Install & the plugin not loading

Works with: AutoCAD 2026 and AutoCAD 2027 on Windows. The same installer covers both.

Installing the plugin

The plugin ships as a single signed installer: AutoCADDTPlugin-Setup-<version>.exe.

1. Close AutoCAD.
2. Download the latest installer (your team lead or the in-AutoCAD update prompt will give you the link — it comes from the JobEngine site, not from GitHub directly).
3. Run the installer. No admin rights are needed — it installs per-user, so you will not see a Windows UAC prompt. The installer is code-signed.
4. Optional checkboxes on the way through (under "AI assistant integration"):
   • Set up Claude Desktop / Claude Code integration (stdio MCP) — on by default; adds the plugin's drawing-tools server to your Claude apps' configuration (details). Untick it if you don't use those apps.
   • Install the Claude Code guide skill — installs a helper guide for Claude Code into ~\.claude\skills\; only relevant alongside the integration above.
   • Open the AI Assistant & MCP guide when setup finishes (you can always come back here with DT_HELP).
5. Start AutoCAD. You should see the JobEngine ribbon tab and a [AutoCAD DT Plugin v...] loading message in the command line.

Where the plugin lives

Everything installs under your user profile:

You never need to touch these files in normal use, but support may ask you for the log files.

Support bundles: what to send us

When something goes wrong, send support:

1. The event log files from %APPDATA%\Autodesk\ApplicationPlugins\AutoCADDTPlugin.bundle\logs\ (one file per day; send the day the problem happened, plus the day before if it spans midnight).
2. The exact text of any [LOAD_DT] / [LLMCHAT] / other plugin messages from the AutoCAD command line (press F2 to open the text window and copy from there).
3. Your plugin version (shown in the loading message at startup) and your AutoCAD version (2026 or 2027).

Never send token.dat — it's your sign-in credential.

By default the plugin logs locally and to JobEngine's servers, so the local files are complete. If your config.json has "verboseLogging": false, local files are intentionally incomplete — mention that to support.

The plugin doesn't load at all

Symptom: AutoCAD starts normally, but there's no JobEngine ribbon tab, no [AutoCAD DT Plugin v...] loading message, and every plugin command (LOAD_DT, DT_PANEL, …) returns Unknown command.

Most likely cause: AutoCAD's security setting (SECURELOAD) is blocking the plugin because its folder isn't in AutoCAD's trusted-locations list — AutoCAD skips it silently, with no warning. (This has mainly been seen with unsigned development builds; a standard signed install usually isn't affected — if you installed from the official Setup.exe and still hit this, mention that to support.)

Fix:

1. At the AutoCAD command line, type TRUSTEDPATHS and press Enter.
2. When prompted for a new value, enter (keep any existing value, separated by ;): C:\Users\<your-username>\AppData\Roaming\Autodesk\ApplicationPlugins\... The trailing \... matters — it trusts subfolders too, and the plugin's files live two levels down inside the .bundle folder. (Equivalent UI route: OPTIONS → Files tab → Trusted Locations → Add, then browse to that folder and confirm when asked about subfolders.)
3. Restart AutoCAD. The setting is saved to your profile, so this is one-time.
4. If it still doesn't load, re-run the latest Setup.exe (with AutoCAD closed) and restart — then contact support with your log folder (it will likely be empty for the affected day, which is itself useful evidence).

Do not set SECURELOAD to 0 — that disables plugin security for everything, not just this plugin.

One specific command says "Unknown command" but others work

Cause: Your installed plugin version predates that command — commands are added in new releases.

Fix: Check your plugin version (the [AutoCAD DT Plugin v...] startup message) against the latest release, update, and retry. If you're already current and the command is documented for your version, report it to support with the command name and your log files.
