Help, issues with 3D Layers

I'm trying to make an animation that scrolls, this is the first project I've done in after effects and I'm sure I'm butchering it. I followed a tutorial that said a way to do this was to create a camera and then make all layers 3d but this seems to create a lot of issues. Now I've gotten to the point where I can't create a shape or draw a line on a 3d layer at my current position. If I draw a shape it immeidately disappears, if I click the pen tool and go to draw I get the error sound. The only way I can get new layers on the board are to draw them with 3D layer off, and then once I turn it on the image snaps all the way to the beginning of my canvas, I have to minimize way out and grab the now 3D layer and drag it all the way to my current position...for every layer. Seemingly randomly these layers will simply then stop showing up, where I can see the path and it has stroke but the stroke doesn't display. Not knowng why I just have to do the whole thing over again and then it works...for no reason I can understand. On some shapes I will be able to move some anchor points but other ahcnors points I cannot move...on the same line. And in some instances it will let me move it in one direction but if I move it in another direction it goes haywire (see attached screen grab). I don't understand what's going on here is there something dumb I'm missing?
