Autodesk Autocad --env.acad Release Name- File
AutoCAD stores settings (support paths, printer configs) in named profiles within the registry. Launch with:
acad.exe /p "Release2024_Production"
This is cleaner than environment variables.
Autodesk releases a new version every March. The --env.acad syntax has been stable since AutoCAD 2010, but the release name changes. autodesk autocad --env.acad release name-
To future-proof your deployment:
Environment variables expanded via --env.acad are subject to AutoCAD’s internal string buffer limit (typically 256 characters for DRV paths). If your network path is long, AutoCAD will truncate it silently. Solution: Use short network shares (e.g., Z:\ instead of \\long-domain\shares\department\cad\). AutoCAD stores settings (support paths, printer configs) in
At the AutoCAD command line:
! (strcat "ACAD env: " (getenv "ACAD") "\nACADPREFIX: " (getenv "ACADPREFIX"))
Currently, AutoCAD separates the "Reference" workflow from the "Scripting" workflow. If a user opens a drawing via a script (using /b or --env.acad settings), references (XREFs) that are missing or need updating often trigger interactive dialogs or simply fail to load if the paths aren't identical to the last saved state. This is cleaner than environment variables
Source-Attach introduces a command-line parameter and API flag that forces AutoCAD to resolve XREF paths against a specific "Source Environment" variable before the drawing interface fully initializes. It allows a drawing to act like a dynamic template, re-linking its dependencies based on the environment it is launched in.
If your goal aligns with the spirit of --env.acad release name-—dynamically changing AutoCAD’s behavior per release—use these official methods instead.
The ACAD environment variable is a system- or user-level variable that stores a semicolon-separated list of folder paths. AutoCAD reads these paths during startup before reading the profile-specific support paths stored in the Windows Registry or the current workspace.
When deploying via SCCM or Intune, you can launch AutoCAD with a temporary override:
$env:ACAD_RELEASE = "2025"
Start-Process "C:\Program Files\Autodesk\AutoCAD 2025\acad.exe" -ArgumentList "--env.acad release name-"
