Sometimes it will display this blue square around a point and snap a new line to an existing point on a line in a sketch:
But then other times it shows this X over an existing point and won't snap to it. What causes the X to appear and not snap to an existing point? How can I fix it so it shows the blue square and snaps?
In the second image is the existing line in the same sketch? Is the problem repeatable, can you export the design as an f3d and attach here or can you make a screencast?

Another thought, have you moved the line off the XY sketch plane? If you don't have 3d Sketch enabled and the line's not on the sketch plane snaps will not work.

You have a lot of sketch entities that are way above the sketch plane, is there a reason for this. Snapping to endpoints etc. will only work on these entities if you have 3d sketch enabled. If you really need the sketch items on 2 levels you will be better off using 2 sketches and using an offset plane to give the difference in height.

Another tip. You will find this far easier and quicker if you extrude into bodies. Make one body in a component then copy and position the components. Selection in the manufacture workspace will work far better using the edge of a body rather than a sketch as well.

No, that would be a mistake on my part. In making those sketches, I click the "top" view and then just add sketch lines. What would cause some sketch entities to deviate off the sketch plane?
Only way I can think of is if you used Move to make copies and moved the Z height by mistake.

@tomFHWKA You will find this a lot easier if you keep the sketch as simple as possible then fillet an extruded body. As I said above use components then copy the components. Far easier only sketching once, also easier to fully constrain the sketch so edits will be predictable. This is one of your parts with the sketch simplified. Did you know the 2 edges on the left are not aligned? I've attached the design.
Here's a quick screencast on copying and positioning the components.

The simulation problem is because you selected most of the lines individually not as a chain. Here's a screencast showing how to select if the whole chain doesn't select at first. Note white dots mean you have unjoined sketch elements so auto chaining will probably fail. Also show it just works with bodies, the CAM will always get the offset side correct using a body.
