Hi! Still a bit of a noob here, but I can't seem to find a solution for this problem on my own.
Below you can see a model I created. Although it looks like it's a solid 3D model, it's not (see the second picture for the rotated version). I started sketching it in 2D, but then I couldn't figure out how to create the rest of the 3D figure by pulling, so I started sketching the linkework first.
Here's what it looks like when tilted, so you can clearly see it's just linework.
If anyone could tell me how to create a solid 3D out of the 'frame' I made, that would be awesome! I've tried several things, but none of them worked.
