Center line

Center line

(OP)
How can I draw a center line of canal. My canal is not smooth and have a lot curve . If I have two side of canal how can I draw it fast. Now I draw a lot of section lines  perpendicular with bank of canal( between 30m example) and make a center line base on this.
Do you have any advise? If I do manual, when I want to change center line it take time.
If you have any recommend, you can show me.

Thanks a lot

RE: Center line

If the canal sides are equidistant from each other all along its length, you could turn the canal side boundary to a polyline and then offset it the correct distance. Otherwise you would have to make a complicated algorithm to pick points between the sides and then calculate perpendicular distances and estimate the center path. I do not know of any routine that could do this.
