SOME ability to see the nodes or at least determin where they are would be so AMAZINGLY helpful.
If showing them on the ship is a problem, perhaps a simple "inspector" window that would show the X-Y, X-Z, Y-Z values as you move the cursor over the model?
That way you needn't show the nodes, but instead, by moving the mouse around the user can easily determine the rough area to place the node. Like when the "info" panel in Photoshop shows the X/Y values of the cursor.
