Engineering library update (November 2025)
Tekla Tedds Engineering Library update (November 2025 - version 27.07) is available in Trimble Downloads.
All Regions
2D analysis, Beam analysis
Enhanced to bring greater accessibility to member local deflections. It is now easy to view local member deflections in sketches and tables and include results in the output. Member deflection design can now be carried out for either global or local deflections depending on selection, where applicable. See regional information for calculations with design enhancements.
The Design Member Configuration dialog is improved to provide more guidance and provide better default support definitions for common conditions.
American Design
Steel 2D analysis & design (AISC360), Wood 2D analysis & design (NDS)
Enhanced to bring greater accessibility to member local deflections. It is now easy to view local member deflections in sketches and tables and include results in the output. Member deflection design can now be carried out for either global or local deflections depending on selection.
