Thanks for checking – I own multiple games with tens of millions of visits total. 
I use a plugin to view part orientation because changing motor surfaces is too time consuming.
As mentioned before you should totally support the existing feature request on this. I did not say that this shouldn’t be in Studio. I only said setting hinge surface as a way of viewing part orientation is spacebar heating. So let’s keep things within context and not dismiss someone’s opinion as a lack of experience (especially since I have more experience with the engine than you do).
