AutoCAD Lisp Routines | Enhance Your Drafting with Free Utility Functions related to Polylines

Welcome to our video tutorial on using free Lisp routines for utility functions! Today, we'll explore five powerful utility Lisp routines related to polylines that can significantly enhance your drafting workflow for engineering drawings.
Before we dive into the routines, make sure to visit our Free Lisp page on our website to download these Lisp files. Simply register and log in to get access. Once downloaded, place the .FAS or .DES files in any folder of your choice. To load these programs, use the 'Appload' command in AutoCAD.
1. Reduce Polyline Vertex
"Our first Lisp routine is 'Reduce Polyline Vertex'. This tool helps reduce the number of vertices in a polyline, which can make your drawing size smaller and improve performance."
Load the program using 'Appload' and type ‘RDPW’ at the command prompt.
"Here we have a polyline with 42 vertices. Using the ‘RDPW’ command, we can specify the distance at which we need vertices. The new polyline created has only 18 vertices, placed at regular intervals."
2. Insert Vertex Along a Polyline Using Text Position
"Next up is 'Insert Vertex along a Polyline using Text Position'. This Lisp routine allows you to add vertices to a polyline at the positions of text entities along it."
Load the program using 'Appload' and type ‘Iver’ at the command prompt.
"Select the polyline and the text entities. After executing the command, new vertices are inserted at the text positions."
3. Quality Check Polygons
"Third, we have the 'Quality Check Polygons' routine. This tool helps you find close polygons and ensures your drawing is accurate before exporting to a GIS system."
Load the program using 'Appload' and type ‘FCPly’ at the command prompt.
"Select the polylines, and the program will mark the area of each polygon at the center, exporting these areas to a CSV file and marking all open polygons."
4. Move Text Objects Along a Polyline
"Good drawing representation is crucial. The 'Move Text Objects along a Polyline' Lisp routine helps you align text on a polyline or at a fixed distance from it."
Load the program using 'Appload' and type ‘Magnet’ at the command prompt.
"Select the reference polyline and the text entities to be moved. The 'Magnet' command will align the text entries onto the polyline."
5. Create Coordinate Table
"Lastly, we have the 'Create Coordinate Table' routine. This tool creates a coordinate table for 3D and 2D polylines."
Load the program using 'Appload' and type ‘Cotbl’ at the command prompt.
"Select the polyline and choose a point to place the coordinate table in the drawing. The program generates a table with point numbers, X, Y, and Z coordinates."
We hope you find these Lisp routines helpful for your projects. Don't forget to download these free Lisp files from our website. We also customize Lisp routines as per your requirements. If you need a custom Lisp, send a sample drawing to [e-mail].
