Predefined material grades, bolt assemblies, and rebar specific to local building codes.

A library of regional steel and concrete shapes (e.g., AISC sections for the US or European sections).

Sub-configurations (like "Steel Detailer" or "Bridge Designer") that simplify the interface by showing only relevant tools. How to Install and Manage Environments
