Known Limitations

Visualization Is Revit-Only

The visualization module (DirectContext3D) is a Revit-specific rendering API. AutoCAD-family hosts do not have an equivalent transient rendering path in RevitDevTool.

AutoCAD Host

• Command Browser is not yet available for AutoCAD
• Type stubs for AutoCAD API have not been generated

Python Runtime

Python execution depends on local machine state:

• Pixi is the primary dependency resolver — requires %APPDATA%\RevitDevTool\pixi-env to be writable
• If Pixi is blocked (enterprise policy restricting third-party executables), RevitDevTool falls back to pyRevit's bundled CPython (python.exe) if pyRevit is installed
• If neither Pixi nor pyRevit is available, the entire Python execution pipeline is unavailable — contact your IT department to whitelist one of these runtimes
• Package indexes (conda-forge, PyPI) must be reachable from the machine
• Python debugging requires debugpy and an available debug port
