What is LTS

Model. Analyse. Design. Optimise. Automate. Detail.

Lunia Tech Structural Software (LTS) is a comprehensive structural engineering platform developed by Deskfine Software Limited for analysis, design, optimisation, automation, and detailing. Powered by Finite Element Analysis (FEA), LTS enables engineers to model, analyse, design, and verify a wide range of structures, including buildings, towers, culverts, trusses, and other structural systems.

LTS is built to make structural engineering efficient, traceable, and auditable — from the initial model and loading assumptions through analysis, design checks, detailing, and final documentation.

With real-time interoperability with leading engineering platforms such as Revit, ETABS, and Tekla Structures, LTS integrates naturally into modern structural engineering workflows. Engineers can iterate quickly, validate design assumptions, and maintain clear visibility from model to analysis, design, and final deliverables.

Why choose LTS

Engineers choose LTS for its ability to handle complex structural geometries, automate demanding engineering calculations, and deliver clear, traceable results that support confident design decisions.

LTS provides powerful modelling capabilities, from orthogonal and custom grid systems to mapped DXF import and direct element transfer between CAD and 3D modelling environments. Advanced analysis solvers and real-time 3D visualisation provide clear insight into both the structural model and its analytical behaviour, helping engineers work faster, reduce rework, and maintain control throughout the design process.

At the core of LTS are its design and detailing engines. Structural elements can be designed efficiently to the selected design standards, with automated reinforcement detailing, Bar Bending Schedules (BBS), steel connection design, fabrication drawings, and construction-ready documentation.

Design calculations are presented in a clear, modern, and auditable format, allowing engineers to review assumptions, applied loads, analysis results, design checks, and governing criteria at any stage of the workflow. LTS also provides practical learning and reference material to support students, graduate engineers, and experienced practitioners.

LTS brings accuracy, speed, flexibility, and automation together in a single structural engineering environment, helping engineers move efficiently from model to analysis, design, detailing, and documentation.

Fast Modelling

LTS provides flexible modelling tools designed to accelerate the creation of RC and steel structures. Engineers can build models using orthogonal grid systems, mapped DXF import, direct element transfer between CAD and 3D environments, or LTS's purpose-built structural generators.

Built-in modelling environments for portal frames, culverts, towers, and 2D trusses allow engineers to generate common structural systems quickly without building every element manually. 2D trusses can be drawn, designed, and seamlessly transferred into the 3D structural environment for further analysis and integration.

From concept geometry to a complete structural model, LTS is designed to reduce repetitive modelling and get engineers into analysis and design faster.

Accurate Loading & Analysis

LTS supports comprehensive loading systems covering gravity loads, including dead and live loads, as well as lateral and dynamic actions such as wind and seismic loads. Automated load combinations can be generated and remain fully user-editable, giving engineers control over how loads are applied and combined.

With advanced analysis solvers and flexible result views, LTS enables engineers to set up models efficiently, evaluate structural behaviour, and refine designs throughout the project workflow.

The analytical model delivers reliable structural results that flow directly into design and verification. Analysis results such as member forces, reactions, displacements, stresses, and other response quantities are used by the design engines to perform code-based checks and sizing, while the same results are available through interactive visualisation for clear interpretation of structural behaviour.

Automated & Controlled Design

LTS provides comprehensive design capabilities for reinforced concrete (RC) structures, including foundations such as pad, combined, mat and strip footings, as well as columns, beams, solid and ribbed slabs, and staircases.

For steel structures, LTS supports the design of portal frames, roof trusses, multistorey buildings, crane structures, and towers. Automated and user-controlled design checks cover purlins, braces, rafters, beams, columns, rails, and steel connections, giving engineers full control over design parameters, code requirements, and member selection.

The design process combines automated code checks with user control, allowing members to be assessed, optimised, and refined efficiently. The result is verified and optimised member sections, clear utilisation checks, and design outputs ready for detailing, fabrication, and documentation.

Reports & Detailed Documentation

LTS generates comprehensive, structured design reports that present the modelling assumptions, loading, load combinations, analysis results, design parameters, code checks, and governing results in a clear and traceable format. Engineers can review and audit the complete design process without having to reconstruct the calculations manually.

Construction drawings are generated directly from the designed model, keeping documentation consistent with the final structural design. Reinforced concrete elements are automatically detailed with reinforcement layouts, dimensions, annotations, schedules, and Bar Bending Schedules (BBS), providing a clear link between design and construction documentation.

For steel structures, LTS provides detailed connection drawings and fabrication documentation, with support for DSTV/NC data to facilitate the transfer of approved steelwork information to fabrication workflows.

From analysis and design to detailing, drawings, schedules, and fabrication data, LTS keeps the entire structural documentation process connected to the model.
