SS – A Better Select Similar (Free AutoCAD LISP)

11th August 2026

FREE AUTOCAD LISP

SS — Select Similar, the way it should have worked

Like AutoCAD’s SELECTSIMILAR, but sharper: SS filters by object type, layer, colour and linetype together, works only inside the area you specify instead of the whole drawing, and — the killer feature — runs transparently in the middle of another command: type ’ss while ERASE or COPY is asking for objects.

It’s a family: SSL selects by layer only, SST matches the same text string, SSD grabs dimensions, SSB grabs blocks.

SS free AutoCAD LISP - an improved select similar with transparent use

How to use it

  1. Unzip, then load the .lsp with APPLOAD.
  2. Type SS (or ‘ss transparently inside another command).
  3. Pick the source object, then window the area to search.

Good to know

Filters Object type + layer + colour + linetype (SS); layer only (SSL); same text (SST); dimensions (SSD); blocks (SSB)
Transparent Yes – ‘ss works during ERASE, MOVE, COPY and friends
Scope The area you window, never the whole drawing
Commands SS, SSL, SST, SSD, SSB
