TTSD-28663 User interface

Previously, when you modified a UDAobject property created by the user in order to widen the range of predefined object properties

User-defined attributes are used when the predefined object properties are not sufficient but more properties are needed. For example, comment, locked, and erection status are user-defined attributes.

Export Unitechnik (79): Previously, when you exported braced girders within the STEELMAT block but with meshreinforcement that represents a mesh of steel bars in two perpendicular directions

In Tekla Structures, the reinforcement mesh bars in one direction are called main bars and reinforcement mesh bars perpendicular to them are called crossing bars.

filtered out, the reinforcement block was exported as empty. This has now been fixed.

TSAC-3543 Import, export, interoperability (concrete)

Export Unitechnik (79): The Double wallplate that represents a structure such as a wall or roof panel

In Tekla Structures, a panel is created by picking two or more points.

In cast-in-place concrete the term wall refers to a concept similar to panel.

turned
setting  on the TS configuration tab has been improved. The No option has been renamed to option No, one coordinate system and new option No, shell-specific coordinate systems has been added to export second shell in the Z direction from the bottom of the pallet upwards.

Export Unitechnik (79): The Extend contour and add formwork option on the TS configuration tab has been improved. Now, formwork is not added if there is already an embedbuilding object that represents an object that is to be cast into a concrete structure and that is used to connect structures or as an aid when constructing a structure

For example, a cast-in socket is an embed that is placed in concrete structures to allow parts to be fastened together on site. In Tekla Structures, embeds are typically steel parts and they are added to cast units as sub-assemblies.

with the same geometry. Also, the contour is not extended for electric tube embeds.

Export Unitechnik (79): When the BRGIRDER block is exported within the STEELMAT block, the STEELMAT insertion coordinates are now correctly adjusted in case the girder minimum coordinate points are outside the meshreinforcement that represents a mesh of steel bars in two perpendicular directions

In Tekla Structures, the reinforcement mesh bars in one direction are called main bars and reinforcement mesh bars perpendicular to them are called crossing bars.

TSAC-3488 Import, export, interoperability (concrete)

Export  Unitechnik (79): Braced girders modeled with only two chords are now correctly recognized and exported.

TSAC-3484 Import, export, interoperability (concrete)

Export Unitechnik (79): Previously, braced girders within the STEELMAT block were not exported when the STEELMAT block was otherwise empty. This has now been fixed.

TSAC-3447 Import, export, interoperability (concrete)

Export EliPlan file (68): All geometrical data with the Plotter and Pieces blocks are now exported rounded to the closest millimeter in metric environments.

TSAC-3418 Import, export, interoperability (concrete)

Export EliPlan file (68): Hollow core slabplate that represents a concrete structure

In Tekla Structures, a slab is created by picking three or more points.

Slab may be part of a floor, for example.

thickness is now read from the profile instead of the geometrical thickness (in case the complete top or bottom face is cut).

TSAC-3357 Import, export, interoperability (concrete)

Export Unitechnik (79): On the Reinforcement tab, you can now select to export braced girders within the STEELMAT block. By default, the braced girders are exported outside of the STEELMAT block.

TSAC-3171 Import, export, interoperability (concrete)

Export Unitechnik (79): On the TS configuration tab you can now set Export CONTOUR to Simplified, which exports a simplified contour using 4 x,y corner points of the element.

TSAC-2594 Import, export, interoperability (concrete)

Export EliPlan file (68): When using the Export using filter setting, the logging of excluded cast units has been improved.
