I think this article will help you in creating the script for place family at specific point / coordinates.
and if this article is not full filling your requirement, then you can further post you queries.
Thank you!
But I am not getting it. I am very sorry for the trouble.
Example. I have a patch of point extracted. That path may be a road.
In PC, PT or per station points coordinate. I want to input a Family in each and every point of this path in relation to the line generated.
