CAD Exchange for CAD Drafters
CAD drafters use CAD Exchange for the everyday-automation that compresses production time: layer state managers, batch text editors, block insert/explode utilities, dimension cleanups, drawing audit helpers. Most listings here are built by working drafters who hit the same pain on real deliverables.
The pain points we hear
Layer drift across drawings
Twenty drawings, twenty subtly-different layer sets. Layer state save/restore plus bulk-rename LISP routines bring order back.
Text/MText cleanup
Find/replace across all text in a drawing, batch height changes, mtext-to-text conversion — vanilla AutoCAD makes this harder than it should be.
Block management
Insert with attribute defaults, batch update from an Excel source, explode-with-attributes-preserved. The block utilities on CAD Exchange cover most of the repetitive cases.
Drawing audit and cleanup
Pre-issue audits — purge plus, layer harmonization, scale checks, plot-style verification — go from hours to a single command with the right plugin.
What you get on CAD Exchange
- AutoLISP and Visual LISP routines for everyday drafting
- Compiled .fas/.vlx for fast load with source hidden
- Source-included listings when you need to adapt to your standards
- Verified compatibility with AutoCAD 2022 through 2026 plus the verticals
Frequently asked questions
I'm new to loading LISP — where do I start?
Read /guides/how-to-load-a-lisp-routine-in-autocad. It's a 3-minute setup; once you've loaded one routine, the rest is identical.
Will the routines I buy collide with each other?
Rarely. CAD Exchange listings document the command names they add — check the listing pages before installing two plugins from different sellers that might use the same command name.
Do these work in AutoCAD LT?
No. AutoCAD LT doesn't have LISP or .NET. Full AutoCAD or a vertical (Civil 3D, MEP, Architecture, Plant 3D) is required.
