The Advance Steel numbering tool automatically numbers single parts and assemblies for the entire model. The numbering procedure is a single button function and works on the entire model or on selected elements to find identical parts that should share the same number.
All beams and plates obtain a single part mark. All the other elements classify as attached parts. The numbering for single parts and assembly parts can be done for both in one step or separately.
You number elements with the tools located on the
Output tab 
Part marks panel.
