Release Notes - Tekla Structures 2017 SP12

Defect number Development area Description
TSAC-2771, TSAC-2769 Concrete components

In Floor layout, the component attribute file list is now properly shown for all components. Previously, it was not properly shown for 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.

, for example.

TSAC-2410 Concrete components

Seam applicator now again loads custom componentcomponent that the user creates and uses for creating model objects whose composition the user can modify as a group


TTSD-23264 Import, export, interoperability

The IFCfile format commonly used in BIM that facilitates software interoperability

IFC is an open specification developed by the IAI (International Alliance for Interoperability).

Model can be exported into an IFC file.

object conversion update now keeps the user-created part cuts.

TTSD-22387 Import, export, interoperability

When manually importing a new profile through the Modify Profile Catalogcatalog that displays profiles and information on the profiles

In addition to the available profiles in the respective Tekla Structures environment, the user can add fixed or parametric user-defined profiles to the profile catalog. It is also possible to import profiles to the profile catalog.

dialog box using the Replace option, all parts in the model could sometimes get unintentionally modified. Now all unaffected parts remain untouched after the import.

TTSD-21384 Import, export, interoperability

In the IFC2x3 export, the surface treatmentbuilding object that represents finishing of a part

The term surface treatment is used in concrete detailing. For concrete parts surface treatment includes surface mixes, tiles, and flat finishes, such as troweling and sandblasting.

The term surface finish is used in steel detailing. For steel parts surface finishes include fire-proofing and unpainted areas.

to all faces of the part is now properly written to the IFCfile format commonly used in BIM that facilitates software interoperability

IFC is an open specification developed by the IAI (International Alliance for Interoperability).

Model can be exported into an IFC file.

Some incorrectly defined welds in the model caused crash in drawings when new section views were created. This has now been fixed.

TTSD-24940 Drawings

Tekla Structures does not crash anymore when modifying a drawing even if the 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.

definitions are missing from the objects.inp.
The User-defined attributes dialog box is not available at all in the drawing dialog box  if UDAs are missing from the environment. Previously,clicking the panel caused an applicationpart of Tekla Structures functionality that is developed in order to extend the capability of Tekla Structures but that is not included in the Tekla Structures installation

Detailed object level settingsdrawing settings that affect the representation of selected drawing objects

Object level settings can be defined when creating a new drawing or when modifying an open drawing.

Object level settings can be use in a drawing or in a drawing view in order to change the representation of the chosen drawing objects.

were not applied if the name from the dialog box differed from file name for the given attribute.

When Secondary part(1) part that exists in a building object and that is connected to the main part

(1) Secondary part can be an assembly secondary part or a cast unit secondary part.

(2) input part that the user selects after selecting the component main part when creating a component

(2) A component can have none, one or more component secondary parts.

dimension direction
was set to Neighbor partpart that is close to a part that the drawing is made for but that is not in the same assembly or cast unit

The representation of neighbor parts is usually different from that of the part.

Neighbor parts can be used as reference in dimensioning.

in dimensioning properties, there was sometimes a crash when creating or modifying assembly drawings. This has now been fixed.

TTSD-21756 Drawings

Sometimes Tekla Structures showed an assert when a text was moved in a drawing using the Shift button.

TTSD-20433 Modeling

Selecting parts in large models is now much faster.
