Several long-standing archival communities attempt to preserve old software. While not officially sanctioned by Autodesk, these sources are often "verified" by user community checksums.

Crucial Step for Any Downloaded File: Before installing, right-click the .exe or .iso and upload the file to VirusTotal.com. This scans it with 60+ antivirus engines. If any flag it as "HackTool" or "Keygen," you are risking your network.
Autodesk Mechanical Desktop (ADT) 2009 is a discontinued 3D mechanical-design and drafting application that extended AutoCAD with parametric modeling, assemblies, and integrated 2D/3D workflows. Released in the mid-2000s, ADT merged solid modeling and associative drawing generation to support mechanical engineering workflows. Autodesk ended active development and support for Mechanical Desktop years ago, and its core capabilities were succeeded by Autodesk Inventor and enhanced AutoCAD toolsets.

Autodesk Mechanical Desktop (MDT) 2009 was the final release of this once-popular mechanical CAD software before it was discontinued by Autodesk. Today, it is primarily used by engineers to migrate legacy data into modern systems like Autodesk Inventor. Availability and "Verified" Downloads
Because this software reached its end-of-life years ago, obtaining a "verified" download is difficult:
Official Downloads: Autodesk no longer provides direct public downloads for MDT 2009. Historically, it was available as a supplement for Inventor 2009–2012 users through a special installer provided by Autodesk support.
Licensing Barrier: Autodesk ceased re-authorizing 2010 and older software in August 2019. Even with a valid original serial number, you likely cannot activate the software online today.
Current Solution: If you need to access MDT files, the official recommendation is to use Inventor 2018 (the last version to unofficially support the MDT translator) to import and migrate files to a modern format. Core Features of MDT 2009
As the final iteration, MDT 2009 combined classic AutoCAD drafting with advanced 3D mechanical design tools:
Hybrid Modeling: Supported wireframe, surface, and solid modeling within a single environment.
Parametric Design: Allowed for dimension-driven changes, where updating a value automatically adjusted the geometry.
Standard Parts Library: Included a vast database of pre-built mechanical components (bolts, bearings, etc.) to speed up assembly design.
DWG Native: Full compatibility with the AutoCAD DWG format, ensuring easy sharing with other CAD users at the time.
64-Bit Support: MDT 2009 was the first (and only) version to offer a native 64-bit version, significantly improving performance for large assemblies. Technical Requirements
MDT 2009 was designed for older hardware and operating systems: OS: Windows XP (SP2) or Windows Vista (32-bit or 64-bit). CPU: Intel Pentium 4 or AMD Athlon (2.2 GHz or higher). RAM: 1 GB minimum (2 GB recommended for Vista or 3D work).
Graphics: 1280 x 1024 resolution with 128 MB video RAM and OpenGL or Direct3D support. Alternatives for Legacy Data
If you are trying to open old MDT files, consider these more accessible options:
Autodesk Inventor: Can often import MDT files directly if a compatible version (like 2018) is used.
AutoCAD Mechanical: While it lacks some of MDT's 3D parametric depth, it handles 2D mechanical drafting and standard parts in a modern environment. Autodesk® Mechanical Desktop® 2009 Release Readme
Autodesk Mechanical Desktop (MDT) 2009 was the final release of the product before it was discontinued. While official support has ended, it remains available through specific legacy channels primarily for users needing to migrate data to modern platforms like Autodesk Inventor. Official Download & Availability
There are no longer "live" public download links on the main Autodesk storefront, but legacy installers are provided for specific migration workflows:
For Inventor Users: Autodesk has historically provided MDT 2009 installers to help users migrate legacy .dwg files into Inventor formats.
Update Files: Official service packs, such as Mechanical Desktop 2009 SP3, are still documented for stability and bug fixes.
Account Access: If you previously owned a license, you may find downloads under the "Previous Versions" section of your Autodesk Account. Licensing & Activation Status
Legacy Activation Ceased: Since 2019, Autodesk has largely stopped issuing new activation codes for versions 2010 and older.
Subscription Rights: Active subscribers may have "Previous Version Rights," but these typically only extend back a few years, not to 2009.
Perpetual Licenses: If you have a perpetual license and a serial number, you can still use the software, but reactivating it on a new computer after a crash may require contacting Autodesk Support directly. System Compatibility
