How to join these two curves on all points

[Michael Swengel]

These curves intersect at two points. How can I merge them so that the points at both intersections are actually joined?

If I use "Join Curves" the lower intersection is merged into one point, but the upper is not.

Affinity don't use branches and multiple joined curve.

This is practically none existent in the SVG world. And I´m not sure what you expect from it.

IOW, a node on a curve can connect no more than two curve segments.

That seems silly. I’d like to be able to fill in the closed in area. But I would have to do so manually or re-draw the lines to make that happen? That seems odd.

No, you don’t have to manually redraw anything. Just follow these steps:

1. Copy both lines to the clipboard.

2. Join the two lines and fill the result:

3. Delete the two end nodes:

4. Paste the copied lines on top:

Seemingly silly or not, it has been a standard for a very long time. There is an alternative approach that permits more than two segments connecting to a single node but it has not generated much interest, & almost no apps support it.

No need for that. Not sure you need 2 colored strokes - if not just break it at the crossing point. If yes add a 2 segment stroke above - maybe.

No doubt. It just seems very odd to me. I don’t understand why I can’t tell the program that I want those two nodes to be one. 
 

I’m (relatively) new to vector design, so I don’t doubt what you’re saying. It just seems to me like it could be a lot more intuitive.
