A resource dll is required to make .NET Connections available in Revit.
Each custom connection used in Revit requires two image files:
- Image - a 25x25 pixel image file that is displayed alongside the connection name in the list of available connections.
- Preview Image - a larger image displaying a preview of the connection in the Properties pane when adding new connections.
These images should be placed in a .NET dll as part of an embedded resource. The dll will be referenced in the
SteelConnectionsData.xml.
