Hi TS,

> Any suggestions on the workflow?

Well, I think the main thing would be to try and get the pieces created with good alignment in the first place to reduce the amount of messing around later on.

Can you describe some of the steps that you're doing when creating the curves, which are resulting in overlapping or gapped curves?

Is it possible that you have Object Snap turned off (not highlighted in orange in the bottom bar) ?

You should normally be able to stick things together when drawing them, so I'd be interested to know what is going wrong during the creating of the curves. If I knew what was going on there maybe I could figure out something to fix up that process.
