40 years of trusted, productive engineering.
Virtual Tower Structures® takes substation structures from 3D model to shop floor in one program: ASCE 10 and ASCE 48 analysis and design, automatic connections, shop drawings, bills of materials and NC files.
One program, from model to shop floor
VTS Virtual Tower Structures® is an integrated environment for the structural analysis, design, fabrication and detailing of electric substations and distribution structures such as lattice gantries, columns and beams.
Instead of passing a model from an analysis program to a separate detailing package, VTS works from one model. The structure you analyze and check to ASCE 10-15 and ASCE 48-19 is the same one used to generate connections, gussets, base and cap plates, bolts and step bolts.
Connections update automatically when members change, clash detection catches interferences before fabrication, and shop drawings, assembly drawings, bills of materials and NC files are extracted directly from the fabrication model.
VTS = M + E + F + D
VTS organizes the work into four modes that share the same model. Move from modeling to engineering, fabrication and detailing without exporting, re-entering or redrawing your structure.
Build lattice gantries, columns and beams with wizard-driven parametric tools.
Output: engineering model
Analyze the structure and check every member and connection to code, with results shown numerically or graphically.
Output: verified design
Turn the engineering model into a build-ready fabrication model with connections generated automatically.
Output: fabrication model
Extract every drawing and file the shop needs directly from the fabrication model.
Output: drawings, BOM & NC files
One model, four modes. End-to-end integration with complete data integrity.
Structure types
Analyze and design lattice gantries, substation structures and lattice transmission towers to ASCE 10-15 and ASCE 48-19.
Model lattice columns and beams joined by rigid beam-column connections, with diaphragms along the beams and bent or welded legs.
Build substation steelwork from individual columns and beams, with a primary-secondary configuration that simplifies large substation models.
Generate self-supporting and guyed lattice towers with automatic legs, bracing and connections, then configure crossarms, extensions and auxiliary framing.

Capabilities
Modeling, analysis, design, connections, fabrication and detailing for electric substations, in one integrated Windows desktop program.
Wizard-driven parametric tools generate complete 3D models of substation structures and lattice towers, with full control over every segment and panel.
Comprehensive analysis with fully integrated design verification. Every geometric and design parameter, including slenderness ratios and force coefficients, is computed automatically and remains editable through graphical or tabular interfaces.
VTS uses the analyzed model directly to generate every connection automatically, with full control to adjust them manually.
Turn the engineering model into a build-ready fabrication model, with every plate, bolt, cut and hole defined.
All drawings and files are extracted directly from the fabrication model, so they stay consistent with the analyzed design.
The Operational Framework · M + E + F + D
In VTS, Modeling, Engineering, Fabrication and Detailing are four modes of the same model. Switch between them at any time: geometry, loads, results, connections and drawings stay linked, with nothing exported, re-entered or redrawn between modes.
Model data carried forward
Build lattice gantries, columns, beams and transmission towers with wizard-driven parametric tools.
Carries forward to Engineering
Analyze the same model and check every member and connection to code, with results shown numerically or graphically.
Carries forward to Fabrication
The analyzed model becomes a build-ready fabrication model, with connections generated automatically.
Carries forward to Detailing
Every drawing and file the shop needs is extracted directly from the fabrication model.
Output: drawings, BOM & NC files
