When dealing with a substantial number of members within a STAAD model, the design parameters tend to split automatically. Consequently, this automatic splitting poses challenges when attempting to review the design parameters. The same situation applies to member loading as well.
Thank you for posting this idea. It is currently a quirk of the GUI that when it has a large list assigned to a command, it attempts to optimise the commands to assist in the processing that the engine would need to undertake. However this may be an unnecessary step and will be investigated. If it makes sense, then the logic can be simplified and this optimisation routine removed to retain the commands as defined.
