Understand potential constraints when working with custom steel connections.
- Only steel fabrication elements such as profiles, bolts, welds, plates and entire standard connections can be members of custom connections. Family-based elements (generic or other) cannot be added.
- Custom connections cannot contain only generic connections. A custom connection must contain at least one of the following elements: profile, bolt, weld, plate or standard connections.
- Custom connection types are not available in the Structural Connection Settings dialog and cannot be loaded/unloaded form the project using this dialog. Use the Project Browser to unload custom connection types.
- Sharing custom connection definitions between projects is not implemented. Use the Copy/Paste tools to share definitions of custom connections between projects.
- Custom connections cannot contain other custom connections.
- The custom connection names correspond to the family names in Revit. From this perspective, creating different Revit types is not available.
- Adding an object to a custom connection will remove all the elements (such as dimensions or tags) attached to the respective object.
- Only structural framing and column elements are valid input elements for custom connections.
- Custom connection types cannot be duplicated or renamed.
- Custom connections cannot contain elements controlled by other connections.
- Custom connections cannot contain elements that are in relation to elements other than the ones contained by the custom connection or its input elements.
- Custom connections can be created on up to 3 steel elements. These steel elements need to be
supported structural steel column and framing shapes and families for the steel fabrication workflow.
- If a connection type is used within a custom connection and it is not used outside of custom connections anywhere else in the model, this connection type will be displayed in the list of unused Structural Connection types from Purge Unused. If these types are purged, the custom connections using them will remain untouched, but their corresponding entries from Schedules will show a blank for Type and Family and Type parameters.
