I'm trying to print the above toy plane.
Is there a way to automate getting the / a flat surface to the bed without having to magnify and rotate each part?

It is very easy to use the function in menue EDIT > Place Surface on Bed.

If it works with groups or multi-selections I don't know, try it. Otherwise it needs only 3 mouse-clicks for each one.
