate in 3D window via ctrl+9 either! And......I have imtermittent results. For me it worked best, on a roof anyway by selecting it at the pivot line, ctrl+9, then z, input and it usually worked..........although I paid attention to what coordinate was highlighted, and I love this about 10, simply tabbing through them until I land where I want.
I have and will probably continue to use my tracker for this. [see attached settings] The moment an object is selected, and not before, tracker appears, then I tab through, input, enter and it's done. Frequently moving, or starting to move the object in the direction I want, i.e. up or down yields best results. as always multiple ways to skin that cat............
