Why we give these away

Docuex is a UK CAD conversion company. We live inside AutoCAD all day, and over the years we've built dozens of small LISP utilities to scratch our own itches. We've polished the best of them and released them free because, frankly, most of the free LISP available online is bug-ridden, undocumented or stuck on AutoCAD versions from a decade ago. We thought we could do better.

No paywall, no email gate (the form is optional). If a tool saves you ten minutes, that's win enough for us. If you ever need a custom LISP built for your workflow, that's where we charge, see below.

How to install

One file does it all.
  1. Extract the downloaded zip to a stable folder (e.g. C:\Docuex\LISP\).
  2. In AutoCAD, type APPLOAD, browse to that folder and load docuex-tools.lsp.
  3. Tick "Add to Startup Suite" so the tools load every time AutoCAD starts.
  4. Type DX-HELP at any time to see the full command list inside AutoCAD.

All 14 commands, at a glance

All commands are prefixed DX- to avoid collisions with your existing macros. Type DX-HELP inside AutoCAD for the reference any time.

LT column: ✓ = works in AutoCAD LT, blank = needs full AutoCAD (Visual LISP / ActiveX), "partial" = works for some entity types only.

Need a custom LISP built?

If the free tools save you time but you've got a workflow they don't quite cover, we build bespoke LISP utilities for clients, automated layer cleanups, project-specific block managers, batch operations across hundreds of drawings, custom DWG/DXF export pipelines. Tell us what you do every day that bores you, and we'll quote it as a fixed-price job.

Frequently asked

Are these really free?

Yes. No sign-up, no payment, no watermark, no daily limit. Use them as much as you like, on as many computers as you like. We ask only that you don't rebrand or resell them, see the licence inside the download.

Does it work with AutoCAD LT?

Most tools do. The exceptions are DX-FLIPREADABLE, DX-CHECKOVERLAP, DX-MOVE2CENTRE (MTEXT support), and DX-BW / DX-BWSEL, these use Visual LISP / ActiveX, which AutoCAD LT does not run. Everything else (text case, rotation, rounding, sums, explode, hatch, attribute export, room data) works fine in LT.

What AutoCAD versions are supported?

AutoCAD 2018 and later. Earlier versions may work but we don't test against them.

Do you collect my email?

Only if you give it to us via the form, in which case we use it once to email the download link and we may occasionally let you know about a meaningful update or bug fix to the tools. You can unsubscribe any time. If you don't want to share your email, the direct download link works without one.

Can I redistribute or modify the tools?

You can modify them freely for your own internal use. You may not redistribute or resell them, in either original or modified form. We want a single canonical download location so that bug fixes reach everyone. Full terms in the LICENCE.txt inside the zip.

Will you keep adding tools?

Probably, yes. Bug fixes within version 1.x will be free and delivered via email if you opted in. Major new tools may or may not be added to this free pack depending on what makes sense.

I want a custom LISP for my company's workflow. How does that work?

Email us at info@docuex.co.uk with a short description of what you'd like automated. We'll usually reply within a day with clarifying questions and, once we understand the scope, a fixed-price quote. Typical custom utility jobs are £200-£800 depending on complexity. The result is yours to use, modify and keep as long as you like.

Found a bug, what do I do?

Email info@docuex.co.uk with the command name, a description of what happened, and ideally the AutoCAD version you're on. We don't promise a fixed response time on free tools but we usually address real bugs within a few days.
