TTSD-41488 Steel components You can now use the XS_USE_OLD_MACRO_INPUT_POINT_VISIBILITY advanced option to restore the old component input visibility in the rare case where the input points need to be selectable in the model view. Note that the setting only affects new component objects in the model, not the existing components. Add the advanced option to an .ini file, as follows: set XS_USE_OLD_MACRO_INPUT_POINT_VISIBILITY=TRUE

TTSD-40848 Import, export, interoperability Reference models: The local placement was written incorrectly in mh software, which is why the IfcElementProxy objects were scaled incorrectly in Tekla Structures. This has now been fixed.
TTSD-40509 Import, export, interoperability IFC2x3 export: The export now works also when you have defined a base pointthat has a negative north direction angle value.
TTSD-40453 Import, export, interoperability IFC2x3 export: The IFC2x3 export did not always export surface treatment. This has now been fixed.

TTSD-40674 Drawings The ASSEMBLY_POS attribute did not report any value when it was used in bolt marks in drawings. This has now been fixed.
TTSD-40631 Drawings In a rare case, a snapshot could contain erroneous lines causing a Tekla Structures application error. This has now been fixed.
TTSD-40629 Drawings Dragging dimensions in a drawing could cause an application error in some rare cases. This has now been fixed, and the application error no longer occurs.
TTSD-39632 Drawings The pull-out pictures now appear in rebar dimension marks on rebar sets.
TTSD-38664 Drawings When the location of one rebar was adjusted manually, some rebar marks, also from other rebars, were moving. This has now been fixed.
TTSD-38567 Drawings The default hatch scale when placing a hatch outside a view is now the same as it was in Tekla Structures version 2018.
TSAC-4888 Drawings The Grid labels command in drawings now works properly. It was previously not working in some versions of Tekla Structures 2020.
TTSD-40833 Tekla Model Sharing Previously, if Tekla Structures crashed or stopped working and you had to end the TeklaStructures process during write out in a shared model, you could not open the model again because of missing drawing files. This has now been fixed.
TTSD-41293 Reinforcement When you have the Create rebars by guidelines command active, the properties you change in the property pane are now used for the next rebar set you create.

TTSD-39559 Tools and components When working with custom components that contained other components, extra points were sometimes added. This has now been fixed. Additionally, the database diagnose and repair functionality has been improved so that extra points are cleaned away.
TTSD-20740 Tools and components When importing custom components, if one or more custom components in a .uel file fails to import, the successfully imported components are now available. Previously, they were only available after reopening the model or importing a new .uel file.

Recommended hardware for Tekla Structures workstations

The table below presents two different hardware configurations. The recommendations are mainly for desktop computers, but the same guidelines can also be applied when purchasing laptops. These hardware recommendations are based on proven set-ups that are used in testing Tekla Structures. Other set-ups can be used if they are more optimal for your intended use.
