I design sofa beds and one of my my bigegst problems doing so is transforming what happens in reality to SW.
You can see on the attached picture that the part shown on the PrtSc with the 3 circles isnt flat with the sofa structure.
I want it to be able to twist like it does in reality. I've been experimenting with coincident mates: using mid centered points on the holes of this part and making them coincident with an axis on the other parts.. But it doesnt twist like it does on the picture!
Is this possible? thank you
