Communication Tower Design Software

Capture your Workflow

Efficiently design and model towers, such as lattice towers and guyed masts, as well as equipment such as antennas, mounts, and linear appurtenances, with powerful 3D modeling. Bentley’s tower applications are built to specifically suit your tower workflows and optimize design time. With both graphical and text-based definitions of tower structures, you can design and complete projects faster than ever.

What is OpenTower Designer?

OpenTower Designer is communication tower design software that allows you to leverage a comprehensive library of panel types and ancillary equipment that enable quick creation of the structure. Automatically generate loads for any number of directions with user-defined topographic configurations and quickly perform design checks. Create reports with virtually any output – from structure data to loading analysis results to design capacities for members and bolts.

When designing in accordance with U.S., Euro, or Australian design standards, you will save time and complete projects faster through automatic scenario creation by combining geometric layers, equipment grouping, and loading criteria. You can also create a physical model by applying hierarchical modification layers with revision history on top of the base geometry using built-in business logic.

Configure bracing libraries

Create customizable XML libraries. Configure an XML file to create your own customized libraries for panel bracing, torque arms, and even truss legs. You may also use built-in bracing types that can be extended and configured externally.

Create realistic graphics & models

Use a modern graphical environment to get a realistic visualization of the model. Discrete and linear appurtenances are drawn to scale on your 3D tower model. Visualize precise positioning of the equipment, including feed lines at any elevation and linear attachments.

Customize equipment libraries

Customize the robust equipment library, which includes antenna, dish, TME, feedlines, and attachments equipment from all major manufacturers using built-in capabilities.

Design connections

Define member connections with various bolt patterns, including pre-defined bolt configurations. Automatically consider the effects of connections on member design calculations and check connection efficiencies.

Define external loading

Define cluster formation of linear ancillaries as well as miscellaneous ancillaries including resistance ancillaries. Use options like ATTACH command to define load distribution criteria from an equipment to the tower.

Design tower foundations

Design tower foundations (U.S., Euro, and Australian code) for tower legs and guy support points, including pad-pier, drilled pier, guy anchor foundations and mat foundations. Automatically design foundations for the most critical load cases for different criteria and review the foundation rating.
