Modeling (M) Mode
Parametric Tower Modeling
Users can model structures using an intuitive graphical user interface powered by DirectX 11 and OpenGL 2.0 for increased speed and capabilities and generate executive and customizable formatted reports in Microsoft Word and Excel worksheets.
The VTS® software is a technology built on a ribbon-based interface, offering a streamlined design element where tools, commands, and options are conveniently organized into tabs and groups for effortless access and navigation.
The ribbon-based graphical user interface of the VTS® software allows to create, analyze and design large and complex models quickly and easily. Models can be shown as lines, wire frames, or can be rendered as 3D solids. Functionalities of the VTS® program allow to generate automatically detail elements in an automatically generated mesh perimeter. An object transparency option is available for various components such as current selection, solid members, plates, surfaces, spatial objects, panels.
Engineering (E) Mode
Structural Analysis & Design
Engineering of transmission lattice towers and electrical substations is performed seamlessly within VTS®, aligning with the ASCE standard. The software offers comprehensive structural analysis capabilities, including P-Delta, nonlinear, buckling, frequency, seismic, and dynamic analyses, with fully integrated design verification.
VTS® accelerates structure creation using an expansive library of panel types and parametric tools. Automatic generation of wind and ice loads is supported per the selected design code, while a rich repository of panel, rigid connection, and diaphragm prototypes streamlines the modeling process.
Results can be reviewed numerically or graphically, with color-coded charts that clearly visualize limit states across the entire structure or targeted members. All geometric and design parameters — including slenderness ratios and force coefficients — are computed automatically, but remain user-editable through intuitive graphical or tabular interfaces. Member grouping by shared properties further simplifies both modeling and interpretation.
Fabrication (F) Mode
Smart, customizable fabrication model
The fabrication phase involves performing fabrication operations on structural components such as cuts, notches, holes, bolting plates, connection design, and welding.
The Fabrication phase uses the structural model directly from Engineering Mode to generate a complete, production-ready fabrication model. VTS® automates detailing for direct bolt connections, splices, base plates, cap plates, gussets, step bolts, and more, minimizing manual work and ensuring accuracy.
Fabrication operations such as cuts, notches, holes, bolting plates, and welds are intelligently applied, with connection designs optimized for real-world manufacturing. Users retain full control to modify details via intuitive graphical or tabular tools.
The result is a fully detailed structure, ready for fabrication output, reducing errors, accelerating delivery, and maintaining full design integrity.
Detailing (D) Mode
Bill of Materials & Drawings
The Detailing phase focuses on generating all required drawings for fabrication, including 2D and 3D manufacturing drawings, engineering drawings, and detail drawings. VTS® extracts these directly from the fabrication model, ensuring consistency and precision across every component.
Editable DWG files and NC (Numerical Control) outputs are created automatically and can be exported directly, ready for CNC machine tools and shop-floor production.
