在核心功能与稳定性方面，新版本引入了钢拱架建模与 TBM UTR 竣工模型（As Built） 两大亮点功能，支持依据管片环位置及旋转数据反向生成精确的数字孪生体。同时，软件同步强化了配套的量算报告输出，并彻底修复了此前版本中打开材质编辑器时触发的程序崩溃，以及穿孔器（perforators）的相关错误。这些改进确保了工程师在面对复杂隧道掘进与结构深化设计时，能够拥有更高效、更稳定的数字化交付体验。

The OpenBuildings development team is pleased to announce the availability of OpenTunnel Designer 2026 (26.00.00.83) is the first and only purpose-built software for tunnel modeling and design.

The latest update focuses on three critical areas of tunnel engineering: structural precision, workflow integration, and digital twin accuracy.

OpenTunnel Designer is a comprehensive tunnel information modeling application built on OpenRoads technology addressing the geometric layout, connection to analysis and design, visualization and documentation for conventional and mechanized (TBM) tunnels at any scale of tunnel project. Built using MicroStation CONNECT Edition PowerPlatform and the Civil Framework technology, it allows you to collaborate more efficiently across disciplines, facilitating data re-use across the tunnel life cycle from concept to design and analysis to construction, and all the way to maintenance and operations. OpenTunnel Designer features several custom modeling tools geared to rapidly build accurate physical tunnel models, tied together parametrically, allowing for instant updates to the tunnel based on potential changes to roadway/rail geometry. OpenTunnel Designer leapfrogs the need for proficiency in 3D drafting, by allowing you to parametrically define, re-use and assemble components making the tool easy to use for tunnel, structural engineers as well as roadway/rail engineers. Preliminary cost estimates provide quick insights into structure costs, and you can quickly leverage the tools in the product to rapidly develop realistic renderings for project pursuits or public presentations.

This series breaks down the newest capabilities designed to reduce project risk and improve constructability in complex underground infrastructure. Watch to see how enhanced modeling for steel arches, “as-built” TBM tapered rings, and seamless ProStructures interoperability empower engineering teams to deliver more robust, cost-effective designs.
