What of DraftSight do you currently license?

that can be run directly from a USB flash drive without standard local installation. Developed by Dassault Systèmes , DraftSight is an industry-leading, proprietary 2D and 3D CAD application natively built for local installation on Windows and macOS.

If your workflow strictly requires a lightweight CAD program that runs directly from a USB stick without installation, consider legitimate open-source alternatives: DraftSight Downloads

Historically, DraftSight gained popularity as a high-quality free 2D CAD tool. However, it transitioned to a paid-only subscription model in 2019 to better support its professional toolset and frequent updates .

Interestingly, Dassault Systèmes has addressed the mobility need through an official channel: 3DEXPERIENCE DraftSight, a cloud-connected version accessible from any device with an internet connection.

| Software | Portable? | License | Notes | |----------|-----------|---------|-------| | | Yes (unofficial portable on PortableApps.com) | GPL (free) | 2D only, DWG support limited | | QCAD | Yes (official portable version available) | Free trial / paid ($39+) | Good 2D CAD, uses its own format + DXF | | NanoCAD | No (but lightweight installer) | Free (basic) / paid | Good DWG compatibility, Windows only | | DraftSight (free version) | No (requires install) | Free for personal / non-commercial | Must install normally |

In 2013, another user reported that while DraftSight appeared to be inherently portable, making it work required some technical effort: "I found that the package is portable. However, the .exe file is 3 layers deep. Not sure how to make it portable". This indicates that while DraftSight might be "portable-friendly" in theory, creating a fully functional portable version involves overcoming several technical hurdles.

CAD programs are highly complex engines that rely heavily on specific C++ redistributables, .NET Frameworks, and direct access to graphics hardware drivers. Unofficial portable packages strip away standard system dependencies. As a result, you are likely to experience frequent crashes, rendering glitches, and—worst of all—corrupted .dwg or .dxf project drawings that can wipe out hours of professional work.
