Opening the model up it is almost impossible to determine where this came from it looks a little like an IFC export into Revit but again impossible to determine so i would highly suggest it was not done in Revit directly.

The steel section references are not familiar with standard Revit Section Library Families but you can select them and get the dimensions and create your own custom section based of this but delving further it may get more complex.
As regards the connections you could review the Revit Library for predetermining the connections at hand and then all ways use Custom elements where required. Or if needed simply use the Steel Tab Tools to create them all from scratch.


If these frames are what you do, really this would be better achieved in Advanced Steel as there is more flexibility and range of tools available and if you are manufacturing the frames creating manufacturing drawings and integration with CNC machining and automation for fabrication is achievable directly from Advanced Steel, alternatively the team behind Advance Steel have a Revit Addin for connection and may be work a look or a chat with them to see what is best for your needs.
