I have a series of x,y co-ordinates converted from a .ply file. I was able to extract the file into a suitable x,y format for arcmap, the issue I have is that they are co-ordinate points representing 90 polygons. So in arcmap I have the coordinates for polygon 1, then a series of null rows, then co-ordinates for poly 2 etc. I have been manually entering the polygon number using field calculator but with 91 it is taking me a long time, so I thought I could use the sequential calculations script. Each null row is the same number of rows between each poly (7). so what I need is a script that will update a field with polygon 1, skips 7 null field rows, poly 2, etc etc.
The other issue is that the number of points in each polygon is different, so the only way to differentiate each polygon is the null rows in between.
I meant this script in particular
Accumulative and sequential calculations
