AutoCAD 2026 WebView2 Add‑In

A simple AutoCAD 2026 add‑in that embeds a WebView2 browser window directly within AutoCAD—no more switching between tabs!

---

Features

• Adds a new hehe panel under the Add‑ins ribbon tab in AutoCAD 2026.
• Click Open WebView to launch a modeless browser window docked on top.
• Keeps the window always in front (TopMost) so you can browse without losing focus in AutoCAD.

2. .NET 8.0 SDK installed

3. Microsoft Edge WebView2 Runtime (Evergreen) installed

Troubleshooting

• If you see unable to load WebView2Loader.dll, ensure:

  • The Edge WebView2 runtime is installed.
  • WebView2Loader.dll is copied to your output folder (set Copy to Output Directory = Always).

• If the Add‑ins tab is missing, run:

  NETLOAD "...\hehe_autocad_addin.dll"
  RESTART
  

• Make sure you target x64 in your project settings to match AutoCAD’s process.
