I created the following program to draw a point at each intersection between tow lines i want to update it to draw the edit points when i have two polylines or line polyline ***** (defun c:in2l ( l1 l2 intersection a) (setq l1 (car (entsel "\npoligne 1")) l2 (car (entsel "\npoligne 2"))) (setq intersection (inters (list (car (cdr (assoc 10.

Closed Polyline Between Two Polylines Autolisp Visual Lisp Dcl Now check if the points between every 2 consecutive intersections of one polyline are inside outside the other polyline. based on the alternation inside outside, you can establish the relative position of the 2 polys. now you only need a good inside p function 🙂 i guess you'll find some in this forum. see the image for demonstration. Hi, if it helps: start command region and convert your polylines (have to be closed) to regions. then you can run union to get them dissolved. disadvantage of this method: sometimes it's difficult to get the resulting entities back to polylines. advantage of this methods: regions know islands (polylines don't). If polyline for calculation don't touch reference border polyline making "v" shape near border pline and fuzz is higher than lower vertex of "v" shape, offset pline will intersect pline for calculation 4 times on that segment, and therefore, you'll have 2 points for picking executing boundary poly command. This one lets you select to closed objects and will keep the area that the two objects share and trim away the rest. even though this can be done by using the trim command and hitting <enter> twice, this routine is nice because it works great for cluttered areas…. here’s how: plint <enter> to start (polyline intersection) select the closed.

Polylines. the lwpolyline (light weight polyline) entity, or "optimized polyline," was introduced with release 14. a lwpolyline is defined in the drawing database as a single graphic entity. this is different than a standard polyline, which is defined as a group of subentities. lwpolylines display faster and consume less disk space and ram. There is a tool available to create a centerline between two features: polylines can be averaged by using the pathaverage.lsp file (attached): download the attached pathaverage.zip file and extract it. in the autocad command line, enter the appload command. select the pathaverage.lsp file and click load. enter the pav command.
