3D Structural Modeling
Frames, slabs, walls, supports, stories, Cartesian and curved grids, snapping, copy/mirror/divide/join tools, physical section shapes and responsive Plan, Elevation, Story3D and Full3D views.
structural design station
Model. Analyze.
Feel the Structure.
DTabs Pro brings structural modeling, analysis, accelerated result exploration and design workflows into one focused desktop environment—built for engineers who want clarity from geometry to response.Exclusive Addition is BNBC2020(for Bangladesh) & OBC2025(for Oman)
One engineering workspace
Built around the structural workflow.
From grids, stories and physical sections to finite-element analysis and graphical result exploration, DTabs Pro keeps the model and its engineering meaning connected. Independent dual viewports let you inspect the same model from different scopes at the same time.
Loading & Mass
Load patterns, cases and combinations, frame and area loading, mass-source definition, diaphragms, springs, response-spectrum and time-history function workflows.
Compiled Analysis
Native compiled structural-solver integration with static, modal and dynamic analysis workflows, P-Delta preparation and scalable finite-element model generation.
Accelerated Results
GPU-oriented retained result scenes, displacement animation, shell contours, frame forces/stress, reactions, deflection and independent result exploration in dual windows.
Design Workflows
Integrated reinforced-concrete and structural design workflows with frame, slab/shell and wall-oriented result and design exploration developed around code-based engineering checks.
Export Report & Drawing Easily
Export Professional Report & Necessary Drawings Easily with DTabs Pro.
Dual-window intelligence
Two views. One model. Independent control.
Keep a clean plan contour in one viewport while orbiting the complete analytical model in the other. DTabs Pro's dual-window workflow supports independent Plan and Full3D exploration before and after analysis.
Analysis & response
Explore what the structure is doing.
DTabs Pro combines numerical analysis with an interactive graphical layer designed to make structural response easier to inspect—from global movement down to member and shell behavior.
Linear StaticLoad cases, combinations, reactions, displacement and member response.
Modal AnalysisNatural modes, periods, mode shapes and modal participation workflows.
Response SpectrumResponse-spectrum functions(BNBC2020,OBC2025 included), modal combination and directional result exploration.
Time HistoryTime-history functions, result steps and structural response exploration.
P-DeltaSecond-order analysis preparation and associated modal workflow integration.
Eigenvalue Buckling AnalysisDetermine the critical load at which a structure becomes unstable — essentially, the load that causes buckling.
Staged Construction AnalysisStaged Construction Analysis made easy with DTabs Pro.
Exclusive Design CodesExclusive Design Codes added for Bangladeshi & Omani Engineers along with BS Codes & American Codes.
Design, Engineering Report & Detailing
Design flows into Engineering Report & Detailing.
Design,Report & Detailing are integrated with the model and analysis results so engineers can move from demand to detailing without leaving the structural workspace.
Frame,Slab,Wall,Foundation
Code-oriented design results, member checks and graphical result review tied directly to model.
Design Report
Professional Design Report can be generated with few Clicks.
Detail Drawing
Detail Drawing Can be generated for Foundation, Slab. Beam & Column Detailing to be added.
Visual environment
Engineered for light and dark.
The same analysis remains readable in both themes. Result palettes, contours, structural geometry and interface surfaces adapt so the workspace can match the engineer's preferred environment.

Full license release
1 Year.Full DTabs Pro License for your Feedback.
The license is machine-bound and starts its 1-year full-license period on first launch. This build is fully functional for checking the software. As pre-release engineering software, all inputs and outputs should be independently checked carefully. Your findings are helpful in making the software more reliable and bug-free, and your suggestions are highly appreciated as more features are added. Please send feedback and suggestions to decode.mhk@gmail.com
Developer
Humayun Kabir Jony
Structural Engineer with 15+Years of Experience. Graduated from Chittagong University of Engineering & Technology (CUET), Chittagong, Bangladesh.
DTabs Pro is developed as an engineering-focused structural software platform with an emphasis on practical modeling, numerical analysis, responsive visualization and integrated design workflows. The project is developed under DECODE BD with the goal of creating a modern structural desktop environment that remains clear and efficient as models become more complex.
