Hello. Looking for someone to write a custom auto cad lisp. The function would be to analyze a 3D Polyline for slopes between vertices. The program would trace the 3DP with lines set to specific colors that are predetermined. The final resulting lines would be grouped in cad. I feel the best way to perform this would be with some sort of dialog box where the user can define ranges of slopes and the colors and line-type associated with those slopes. Feel free to ask any questions. Price to be agreed upon after communication.
