> Thanks guys, I learn a lot this week. I was able to apply the rotation from KirkWM suggestion. I added the Curve.CoordinateSystemAtParamter with the 1 parameter… when I isolate that I do get the blocks inserted at the end point, however I don’t see how to add those points to the existing list of points. I did look at the primer list helps but didn’t see how I could add to the my list given how my script was setup. or how I’d add if I started with a new script. I’m still pretty new at this so so…
