Last updated August 4, 2020 by Martin Roclawski martin.roclawski@trimble.com

Tekla Tedds 2020 - Service Pack 2a/b


This update has been re-released to address a number of minor bugs introduced in the initial release - see [TEDDS-4820]2, [TEDDS-4835]3


If you are running a 64-bit version of Windows you will require both updates.

Tedds Application

The Duplicate document command which is one of the most frequently used commands in the Tedds Application has been enhanced to improve productivity. When the Duplicate command on the Home tab is now used on a document which belongs to the current project the new document will be automatically added to the project.

Visual Quality

When using a 4K display the 4x increase in pixels over a standard HD (1080p) display can provide a significant improvement in the visual quality for text, images and drawings in both the Tedds user interface and the documented output. This service pack includes more enhancements and fixes which ensure that Tedds is optimised for high resolution displays and some of those improvements will also be of benefit if your Windows Text Size setting is greater than 100%.

Other Updates


[TEDDS-4749]1 - Fixed calculation user interface button images for “Collapse” and “Expand” which were transposed.
[TEDDS-4659]1 - Added an option to prevent asterisks being converted to multiplication symbols in document output in order to resolve problems on some systems which do not display the multiplication symbols correctly.
[TEDDS-4769]1 - Fixed Date format control on the Tedds header options dialog to ensure that the items in the list use an appropriate height when Windows text size settings are greater than 100%

2D analysis

[TEDDS-4669]1 - Fixed the expression error “section name cannot contain the '*' character” when selecting some steel sections and the Tedds country setting is “Finland”, “Norway” or “Sweden”.

[TEDDS-4707]1 - Fixed to prevent an undefined variable error in the “Wood member analysis and design (NDS)” calculation related to "_SetMaterialDetails" due to the manual input of the material density. When combined with the Tedds Engineering Library (July 2020) update the enhancement [TEDDS-545]1 ensures that the density value is calculated automatically for sawn lumber and glulam and does not have to be entered manually.
[TEDDS-4799]1 - Fixed lumber type not being included in section source data for US flitch sections.

Tedds Application

[TEDDS-4366]1 - Enhanced the “Duplicate” document command so that when the source document is included in the active project the new document will be automatically included in the project after the source document.
