Tools, Plugins & LISP Routines for AutoCAD
CAD Exchange hosts AutoCAD plugins and LISP routines in two main flavours: AutoLISP/Visual LISP routines (.lsp, .fas, .vlx) loaded with APPLOAD, and managed .NET plugins (.dll) loaded with NETLOAD. Browse by category below — LISP routines for everyday automation, .NET plugins for ribbon-integrated workflows.
What makes a great tools, plugins & lisp routines for autocad
A great AutoCAD plugin loads cleanly into Trusted Locations, supports the AutoCAD versions you actually run (most pros need 2022-2026), documents every command it adds, ships with sample drawings, and explains exactly which system variables or AutoCAD settings it touches. Bonus points for an uninstall path and a clear undo strategy.
Common AutoCAD command prefixes used by listed plugins
- CADEX* — CAD Exchange community plugins
- BB* — block-and-batch utilities (rename, attribute edit)
- LM* — Lee Mac-style helpers (popular naming convention)
- LT* — layer-and-text routines

Frequently asked questions
What kinds of AutoCAD automation can I find here?
AutoLISP routines, Visual LISP applications (.fas/.vlx), .NET plugins (C#/VB.NET DLLs), VBA macros (.dvb), and AutoCAD bundles (.bundle) for one-click install. Filter by file type on the marketplace to narrow down.
Will plugins work in AutoCAD LT?
Generally no. AutoCAD LT does not host LISP, .NET, or ARX. The vast majority of CAD-automation plugins require full AutoCAD or a vertical (Civil 3D, MEP, Architecture, Plant 3D).
How do I install an AutoCAD plugin from CAD Exchange?
For LISP, use APPLOAD or our /guides/how-to-load-a-lisp-routine-in-autocad walkthrough. For .NET plugins, use NETLOAD — see /guides/how-to-netload-a-dotnet-plugin. For .bundle packages, just drop into %APPDATA%\Autodesk\ApplicationPlugins\.
Are AutoCAD plugins version-locked?
.NET plugins almost always are — they reference AcDbMgd/AcMgd for a specific AutoCAD release. AutoLISP is largely cross-version. Each listing here states the supported AutoCAD versions.
How does CAD Exchange protect me from malicious code?
Every uploaded .lsp/.dll/.exe runs through automated security scanning: code analysis, .NET decompilation, VBA extraction, and Dynamo parsing all feed into a risk score reviewed before listing approval.
Do plugins include source code?
Depends on the license type. 'Source Included' listings ship the .lsp source or the .NET project; otherwise you get the compiled binary only. Look for the license badge on each product card.
Can I get a refund if it doesn't work?
Yes — every paid plugin has a 7-day refund window if it doesn't load or doesn't do what's advertised. Refund requests go through the seller first, with admin arbitration if needed.
