AutoLISP Routines

PDIST labels a polyline with running distances. Pick one, and it writes the cumulative length above every vertex — zero at the start, then the distance travelled at each corner, all the way to the total at the end. It is chainage annotation for anything measured along its length: a road centreline, a pipe run, a fence, a boundary traverse. It is by Art Whitton, and … [Read more...] about PDIST LISP: Label Running Distances Along a Polyline

SPER draws a line perpendicular to a spline. That sounds simple until you try it: AutoCAD's perpendicular object snap works against a spline, but getting a line that is genuinely normal to the curve at a chosen point — and knowing where along the curve you are — is fiddly. The job comes up constantly in road and drainage work, where the alignment is a spline and … [Read more...] about SPER LISP: Draw Lines Perpendicular to a Spline in AutoCAD

Name: PasteAsBlock Description: A routine that allows you to choose a basepoint of a group of entities that you would like as a block, select the entities and select the insertion point that you want. NOTE: this lisp erases the original entities. Type: AutoCAD AutoLISP Routine Author: M.

PTEXT places text along a polyline path. Draw the route you want the lettering to follow — a curve, a series of straight runs, whatever the drawing needs — and the text is set out along it rather than sitting on a single straight baseline. It is by Viji Varghese of Kerala, India, dated March 1999. A path is more flexible than an arc Worth comparing with the arc … [Read more...] about PTEXT LISP: Place Text Along a Polyline Path in AutoCAD

NOTE puts a dialog box on screen with a list of standard notes in it. You pick one, then pick two points, and the note lands on the end of a leader pointing where you want it. It is by Ken Jolly, dated 1997, and it comes with a DCL dialog file. That last detail decides most of what follows. The list is one stone shop's, from 1997 Thirty-five notes are hard-coded into the … [Read more...] about NOTE LISP: Pick a Standard Note and Place It on a Leader
