Export Polygon Points to csv in correct order
-
I have asked this question before but I guess its now somewhere on the bottom of the pile and I have not had a response yet
Before I abandon this idea I would like to give it one more try:I need to draw polygons (trace a scaled map) and export co-ordinates in the correct order to a csv.
I found this great plugin from TIG (Export Vertices to CSV), which works fine, except it dumps the coordinates not by following the line segment order. I am trying to read the generated point file into a python script that redraws the polygon for me... but I get quite a mess this way...Thanks in advance!

What is the "correct order"? How is that determined?

Thanks very much Dave!!, I now realize that it is indeed a bit of a shady definition!
I just meant that each polygon has a begin and an end-point and the "correct" order is getting the sequential line segments in that order. So for example for a polyline consisting of 3 line segments I would get 4 co-ordinates in order that makes up the polyline:x1,y1 start line segment a
x2,y2 end line segment a, start line segment b
x3,y3 end line segment b, start line segment c
x4,y4 end line segment cI think this is the only way to rebuild a polyline if all you have are the co-ordinates.
