Adding Curve between 2 other curves

[em.kae.be]

I'm trying to create a curve evenly distributed between two other curves, but can't figure out how to do it in Affinity Designer on my iPad. I've attached an example of what I'm trying to do. I would like to have the red line to be exactly in the middle of the two other black curves.

I'm a little new to Affinity Designer. I know this can be done easily on Illustrator using the Blend Tool, but I don't believe that exists on the iPad version of Affinity Designer. Any suggestions/help would be appreciated.

Hi Em.kae.be,

Welcome to the forums

As far as I'm aware there is no automated way to do this I'm afraid.

Thanks

@Callum thank you for the reply back. That is unfortunate that this can't be automated. Any tricks you or anyone else can provide to make it as painless as possible? Given this particular situation, I can't even easily scale down or up. 

Thanks again for the reply back.

Hi em.kae.be,
You can try to duplicate one of the lines, give it a large stroke until the part that extends in direction to the center of the two lines gets ...well...centered between them,  then go to menu Layer > Expand Stroke, give a stroke to that expanded shape and remove its fill then break it so you end up with line part that's centered between the original lines. It won't be perfect and you may to tweak it a bit but it's a start. Similar operation can be done with the Contour Tool in v1.9 Beta.

@MEB thank you for the suggestion, I did try that approach initially. In my first attempt the new curve was off by a lot and not close to being in the middle. I was hoping that someone with more talent than me had an easier approach. I guess it's just tweaking a bunch once something close is created. 

Thanks,

I'm afraid there's no specific tools for this (like a Blend Tool), sorry.

I found this discussion because I was looking for the same thing. I was just wanting to put cut lines on an A4 page to cut it evenly into 30 strips. In Illustrator, I'd just draw a 30 row grid with the grid tool, or blend 2 lines across the page with 29 divisions. (30 seconds to do it). Designer has forced me to manually duplicate a line 30 times and then align & distribute them. A real pain, especially since I seem to be constraining my movement to a 15 degree angle and I can't find out how to change my move angle contraint settings.

Anyway, here's a simple work around for your particular challenge. It uses the appearance panel to layer multiple strokes on each other. I made a video because it's a mission to try explain it.

@Stephen_H thank you for sharing the video. Funny enough I started this approach after watching this video, but I was working outside in vs inside out, which is what you are showing. My approach wasn't getting me the results I was looking for, but I think yours will.

Thanks again,

Use the guide manager and enter directly the number of rows you require as a start perhaps?

Alternatively use Power Duplicate and the transform studio for exact measurements and angles.
