Hello,
it would be nice, when there would be a way to identify the start and the end of a beam. Best way, in my opinion, would be, to colorize the grips with an explicit color (like in thekla)

This Information would be helpful for different other commands - for example "copy with adjustment" or building hand-railings (if I start the hand-railing on the wrong end, there could be problems with the bolt-directions)

Kind regards
