AutoLISP Routines

CIVILINE draws a boundary line from a distance and a bearing you type, then labels it with both. It is the everyday task of putting a title boundary onto a drawing from the figures on a survey plan, done as one command instead of a line, a rotation and two pieces of text. The provenance is the nicest of anything in this library. It was written in January 1992 at Billings … [Read more...] about CIVILINE LISP: Draw and Label a Boundary from Bearing

It is the fix for a drawing where every symbol comes in red no matter what layer it lands on. Sensibly, it skips xrefs and xref-dependent blocks. Those belong to another drawing and editing their … [Read more...] about Block to BYLAYER LISP: Reset Block Colours in AutoCAD

It was written in the DOS era of AutoCAD and shipped with batch files and a script so the same rename … [Read more...] about Block Rename LISP Routine for AutoCAD (Auto Block Rename)

BLKRPT counts how many times each block is inserted in your drawing and produces a report.

It is by Jon Shapiro, version 2.0, dated 27 January 1991 — and it announces itself when it loads, which is a courtesy worth … [Read more...] about BLKRPT LISP: Block Count Report for AutoCAD Drawings

Block Count is a compact AutoLISP routine that tallies how many times each of your chosen blocks appears in the current drawing, then writes the totals out to a plain text file.
