Tianzheng Structural Software is designed for structural construction drawing and design, fully supporting the latest AutoCAD graphics platforms. Currently, the structural information model based on Tianzheng structural objects serves as the core of the Tianzheng software series. Developed by Tianzheng’s R&D team with extensive user feedback, this software features custom entities for components such as beams, columns, and walls, seamlessly integrating with architectural, plumbing, heating, and electrical disciplines.
The T20V8.0 version supports both 32-bit AutoCAD 2010–2016 and 64-bit AutoCAD 2010–2022 platforms, delivering stable, efficient, and powerful structural drawing capabilities.
T20 Day Normal Structure v8.0 is the latest structural drawing software in the series, known for its stability, high execution efficiency, and powerful features. It supports the latest AutoCAD 2022 graphics platform and is the core software for structural information modeling within the Tianzheng series. Primarily used for structural construction drawing and design, it offers comprehensive tools for designing plates, beams, walls, columns, steel reinforcement, stairs, and more.
This software simplifies the drawing and editing of beam, column, and shear wall components, as well as the layout and editing of floor slabs. It excels in internal building structural drawings, supporting both the import of building modules and flat drawing parts to significantly enhance user efficiency. The user interface is clean and intuitive, with extensive text annotations that appear when hovering over components, making it accessible even for beginners by clearly explaining each tool’s function.
Compared to previous versions, T20 Tianzheng Structure v8.0 introduces many new features and optimizations, including Word document reading, WPS export, text extraction, block extraction, and block base point modification. It offers full compatibility with AutoCAD 2010–2022, ensuring seamless cooperation with various AutoCAD versions and aiming to boost designers’ productivity.
Tianzheng Structure T20V8.0 Activation and Installation Guide
- Download and run T20 Asd V8.0, the standard T20 structural software, then accept the license agreement. (Note: The official version has been updated.)
- Select the installation path, typically defaulting to
C:TangentTAsdT20V8sys24x643, and follow the installation steps until completion, then exit the installer. - Copy the patch file
tch_initstart.arxto the installation directory, replacing the existing file (default path:C:TangentTAsdT20V8sys24x64). - Launch the software and associate it with AutoCAD.
