Simple import text.txt files of polygon co-ordinates

Help_Tom

Hi,

Thanks for this design program it is a huge help to my studies.

I have a lot (100's - 1M's) of text.txt files which contain the tab delimited x,y co-ordinates of polygons. Is there a simple way to read all of these text.txt files in without any understanding of Ruby or Python (Python I have a little understanding but I would like to avoid Macro editing if possible) and make the shapes.

Many Thanks,

Tom

Hi Tom,

I'm sorry, but this is exactly the thing Ruby or Python was made for.

You can essentially edit a drawn polygon coordinates in a text edit box. You could paste the coordinates from one Polygon into this box so make the polygon look like the one you want to have. But I think you'll want a script that reads all your files and turns them into polygons.

I can give you a skeleton of such a script:

# Assume we have a layout loaded and a layer - let's say layer 1, datatype 0 - is prepared to 
# receive the polygons ...
ly = pya.CellView.active().layout
layer = ly.layer(1, 0)   # layer 1, datatype 0
shapes = ly.top_cell().shapes(layer)

# assuming files is an array containing all your file names, and read_file is a function which reads
# a file and returns an array of coordinates [ [x,y], ... ] 
for f in files:
  points = read_file(f)
  polygon = pya.DPolygon([ pya.DPoint(p[0], p[1]) for p in points ])
  shapes.insert(polygon)

Thanks Matthias. I will look to understand the programmatic coding.
