sample_MPoly2.dwg Hi all, I have six polylines, one of them is closed. I need to create vertices on a closed polyline. The sample drawing is attached. The vertex coordinates to be created are the coordinates of first vertex of other polylines. So far I only managed to store the coordinate of starting vertex of one polyline. (vl-load-com) (setq s1 (car (entsel))) (setq pl (vlax-ename->vla-object s1)) (defun vlax-list->2D-point (lst) (if lst (cons (list (car lst) (cadr lst)) (vlax-list->2D-point (cddr lst))))) (setq vertCoord(vlax-list->2D-point (vlax-get pl 'Coordinates))) (setq vertStart (car vertCoord)) Appreciate your help. Thank you

Hello there, Merry Christmas! I am new in LISP and I don't know where to start from. For clarity, please refer to the snapshot provided. I am not quite familiar with AutoCAD terminology though, but I'll try to explain my problem clear. Basically, we have polylines and points having their coordinates (these small blue rectangulars). What we need to do is: Find the closest on the polyline from the "blue rectangular" Create the vertex on THAT point Export to Excel files the following parameters: number, Coordinates of each vertex, distances between them, '1' if the line contains newly-created vertex The output files are expected to look like: 1. XY_Coords.xls: Node X Y 1 359.898 163.788 2 358.514 164.124 3 358.423 164.131 4 358.354 164.119 5 358.26 164.07 6 358.198 164.005 7 358.153 163.91 8 355.136 152.963 9 354.962 152.691 2.

Hello, there, I am trying to find a LISP routine which will find the closest point on a polyline from a selected block reference. This routine finds the closest distance between two objects by selecting both objects, but it does not seem to work with block reference. After it finds the closest point, how to create a new vertex on that point? Thank you in advance Best wishes, Jes G
