Architecture

• Standard Inventor add-in wired up via .addin manifest and StandardAddInServer
• Dockable UserInterfaceManager panel backed by MVVM ViewModels
• Attribute tree built by walking AttributeSets on all owned objects of the active document

Building

1. Clone and open in Visual Studio
2. Run the correct Inventor Version according to your installed version
3. Build — BuildScript.cmd copies outputs to the Inventor add-in folder automatically

Design and Make marketplace bundle

For the Design and Make marketplace the add-in ships as a registry-free ApplicationPlugins bundle (not the dev BuildScript.cmd deploy). Create it with:

dotnet build ExtrabbitCode.Attributes\ExtrabbitCode.Attributes.csproj -c Release -p:Platform=x64 -p:CreateBundle=true -p:DeployToInventor=false

This produces, under ExtrabbitCode.Attributes\bin\Bundle\:

• stage\ExtrabbitCode.Attributes.bundle\ — PackageContents.xml + Contents\ (the add-in, its dependencies, and a relative-path .addin)
• ExtrabbitCode.Attributes.bundle.zip — upload this to the Design and Make marketplace

To smoke-test before submitting, copy the .bundle folder into %ProgramData%\Autodesk\ApplicationPlugins\ and start Inventor. The bundle manifests live in ExtrabbitCode.Attributes\Addin\Bundle\; the __VERSION__ placeholders in PackageContents.xml are filled from AppVersion in Directory.Build.props at build time. The release steps are listed in AGENTS.md.
