If subsequent additions or deletions are made to the model, the member numbering is not automatically updated. New members are assigned the next higher available number regardless of their location, old members retain their numbers, and deleted member numbers are no longer used. If desired, the Options - Renumber Members command can be invoked at any time; otherwise the old numbering assignments will always be retained.

Each layout type has its own set of numbers. For example, there is a column number 1 on every level.

Each element type has its own set of numbers. For example, there is a column number 1 and a beam number 1 on the same level.

Member numbers can be viewed by invoking the appropriate Show Numbers command from the Options menu or by clicking the desired Show Numbers button on the toolbar.

Member numbers are used throughout the RAM Structural System to identify members, especially the output reports.
