How to organize my work - should I draw everything on a single sketch

I want to design a part, but I'm not sure how to practically organize my work around assemblies, parts, sketches etc.

I have a closet with sliding doors. And I also have cats. I want to design a lock to prevent cats from opening the doors. I already roughly modeled my closet and the doors, but now I wonder how should I go about actually designing my parts.

This is what I have: https://cad.onshape.com/documents/058b296ad8467b298f76cfda/v/2f92baf2a0a055ccf3e61217/e/1e0e277fb56e7ecc79f394e3?renderMode=0&uiState=6a4aed73ed1cfc62e2d64c7e

I modeled only one door and I replicated it inside of the assembly. I added sliding mates to be able to slide the doors like in reality. But now I'm not sure how to go about designing the locks, since I don't have a view with all the gaps and distances that I would need to draw the part. All this information is scattered across two part studios and the assembly.

Maybe instead of using the assembly I should simply draw everything on a single sketch? That would mean I would need to replicate bunch of drawings, but at least I would have the dimensions? On the other hand I would still need to see what happens when the doors are moved to different positions, and I would not be able to simply do it on the sketch. Assembly gives me that possibility, but still, only visually and I can not really directly design around it.

Drawing everything on a single sketch probably would work and I would get job done eventually. But it does not feel like the correct solution and it seems like it would be against the "good practices".

Is my thinking correct? What am I missing?

How to make a duct/pipe

I need to 3d print a connector for ventilation duct for a kitchen hood. Long story short contractor messed up, and now I have smaller, not centered pipe in the ceiling, and I want to connect bigger pipe with an offset to it. To complicate things further, because hood will be mounted with an offset, mounting bracket for the hood is partiality obstructing inlet to the smaller pipe, so there is very narrow gap that I have to work with, and I don't want to lose any more air flow doing that. So I plan to cut part of the smaller pipe on the side, to let the connection run at an angle.

This is what I'm trying to connect:

From the side:

From the front:

The "L" line you see is the constraint that I'm working with - it marks the point where the mounting bracket will sit, and I can not go past that.

My initial attempt looked like this:

This is a simple loft - I drew couple of circles along the path and connected them with a thin loft.

But it is missing the cutout in the top narrow pipe. With that cutout I'm unable to connect it and do the loft for some reason. It is also too narrow in the middle, and I would need to find a way to draw guides for the loft.

Do you have any tips on how to do it? What tools should I research and learn? Or maybe what tutorials would help me with this problem? Thanks
