I have a quest where I create an invisible placeable container on the wall (Z coordinate 2 or 3).  If the PC places a gift painting (in this case, Portrait of a Goose Girl) into the object, it self-destroys and spawns a painting (custom placeable) in its place. The script (below) works masterfully and the painting appears - the only problem is that it appears on the floor.  Not exactly good placement for a "hung" painting.

I have even tried putting a placeable shelf under it to "catch" it if the CreateObject function puts it in place but it falls because there's nothing beneath it, but it appears to be generating at Z coordinate 0 rather than moving through the shelf.

Does anyone know if that's how CreateObject works? It would make perfect sense, but it would make this quest rather pointless.

If it must spawn on the ground, is there a way to raise an object?  Most of the "move" functions seem to either move an item from one character to another or move a character to a waypoint.  Thanks,

Is this in your own module, or an add-in to single player? If it's in an area you can edit, it would be easier to pre-place the painting, set it as innactive then activate it when you deposit the painting.

If you need to spawn it dynamicaly, my guess is that GetLocation by default returns a safe location, which is a location on valid pathfinding ie the floor. I can't remember if there's an optional paramater to not get a safe location but I suspect there is.

If there isn't, try SetPosition, using GetPosition(OBJECT_SELF) as the position paramater. Make sure to move the destroy object call after the set position. If the placement is still a little bit off, you may need to find the exact coordinates you want the painting to be at, create a position vector with Vector(1.0, 2.0, 3.0), substituting your coordinates, and pass that into SetPositon instead.
