Running CAD from a USB drive requires specific optimizations to ensure smooth performance.
To run the 2021/portable version effectively, the following specifications are generally recommended: Windows 10 or 11 (64-bit). Processor: 2.0 GHz minimum (3.0 GHz+ recommended). RAM: 4 GB minimum (16 GB for 3D modeling and point clouds). nanocad portable 2021

For most users, the smartest workflow is to install directly on your primary workstations and keep your project files on a USB drive. If you absolutely must have a portable CAD app, buy a legal copy of QCAD Portable or use LibreCAD Portable —both offer peace of mind that no third-party repacker can provide. RAM: 4 GB minimum (16 GB for 3D modeling and point clouds)
If running from a portable drive, the host computer must still meet these minimum specs: Windows 10/11 (64-bit recommended). Minimum 4GB (16GB recommended for 3D modeling). At least 7GB of free space on the host or external drive. 1GB VRAM with OpenGL 2.1 or DirectX 11 support.
Engineers can carry their configuration and specialized toolsets on a USB drive.
In the world of CAD, portability is often sacrificed for power. You either commit to a heavy, license-managed installation of AutoCAD, or you struggle with web-based viewers that choke on large files.
