I would love an option to assign a 'fixed' rebar number to any reinforcement i need. The "fixed" rebar number should not be changed by any rebar renumbering (like in Tekla Structures). It would be a lot easier to track identical stirrups and links across an entire project.
Also, an option to renumber all rebars globally and automatically assign new numbers to new rebars would be good. Renumbering should be done by partition number in an order chosen by the user, and subsequent partition should inherit the last rebar number from the previous partition.
You if can number rebars, why can't we number partitions as well?
