How do I get the parts at the right angle in the Assembly?

Hello,
After designing the folding table, I would now like to try my hand at a folding chair.
And that's where I run into the problem that the legs are bevelled at the bottom. How do I get them at the right angle, and not just the legs but also the struts that connect them as
I have an empty space in the assembly without a reference plane.

Kind regards

If you look at exercises in the Learning Center, like this one
https://learn.onshape.com/learn/course/introduction-to-assembly-design/mating-parts/exercise-mating-parts?page=2
you'll see that it is best practice to model related parts in one Part Studio. Then, the easiest thing to do is just drop them into an assembly and group them.
Agree, best to model a chair in one part studio.
To fix what you have, place a mate connector on the origin of the asm. This will be the ground, and center of the chair. Then on the studio with the main leg, place a MC there, where the feet touch the ground, but offset half the width of the chair. Then insert this leg into the asm, and fixed mate its MC to the MC of the asm. This will set up the whole chair to be proper in the asm.
From there, assemble the rest of the chair parts using fixed mates at each of the mortise and tenon joints.

The fun part will be it being a folding chair, so nothing is really 'fixed' to the ground. This might be a real nice excercise to learn all the different kinds of mates! ;0)
Hint: The magic sauce here is going to be how the parts and subassemblies align themselves. To make this work, you will need to build subassemblies like these (add the missing struts) and then find the relationship between them:

I gave up trying to put the pieces together; it's too complicated for me. I drew all the pieces so that I could make the chair.
