Revit C# .NET API add-in to export Revit wall parts to DXF or SAT for CNC fabrication.

This add-in demonstrates various useful aspects along the way, such as:

• Implement the external application
• Create ribbon panel and command push buttons
• Load icons from assembly resources
• Select wall parts and handle optional pre-selection
• Export wall part elements to DWF or SAT
• Manage, create and populate shared parameter values

For more information, please refer to The Building Coder and the 12-minute Revit to CNC Direct YouTube video.

Detailed articles describing various implementation aspects include:

• Export Wall Parts Individually to DXF
• ExportCncFab on GitHub
• Driving CNC Fabrication and Shared Parameters
• CNC Direct – Export Wall Parts to DXF and SAT
• Migration to Revit 2018
• ExportCncFab SortMark Update

William Spier demonstrates running ExportCncFab in his 12-minute Revit to CNC Direct YouTube recording.
