Automatically create structural steel connections in Revit using Dynamo.
Before you start working with steel connections for Dynamo in Revit, review the following:
Install the Autodesk Steel Connections package.
Only connections available in Revit are supported.
Non-standard steel shapes (generally families created by the user) are currently not supported.
Embedded steel and concrete connections are currently not supported.
Nested connections - two different connections in the same node, on the same elements are currently not supported.
Connections that require an input other than framing elements are currently not supported.

Connections that require the system axes of the framing element to be farther than the hardcoded tolerance cannot be placed.

You cannot currently override the connection parameters from the connection type properties.
You cannot select multiple values for filtering by the framing element section or shape.
You cannot stop a script once it has started executing.
When you filter by internal forces, only the force/moment value at the end of the framing element is considered.
