I'm trying to call distanceTo from a PointGeometry to a Polyine and am running into trouble whenever the polyline is one I just cooked up. Any pointer on what I'm doing incorrectly would be welcome.
#get the first point feature and the first line feature
poi = arcpy.da.SearchCursor("POIs","SHAPE@").next()[0]
line = arcpy.da.SearchCursor("Streets","SHAPE@").next()[0]
print poi.distanceTo(line) #returns 0.017893575694200557
#get first part of line
part = line.getPart(0)
#get the first two points on that part
p0 = part[0]
p1 = part[1]
#make a new polyline out of those two points
seg = arcpy.Polyline(arcpy.Array([p0,p1]))
print seg.length #returns 0.0017140186696764268, so the segment is there as a polyline
#try to get the distance from the poi to the segment
poi.distanceTo(seg)
This is what comes back:Runtime error
