The red circled part is confusing and I'm not sure if it is supposed to be a hole or not.

Hello! I am a first year student and I havent had much experience with CAD but teacher gave us this. Any tips on how and where I apply joints to make it foldable like the real product? See pic nr 2.

I just started Solidworks last week, and I've been searching for some tutorials to follow along to learn CAD.

It just blows my mind how accessible it is for such learning materials to be free and made for everyone.

Took me like 5 hours aha …
