@Alan - yes I think so I fundamentally want to take some strands and interpolate them between two positions. I'd like the second position to be determined by another strand in another pointcloud.
This is how it works using a curve as the second position. But ideally I'd like to swap the curve for a strand. http://s30.postimg.org/st7dsynkx/strands.jpg @Graham - thanks for that but I got totally lost........

However, if all you really need is the closest position on the strand (i.e. not a “real” location for looking up other data), and it’s good enough to treat the strand as a polyline (i.e. not smoothed), then you can cook up something using Get Closest Point to Line Segment. I don’t have a scenario to test this in so there may be errors, but I’m thinking about something along the lines of the attached pic. If you want to do something fancier like get StrandColor at the closest position, then you’d need to figure out which segment contains the closest position, what %age it is between the two neighbouring StrandPosition values, and interpolate between the two corresponding StrandColors based on that. gray From: [email protected] [mailto:[email protected]] On Behalf Of Alan Fregtman Sent: Wednesday, March 12, 2014 3:16 PM To: XSI Mailing List Subject: Re: Get Closest Location...... on Strand If such a thing existed, what are you trying to get from it? Are you trying to find the closest position on a strand to a given point?
