Do I need to draw touching edges twice?

[Xzenor]

This may be one hell of a beginner question but I can't find any information about this.. I hope I can explain my issue well enough.
If I have 2 curves. like some funky squares that touch with an edge. and they need to be separate colors so i can't combine them.

Can I use just 1 edge between them? I am now drawing all my touching edges double and they never match because once you zoom in far enough it's never perfect. It seems really redundant to draw those touching edges twice all the time.

Maybe that's just how it should work, I don't know. I'm just beginning , going full n00b..

I’m not sure what you mean by ‘drawing all my touching edges double’. If you’re actually drawing outlines rather than filled shapes, there’s nothing to stop you drawing three sides of a square instead of four.

Yeah I was afraid my explanation would be flaky..

Let's say I want this.

And now I want to fill it.
And I end up with this.

The way I see it, I need to draw that edge where they meet for both curves.. I can't just 'attach' to it so the left part is a whole as well.

I don't know if this solution can suit you but you can superimpose the shapes to avoid gaps or overflows.

*sigh*.. i could have thought of that myself.. why didn't I think of that myself? I don't know.. that would suit me. thank you.
I've just been watching some tutorials, if I really need two sharp matching edges I can start with your solution, divide them and then add the pieces that should be 1 color together again to make them a single curve.

The left part is an open curve that is why you can see white, closing the curve and moving the subsequent edge will get you what G13RL has shown you.

@Xzenor , thanks for the feedback!

Another possibility, if you don’t mind the layers being rasterised upon export, could be to put the shapes in a Group and then add an Outline Effect to the group, see attached video.
