LibreCAD is a free, open-source 2D CAD program. You can download a PortableApps.com version. It runs directly from a USB stick with no install. It cannot handle 3D or complex parametrics, but for simple floor plans or schematics in DWG format, it is perfect and 100% legal.

If you have a valid perpetual license for AutoCAD 2010 (purchased before Autodesk moved to subscription-only models), you could technically create a portable version using tools like VMware ThinApp or Turbo Studio (formerly Spoon Studio). The process involves:
However, even with a legal license, this violates Autodesk’s EULA, which explicitly prohibits repackaging, virtualizing, or redistributing their software. Autocad 2010 Portable
AutoCAD 2010 Portable represents a fantasy for many designers: professional CAD power on a cheap USB stick, usable anywhere without installation. In a perfect world, Autodesk would offer such a tool. But in reality:
If you still choose to hunt for an AutoCAD 2010 Portable download from an obscure forum, remember: If you are not paying for the product, your data becomes the product. The only safe portable CAD tool is one from an official source—and since Autodesk doesn't make one, your safest bet is to carry a lightweight laptop with the full installed version.
Design smart. Stay legal. And keep your USB drives for your files, not your software cracks. LibreCAD is a free, open-source 2D CAD program

The 2010 version had a specific issue with DWG file headers when run from a non-standard path (like D:). Portable hacks often bypass critical initialization routines, leading to: However, even with a legal license, this violates
| Promise | Reality | | :--- | :--- | | Run from a USB drive on any PC | Requires registry edits and temp files that leave traces behind | | Lightweight & fast | Still a 1GB+ suite; slow read/write speeds from USB 2.0 cripple performance | | No license cost | Pirated software = legal liability + no security updates | | Works offline | Often phones home to malicious command servers |
NanoCAD is a Russian-developed clone that mimics the classic AutoCAD interface (pre-ribbon style). The free version reads/writes DWG files back to version 11. It requires installation, but it is only 200MB—small enough to install quickly on any machine.
Because the software is "virtualized" (running in a sandbox without registry access), the portable version is often:
You don’t need to risk your entire system just to edit DWG files on the go. Here are three safe, legal, and genuinely portable options:
