How to draw a center line between two lines

[genosyde]

Hello devs.
I'm currently looking for a way to draw a center line between two lines(Line, PolyLine, Spline).
It took a lot of time but couldn't find it yet.

If you select the two lines above and below,
I want to make a program where the middle line is made.

Please let me know what to look for and if there is any code to reference.

Thank you. ^^

hi@genosyde 

in case of two polylines, you can simply iterate through each vertix and create a temp line between this verix and the nearest point to second polyline then store the mid-point of this temp line, and do so for second polyline, finally connect those mid points,

in case of arc you can convert to a polyline (based on your accuracy),
