I was attempting to create my sliding door for my game when I ran into a problem. The problem was that I had no clue of which side the part was facing on. Was it the left? Was it the right? I do not know how to see the front surface since they removed the surface property.
Actually I don’t have it too, so, I found a method where I put the part, go to Model near Home, then go to Surface and select, for example, glue; then click a face of the part and when you will go to the proprieties of the part then you can finally see Surface Input and Surface. I hope I helped you in some way, I’m sorry if I don’t have the actual solution but this is what I do
