Autodesk stopped selling most of its big-name apps on their own years ago. Today, if you want Revit, Civil 3D, or Inventor, you usually buy them inside an industry Collection — a bundle of tools built around one workflow. The two that cause the most confusion are the AEC Collection and the PDMC Collection. They cost the same, they both include AutoCAD, and their names are alphabet soup, so it is easy to grab the wrong one and end up paying for software you will never open.
This guide clears it up in plain English. We will cover exactly what each bundle includes, who each one is actually built for, how Commercial and Education pricing differ, and how to pick the right Collection the first time. No marketing spin — just the facts you need before you spend real money.
Short answer: Buy the AEC Collection if you design buildings or infrastructure (it is built around Revit and includes Civil 3D, InfraWorks, and Navisworks). Buy the PDMC Collection if you design منتج or machines (it is built around Inventor and includes Fusion, Nastran, and Vault). Both include AutoCAD, both cost the same, and both come in Commercial and much cheaper Education editions.
⭐ Key Takeaways
- AEC = Architecture, Engineering & Construction. It centers on Revit for BIM, buildings, and infrastructure.
- PDMC = المنتج Design & Manufacturing. It centers on Inventor for mechanical and product design.
- Both bundles include AutoCAD, so you never need to buy AutoCAD separately alongside either one.
- Your industry decides for you — the choice is almost never a close call once you know what you design.
- Education pricing is a fraction of Commercial pricing for eligible students and educators.
What’s in each collection
Both Collections are subscriptions that unlock a fixed set of desktop apps plus some cloud services. The overlap is small — really just AutoCAD and a couple of shared tools — and everything else is tuned to a different kind of work. Here are the headline apps side by side.
| Category | AEC Collection | PDMC Collection |
|---|---|---|
| Core / flagship app | Revit (BIM) | Inventor (mechanical CAD) |
| General 2D/3D drafting | AutoCAD | AutoCAD |
| Civil & site design | Civil 3D, InfraWorks | — |
| Coordination / review | Navisworks | — |
| المنتج / cloud CAD | — | Fusion (Fusion 360) |
| Simulation | Robot Structural Analysis | Nastran (FEA) |
| Data management | — | Vault |
| Factory / layout | — | Factory Design Utilities |
Autodesk adjusts the exact app list from time to time, and both Collections carry a few more specialist tools than we list here. But the pattern above is the important part: AEC is a building-and-site toolkit anchored by Revit, and PDMC is a product-and-manufacturing toolkit anchored by Inventor. AutoCAD sits in both because nearly every design discipline still needs solid 2D drafting.
Who the AEC Collection is for
AEC stands for Architecture, Engineering & Construction. If your drawings turn into something you can walk through or drive on, this is your Collection. It is the standard toolkit for:
- Architects and BIM teams who model buildings in Revit and coordinate structure, mechanical, electrical, and plumbing systems.
- Civil and infrastructure engineers designing roads, grading, drainage, and site plans in Civil 3D and InfraWorks.
- Structural engineers who need Revit plus analysis tools like Robot Structural Analysis.
- Construction and coordination managers who use Navisworks for clash detection, 4D scheduling, and model reviews.
The thread tying it together is BIM — building information modeling. Revit is the center of gravity, and the surrounding apps exist to design the site, analyze the structure, and coordinate the build. If the words “floor plan,” “alignment,” or “clash detection” describe your day, buy AEC.
Who the PDMC Collection is for
PDMC stands for المنتج Design & Manufacturing. If your drawings turn into a physical part, an assembly, or a production line, this is your Collection. It is built for:
- Mechanical engineers and product designers who model parts and assemblies in Inventor.
- Design teams that want cloud-based, all-in-one CAD/CAM with Fusion (Fusion 360).
- Simulation engineers running finite-element stress and structural analysis with Nastran.
- Manufacturing and tooling teams who need Vault for version control and Factory Design Utilities to lay out production floors.
Here the center of gravity is Inventor, backed by Fusion for modern cloud workflows and by simulation, data-management, and factory tools for getting a design into production. If you talk about “assemblies,” “tolerances,” “CAM,” or “BOMs,” buy PDMC.
Commercial vs Education pricing
Both Collections come in two very different price tiers, and the gap between them is enormous.
Commercial is the standard license for businesses, freelancers, and anyone using the software to make money. It is what most buyers need, and it is fully licensed for professional and commercial work.
Education is a heavily discounted license for eligible students and educators. It unlocks the same apps for learning and coursework at a fraction of the Commercial price. The trade-off is that Education licenses are intended for study, not for paid commercial projects — so if you are running a business, choose Commercial even though the Education price looks tempting.
Autodesk sells both tiers on a subscription basis, and you can pick the term that matches how long you will actually use the tools. SoftKeys offers each Collection in 1-month, 1-year, and 3-year terms — monthly is handy for a short project, while 1-year and 3-year lower your effective monthly cost the longer you commit.
Note: Education pricing requires eligibility (an active student or educator status). It is meant for learning and academic use, not commercial projects. If you plan to earn money with the software, buy the Commercial edition — it is the correct and fully compliant choice for professional work.
Which one to buy
You almost never need to agonize over this. Ask one question: what does my design become in the real world?
- A building, a bridge, a road, or a site? Buy the AEC Collection. Revit, Civil 3D, InfraWorks, and Navisworks are exactly what that work needs.
- A part, a machine, a consumer product, or a factory line? Buy the PDMC Collection. Inventor, Fusion, Nastran, and Vault are built for it.
- Only need AutoCAD? Then you may not need a Collection at all — a standalone AutoCAD license could be cheaper. Buy a Collection when you genuinely use two or more of its apps.
Because both bundles cost the same, price is not the tiebreaker — fit is. Buying the wrong Collection does not save you a cent, it just leaves you without the flagship app you actually need. After you know AEC vs PDMC, your only remaining decisions are Commercial vs Education (based on eligibility) and which subscription term matches your timeline.

Frequently Asked Questions
Do both Collections include AutoCAD?
Yes. AutoCAD is included in both the AEC Collection and the PDMC Collection, so you do not need to buy it separately alongside either bundle. That shared inclusion is one reason the two are easy to confuse.
What is the single biggest difference between AEC and PDMC?
The flagship app. AEC is built around Revit for buildings and infrastructure (BIM), while PDMC is built around Inventor for mechanical and product design. Everything else in each bundle supports that core workflow.
Can I buy both Collections?
Yes, if your work genuinely spans both worlds — for example, a firm that designs both buildings and manufactured منتج. But for most people, one Collection covers everything they do, so buying both is rarely necessary.
Is the Education edition the same software as Commercial?
It unlocks the same applications, but the Education license is intended for eligible students and educators for learning and coursework — not for paid commercial projects. If you are earning money with the software, choose the Commercial edition.
Which subscription term should I pick?
Choose based on how long you will use the tools. A 1-month term suits a short project or a trial run, while 1-year and 3-year terms lower your effective monthly cost the longer you commit. SoftKeys offers both Collections in all three terms.
I only need Revit or Inventor — should I still buy the Collection?
If you will use two or more apps from a bundle, the Collection is usually the better value. If you truly only need one app, a standalone license may cost less. Compare the single-app price against the Collection before deciding.
Final thoughts
The AEC vs PDMC decision looks intimidating because of the acronyms, but it comes down to one honest question: do you design buildings and infrastructure, or منتج and machines? Answer that and the right Collection is obvious — AEC with Revit for the built environment, PDMC with Inventor for manufacturing. Both cost the same, both include AutoCAD, and both come in Commercial and Education editions across flexible terms. Pick the bundle that matches your work, choose Commercial or Education based on your eligibility, and you will get every tool you need without paying for a shelf full of apps you will never open.
