# COMOSYS 2026 > 3D Steel Detailing Software – Built for Automation Canonical: https://www.ramcadds.com/products/comosys Source: RAM CADDSYS product catalog — https://www.ramcadds.com/products Categories: bim-solutions / modular-volumetric / steel-design / concrete-design COMOSYS is a 3D steel detailing platform that carries modeling, analysis and design, detailing and drawing production in a single environment. Smart macros, automated connection placement and clash resolution replace the repetitive modeling work, and the shop drawings, bar bending schedules and CNC/NC files all generate from the same model — so the detail that was checked is the detail the line fabricates. COMOSYS is a general purpose structural analysis, design, and detailing software that integrates modeling, analysis and design, detailing, and drafting phases in a single environment. All kinds of structures with arbitrary complexity can be modeled using advanced modeling capabilities. A powerful finite element engine working behind the scenes ensures exact results while structural steel members can be designed according to American, European and Turkish codes. ## Key points - Built to fix the fundamental limits of traditional steel detailing software - Standard and complex connections come from the library rather than hand-modeling - Connects design, detailing, drawings, and CNC in one unified model - Removes repetitive manual work — IntelliConnect, IntelliClone, COMCLASH, and AutoAdjust handle it automatically - Model changes propagate automatically to macro-created elements — manually placed bars stay as drawn ## Why engineers pick it - **Structural Analysis + Design** — Integrated finite element engine for exact structural analysis results. Design steel members per American, European, and Turkish codes within a single environment. - **Steel Detailing** — Full 3D steel detailing with intelligent macros, automated connection placement, and CNC/NC file generation—streamlining the complete fabrication workflow. - **Cloud Fusion** — Cloud‑based collaboration tools enabling distributed teams to work on the same model simultaneously, improving coordination across design and fabrication teams. - **Concrete** — Comprehensive rebar and precast concrete detailing capabilities fully integrated into the same modeling environment as the steel workflow. - **Tank** — Specialized tank modeling and detailing module for storage tanks and pressure vessels with automatic drawing generation and material takeoffs. - **Drawings** — Automatic drawing generation directly from the 3D model—shop drawings, assembly drawings, and general arrangement drawings produced without manual drafting. ## Capabilities - **Intelligent Macros** — Parametric macros capture repetitive detailing tasks and replay them across similar structural members, reducing modeling time dramatically. Record once, apply thousands of times. - **IntelliConnect** — Automated connection placement engine that recognizes member geometry and applies the correct connection type from the library without manual intervention. Supports bolted, welded, and hybrid connections. - **IntelliClone** — Clone entire structural zones or assemblies with full intelligence—copies adapt to the target geometry, preserving connection logic and detailing rules without rework. - **Extensive Connection Library** — Thousands of pre‑configured structural connections covering standard and complex configurations.

Plans, elevations, sections, and detail sheets are generated automatically with title blocks, dimensions, and BOM tables. - **Automate Connection Design** — Structural connection design automation checks capacity, applies code requirements, and sizes welds and bolts—removing manual calculation from the detailing workflow. - **Ancillary Steel Work** — Dedicated tools for secondary steelwork including handrails, staircases, grating, caged ladders, and cable trays—fully integrated into the main 3D model. ## Questions ### What is COMOSYS? COMOSYS is a comprehensive 3D structural analysis, design, and detailing software platform that integrates modeling, analysis, detailing, and drawing production in a single environment. It is used by structural engineers and steel fabricators worldwide. ### What does COMOSYS stand for? COMOSYS stands for COMprehensive mOdeling SYStem. The name reflects the software's core mission: to provide a complete, integrated environment for structural modeling from concept to fabrication. ### What is COMOSYS used for? COMOSYS is used for steel detailing, rebar detailing, precast concrete detailing, structural analysis and design, automatic drawing production, and CNC/NC file generation for steel fabrication. ### Are COMOSYS tutorials available? Yes. COMOSYS training is available through RAM CADDSYS CAMPUS, which provides structured courses covering modeling, detailing, connection design, and drawing production. On-site and remote training options are available. ### Why is COMOSYS better than traditional detailing software? The repetitive modeling work runs to rules rather than by hand: IntelliConnect places connections, IntelliClone repeats them across the structure, COMCLASH resolves interferences and AutoAdjust re-fits members when geometry moves. The drawings, bar bending schedules and CNC/NC files then come off that same model, so a change is made once rather than chased through separate drawing and fabrication files. ### Is COMOSYS similar to other steel detailing software? COMOSYS covers the same core workflow as leading steel detailing platforms: model, connect, detail, drawings, NC output. It differs in how much of that runs to rules rather than by hand, and in keeping analysis, detailing and fabrication output in one environment. ### Does COMOSYS model complex connections? Yes. COMOSYS includes an extensive connection library and an automated connection design engine. It handles standard framing connections, moment connections, base plates, and custom complex connections including multi‑member nodes. ### Why choose COMOSYS for 3D rebar detailing? COMOSYS provides a unified environment for both steel and rebar detailing, eliminating the need for separate software. The rebar module supports complex slab, beam, column, and wall reinforcement with automatic bar scheduling and drawing output. Note: automatic updates to placed rebar apply to macro‑created elements only; manually placed bars stay static when the structural model changes. ### Does COMOSYS support IS 800 steel detailing? Yes. COMOSYS supports Indian Standard IS 800:2007 for hot‑rolled steel member design and detailing, alongside American (AISC) and European (EN 1993) codes. Shop drawings, connection details, and BOMs are generated in a format suitable for Indian fabrication practice. ### Is COMOSYS available in India? Yes. RAM CADDSYS is the authorized distributor for COMOSYS across India, GCC, and Singapore. We provide licensing, local implementation, training through RAM CADDSYS CAMPUS, and ongoing technical support for Indian detailing firms and fabricators. ### Can COMOSYS generate shop drawings? Yes. COMOSYS generates shop drawings, assembly drawings, general arrangement drawings, and erection drawings automatically from the 3D model. Every drawing stays synchronized with the model — when the structural design changes, drawings of macro‑placed elements regenerate automatically. Title blocks, dimensions, BOMs, and weld symbols are included. ### Does COMOSYS work with Tekla models? Yes. COMOSYS exchanges data with Tekla Structures through IFC (Open BIM) round‑trip and standard CAD formats (DWG, DXF). You can import a Tekla model into COMOSYS for further detailing or export a COMOSYS model to Tekla for coordination — preserving member geometry, sections, and assembly data. ### Does COMOSYS generate Bar Bending Schedules (BBS)? Yes. The rebar module auto-generates Bar Bending Schedules directly from the 3D rebar model — with bar marks, shapes, lengths, weights, and totals formatted to Indian practice. BBS regenerates automatically when the macro‑created reinforcement is updated; manually placed bars must be refreshed individually. ### How does COMOSYS compare on total cost of ownership? The cost that matters is licence plus the man-hours a job actually takes. Weigh saved modelling and drawing time, how much drawing cleanup is left, and whether DSTV/NC output runs without rework.
