From the developer:
SI Tools for Revit Structure is a Revit Structure add-in that provides advanced selection capabilities for structural members. Use the ribbon panel buttons to quickly select all beams, columns, or walls on a single level or in the entire model, regardless of type or material. Or use the Advanced Selection options to select a custom combination of beams, columns and walls.
Want to identify all 8X10 members, both beams and columns?
