Are there any tutorials available on how to create custom connections? The macros are great but they don't fit every condition.
In theory there is , but there is no documentation. From version 2011 we have an open API (search for structural detailing comparison matrix).
In my original question I was not asking about how to create custom macro's (although that would be really cool). I was looking for info on how to manually create connection element manually. How to you make web stiffeners, add bolts and holes, cope a beam at a skewed connection etc.?
It is easy. Just use commands plate, drilling, welding and coping. If you have done one - you can copy it around.
Adpot drills is mostly used then.
