The existing connection macros will work for the most common connections but they might not work for non-standard situations.
For such situations, you can manually create the connection by creating plates, bolts, welds & cuts. Trimming, chamfering & cutting whole or part of the connecting members may also be required.
Manual connection will not have any design or checks - it is purely for drawing production purposes.
Please refer to these on how to deal with with manual connections, detailing & macros :
