If you draft mostly in 2D, AutoCAD LT will almost certainly do everything you need, and the AutoCAD LT cost is roughly a quarter of full AutoCAD. The two products share the same drawing engine, the same DWG file format, and the same core 2D drafting and documentation tools. The price gap exists almost entirely because full AutoCAD adds 3D modelling, programmatic automation, and the specialized industry toolsets. So the real question is not "which is better", it is "do I actually use the things LT removes?" For most architects and many drafters, the honest answer is no.
AutoCAD LT cost vs full AutoCAD: the numbers
Pricing shifts a little each release and by region, so always confirm on Autodesk's own buy page before you commit. As of mid-2026, the figures look roughly like this in USD:
- AutoCAD LT, about $60–65/month, roughly $440–520/year, or around $1,310–1,545 for a 3-year term.
- Full AutoCAD, roughly $260/month, in the region of $1,950–2,050/year, or about $7,800 for 3 years.
That makes full AutoCAD close to 4x the annual price of LT. Both are subscription-only now, there is no perpetual buy-once license from Autodesk for either edition. The monthly plan is the most expensive per-month and only worth it for short, defined projects; the annual term is the sane default if you draft year-round.
What you actually get for the extra money
Full AutoCAD is LT plus several capabilities LT does not include:
- 3D modelling, solid, surface, and mesh modelling, plus 3D visualisation and rendering. LT is 2D-only.
- Automation, AutoLISP, the API, and the ability to run and write scripts/add-ons. If your office relies on custom routines or third-party plugins, you need full.
- Specialized toolsets, Architecture, Mechanical, Electrical, MEP, Map 3D, Plant 3D, and Raster Design. These bundle object styles and libraries that can save serious time in their disciplines.
If none of those words describe your week, you are paying ~4x for features you will not open.
Who needs full AutoCAD
- You build or edit 3D models in AutoCAD (not just receiving 3D from Revit/ArchiCAD).
- Your team writes or runs LISP routines, scripts, or plugins to automate drafting.
- You live inside a discipline toolset, e.g. Plant 3D for piping, Electrical for schematics, Map 3D for GIS work.
Who is fine on AutoCAD LT
- 2D plans, sections, elevations, details, and construction documentation.
- Reading, marking up, and editing DWGs from consultants.
- Sheet sets, layouts, dimensioning, annotation, and printing/plotting to PDF.
In our own studio in Vilnius, the honest split is that most day-to-day 2D production sits comfortably on LT, and we reserve full seats for the people who actually model in 3D or maintain automation. Buying full "just in case" is the most common way teams overspend on CAD.
Who needs neither
This is the part most comparisons skip. If your job is mostly reviewing, marking up, measuring, and sharing finished drawings, rather than authoring DWG geometry, you may not need an AutoCAD seat at all. Reviewers, project managers, site teams, and clients usually work from exported PDFs. Paying for a CAD authoring license so someone can redline a sheet is overkill. A capable PDF tool is the right answer there, and it is a fraction of the cost.
A simple way to decide
- Do you author 3D, write automation, or live in a discipline toolset? → Full AutoCAD.
- Do you author 2D DWGs but none of the above? → AutoCAD LT.
- Do you mainly review, mark up, and share exported drawings? → Neither, a PDF workflow.
Mix and match across the team. There is no rule that everyone needs the same edition, and Autodesk lets you hold different seats under one account.
FAQ
Can AutoCAD LT open files made in full AutoCAD?
Yes. They share the same DWG format, so LT opens and edits drawings created in full AutoCAD. You just cannot edit 3D solids or run custom automation in LT, 2D geometry and annotation come across normally.
Is there a one-time purchase option for either edition?
No. Autodesk sells both AutoCAD and AutoCAD LT as subscriptions only (monthly, annual, or multi-year). Older perpetual licenses still run but are no longer sold or updated.
Is AutoCAD LT available on Mac?
Yes, AutoCAD LT and full AutoCAD both have Mac versions, though the Mac builds historically trail the Windows feature set. Confirm the current feature parity for your release on Autodesk's compare page before buying.
Bottom line: pick the cheapest edition that covers what you actually do, and re-check the live pricing on Autodesk before you sign. And for the heavy, recurring work of opening, marking up, and sharing large 50–200 MB+ CAD exports, where you do not need an AutoCAD authoring seat at all, a fast local PDF editor like Ncored handles it smoothly offline, with a free 14-day trial at ncored.com.
