RECDIMS – Count Rectangles by Size into a Table (Free AutoCAD LISP)

11th August 2026

FREE AUTOCAD LISP

RECDIMS — count your rectangles by size, straight into a table

Select your rectangles and RECDIMS counts them by dimension — and by colour — then inserts a table with every size and its count, arranged largest to smallest. Columns for a BOM from a construction sketch, panels for a price quote, or a quick check of what sheet size a 1:1 drawing needs.

The table follows your current TABLESTYLE and text style, annotative included.
