HI,

I am trying to select specific curves by using their area centroid, which is basically three coordinates.

Ive managed to obtain these coordinates using bounding boxes, given these curves are not sitting on cplanes.

However i cant seem to select specific curves by using just the z coordinates. Basically i can put them into lists based on length etc, but not sure how to work with coordinates. Here are my current notes

from Rhino.Commands import Result

from Rhino.DocObjects import ObjectType

import rhinoscriptsyntax as rs

from scriptcontext import doc

layer_objs = rs.ObjectsByType(4,True)

if layer_objs:

#create an empty list

mylist=[]

for obj in layer_objs:

#find curves among the objects

if rs.IsCurve(obj):

if abs(rs.CurveLength(obj)<100):

#curve meets selection criteria, append to â€śgoodâ€ť list

mylist.append(obj)

rs.UnselectAllObjects()

#bBox = rs.BoundingBox(mylist[0])

#CURVE1

#rs.UnselectAllObjects()

for i in mylist:

bBox = rs.BoundingBox(i)

cent = [(bBox[0][0] + bBox[6][0])/2,(bBox[0][1] + bBox[6][1])/2,(bBox[0][2] + bBox[6][2])/2]

print cent

rs.AddPoint(cent[0],cent[1],cent[2])

newlines = rs.SelectObjects(mylist)

if newlines:

s=[]

for line in newlines:

if rs.IsCurve(line):

if abs(cent[2]< -11):

s.append(line)

rs.UnselectAllObjects()

rs.SelectedObjects(s)

I keep getting the error: expected an indented block.

Help would be appreciated, thank you.
