51 production-ready AutoLISP commands for AutoCAD 2024–2027. Piping and isometrics, automatic dimensioning, text processing, batch PDF output and data export — built by a working plant designer, for working designers.
Buy a licence, download a ZIP, and unpack it wherever you keep your tools. Point AutoCAD at the folder, enter your key once with YLICKEY, and you are ready. No installer, no admin rights — about three minutes.
Every command comes from real drafting work — piping diagrams, plant layouts, structural details. 51 commands covering blocks, dimensions, text, layers, PDF output and material take-off.
Your license is verified online when you activate it, then re-checked only once every 7 days. Between checks YTOOLS runs completely offline, so a site PC with no connection keeps working.
Pay once, use forever. No subscription, no expiry. Each key activates on 2 machines, and you can move it to a new PC yourself with YLICCLR and YLICKEY.
Every plan is a one-time purchase in USD. Higher plans include everything below them. Piping Edition is the exception — it is a dedicated route for pipe and plant work: the 30 Standard tools plus the 10 piping-specific ones, so a piping drawing can be finished end to end. If you also need sheet-metal, survey and layer utilities, choose Professional.
Includes every Starter, Standard and Piping tool — all 51 commands.
Includes all 30 Standard tools — dimensions, text and output — so nothing is missing when you finish the drawing.
Includes all 15 Starter tools.
Includes YMENU, the launcher and toolbar for every YTOOLS command.

Extract the ZIP and put the YTOOLS folder on a local drive — C:\YTOOLS works well. Avoid OneDrive or Google Drive folders: AutoCAD cannot treat a synced folder as trusted.
In AutoCAD, OPTIONS → Files → add the fas subfolder to Trusted Locations and to the Support File Search Path.
APPLOAD → Startup Suite → add YTOOLS-LOAD.lsp from that same folder, then restart AutoCAD.
Type YLICKEY, paste the key from your purchase email, then type YMENU to open the toolbar.
Tested on AutoCAD 2024, 2026 and 2027 (Windows, Japanese and English editions). Not compatible with AutoCAD LT or BricsCAD.
14-day money-back guarantee, and a free 7-day trial of the full toolset before you pay anything.
Email support@comworks.design — we reply within 24–48 hours. Every purchase includes the current version permanently.
If you draw pipe or plant layouts, Piping Edition is the best value — it has the 30 general tools plus the 10 piping ones, so a piping drawing is finished end to end. If your work is mixed, or you need survey, sheet-metal and layer utilities as well, choose Professional.
Yes, and you never lose what you paid. Email us and we will send an upgrade code that deducts the full price of your current licence from the higher plan.
Two. Moving to a new PC is self-service: run YLICCLR on the old machine to release the activation, then YLICKEY on the new one.
No. The licence is checked when you activate it and then re-checked only once every 7 days. Between checks YTOOLS works fully offline.
No — the 7-day trial unlocks all 51 tools. When it ends, any command you are running finishes normally; you simply enter a purchased key to carry on.
The version you buy is yours permanently. Updates that add support for newer AutoCAD releases are offered as an optional annual renewal — you are never forced to pay to keep using what you bought.
