When calling out where utility crossings are located (the utilities are drawn as polylines and NOT 3D objects) along a pipe in profile view, rather than trying to find the crossings on the site and then manually adding a callout in the profile, I want to be able to quickly identify where the crossings are in profile and plan view. To do this, I need help creating a LISP that draws a polyline connecting a selected location along a pipe network (in plan view) to the corresponding location in profile view. Please let me know if you need more specifics!
