Hans, I agree with you, SH3D is the easiest to use 3D design program! But not an ideal unfortunately
. People often organize a Usability testing for big projects: create several GUI, invite several groups of people, provide them tasks and see how people do it. Whether they will achieve success or not, how fast, etc... It costs a lot of money and takes a lot of time and therefore doesn't make sense.
I see how my friends and my mother work with SH3D: they create walls, create room, then add doors. First time I did the same.
