Dear users,
I have a list of DXF Polylines data, and I would like to extract the
coordinates {x,y}_i out of each sublist (code 10 followed by x1, 20 by
y1, and again 10 by x2, and so forth), but the length of the 10-20 run
is general. I've read about Repeated pattern, but still can't extract
the whole run.
I would like to solve this with patterns.
