The 64-bit architecture allows the software to utilize significantly more Random Access Memory (RAM) than its 32-bit predecessors. In the context of BIM, where models can easily grow to contain thousands of steel members, rebar groups, and complex geometry, memory management is paramount.

An engineer uses the 2020 suite to model 20 floors of composite steel decking. Using the memory handling, they import point clouds from laser scans to verify existing conditions. The suite automates column layout and generates rebar shop tickets for the foundation mat.

The "Design Suite" nature of this 2020 release means it is not just a single piece of software but an integrated ecosystem:

This article takes an in-depth look at the 2020 release of the Design Suite, specifically optimized for the 64-bit (x64) architecture, exploring its features, system requirements, and why it remains a pivotal tool for engineers and detailers even years after its release.
