Comosys 4.1

Comosys by Proya Software is an integrated 3D modeling and detailing platform for structural steel and reinforced concrete. Designed for fabricators, engineers, and detailers, it streamlines the workflow from modeling to shop-ready deliverables. Users can build constructible models; apply parametric connections, joints, and reinforcement; and automatically generate general arrangement drawings, assembly and single-part drawings, rebar schedules, material takeoffs, and fabrication data. A change-aware engine keeps drawings and reports synchronized with the model, reducing manual rework and errors.

Key capabilities:

• 3D modeling for steel and reinforced concrete, with rule-based connections and reinforcement tools
• Automated drawing production with customizable templates and standards
• Material takeoffs, reports, and fabrication outputs to support production
• Libraries for stairs, ladders, platforms, and handrails, plus utilities for clash checks and model review
• Interoperability with common BIM and CAD formats to coordinate with analysis/design tools and project partners
• Suitable for buildings, industrial facilities, and infrastructure projects requiring high-quality detailing and efficient delivery
