The 2021 version introduced a "download once, license many" model where the base platform could be extended via five specialized modules:

: Provides native support for DWG formats and improves the expertise of IFC models for BIM workflows. External Blocks

: Can be carried on a flash drive and used on different workstations (e.g., moving from an office desktop to a field laptop).

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.

It supports versions from R11 to DWG 2018, ensuring no data loss when sharing files with AutoCAD users.

Unlike traditional software that writes registry entries and creates folders in Program Files and AppData , the portable version stores all settings, configurations, and temporary files directly on the removable drive.
