Hello, brave mappers out there!
Currently, I’m working on a map of the suburban railroad network of Frjálshöfn. I’d like to create smooth curves like in Andy’s map of Puerto Real (see here: http://opengeofiction.net/wiki/index.php/File:Porto-Real-urban-rail-network.png)
However, theses Beizer curves are driving me insane! I don’t figure out how to really create smooth, even curves for a 45 degree angle, and I can’t even think of making two or more of these curves parallel!
Is sb as experienced as Andy is and can share the magic to me? Inkscape or Illustrator doesn’t matter, I have both (even if I prefer Inkscape).
Greetings and happy mapping, Markus

In Inkscape, if you turn on the grids, enable snapping, and turn on “snap to grids” then you can make your curves very regular by forcing all your clicks to snap to grid intersections. For example:
Hope this helps. :-)

Ok, I see now what was my error. I did enable the grid, but I set the curve defining points wrong. Thanks!

I have a completely different way of making such maps in Inkscape. On a construction layer that I can switch to invisible before publishing I draw a set of circles in all sizes that I need for the map (e.g., if I have a maximum of 8 parallel lines in my map I draw 8 concentric circles). Then I “cut” all the circles into 45 degree pieces.
Then, when I draw the real colored paths within the map, at each time I need a curve or parallel curves, I take the respective pieces from my construction layer and “glue” them to the lines.
In my point of view this is a bit easier (even though it sounds complicated), especially when it comes to 45 degree line sections, where the snap-to-grid technique won’t work.
This is a map I created using this technique: Public transit network map of Forberg
But thanks anyway for showing the technique with bezier curves.
@Markus: Ich freue mich auf deinen Netzplan. I’m looking forward to your network map!
