Release Notes - Tekla Structures 2018 SP3

Parametric profiles now correct when modified in property pane

In Tekla Structures 2018 SP2, when modifying a parametric profilepredefined profile whose cross section dimensions the user can change by using parametric variables

in the property panecontrol element in Tekla Structures user interface in the form of a side pane window

The property pane can be used to show and modify the properties of model objects.

, the property pane changed the profile dimensions to some unknown numeric values.  This issue concerned both imperial units and metric decimal units, and could happen in any environment using them. This issue has now been fixed in Tekla Structures 2018 SP3. For more details, see Parametric profiles incorrect when modified in property pane.

New feature: Option to show a point cloud inside work area

In Tekla Structures 2018 SP3, when attaching a point cloudgroup of measured points that are imported to Tekla Structures as one unit

Point clouds can be placed by the model origin or by a defined base point.

, you can now select to show the point cloud inside the work areacertain portion of the model that is currently active for working on in a view

Tekla Structures indicates the work area using dashed lines. Since objects outside the work area exist but are not visible the user can set a certain sized work area so that the views of the model are simpler and quickly updated, for example.

only (Show inside work area only). If you change the work area, you can update the point cloud box to the changed work area by first hiding the point cloud and then setting it visible again.

Previously, when you cleared a value in the rebar set spacing zone properties in the property panecontrol element in Tekla Structures user interface in the form of a side pane window

The property pane can be used to show and modify the properties of model objects.

, clicking Modify caused Tekla Structures to crash. Now the property pane automatically validates the data in the spacing zone properties and you cannot click Modify anymore.

TTSD-16923 System and options

Previously, if you set the autosave interval less than 2, autosave was disabled. This has now been changed so that the smallest accepted value for the autosave interval is 2, both for modeling and for drawings.

If you try to enter a value smaller than 2, Tekla Structures automatically changes the value to 2.

Now such components are not updated during read in. The modelsharing.log lists these components and the reason why they were not updated.

TTSD-4757 Analysis and design

Exporting polybeams from Tekla Structures to Tekla Structural Designer is now possible with certain limitations. The export to Tekla Structural Designer uses the correct analysis position, but the exported alignment may not always be correct, i.e. the physical position in Tekla Structural Designer may not match the physical position in Tekla Structures.

Previously, if XS_ENABLE_REBAR_MARK_LEADER_LINE_BASE_POINT_OPTIMIZATION was set to TRUE, Tekla Structures optimized the base pointpoint in a model that is used to define a starting point in surveying and that is used as an anchor point in coordinate and height transformations

A Tekla Structures project can have several base points but only one of them can be the project base point.

Base points allow the use of another coordinate system needed for interoperability and collaboration. Base points can also be used in drawings, and in reports and templates. Model origin is the default base point in Tekla Structures.

Base points are also called control points.

In Tekla Structures, grids are used as an aid in locating objects in a model. The grid is shown on the view plane by dash-and-dot lines. It is also possible to show grids and grid line labels in drawings, and to modify grid properties in the drawings.

It is possible to have more than one grid in a model. For example, a large-scale grid for the entire structure, and smaller grids for some detailed sections.

TTSD-14900 Numbering

Previously, starting from Tekla Structures 21.1, the number of an unmodified part might change if another part became exactly the same in terms of numberingprocess of assigning position numbers to parts, cast units, assemblies, or reinforcement

In Tekla Structures, the position numbers assigned in the numbering are shown in marks and templates, for example.

. In numbering, the unmodified part received the same number as the modified part.
Now, if both the modified part and the unmodified part have or do not have drawings, the unmodified part will keep its number. If one of the part has a drawing and the other one does not, the number of the part that has a drawing will stay the same, and the number of the part that does not have a drawing will change.

Because of the missing break lines and/or detailing strips, the next modification of Floor layout created slabs without breaks and/or details. After this fix the break line and detailing strips create dummy construction lines and thus they will be preserved by Tekla Model Sharing and the Repair model commands.

TTSD-16906 Modeling

There is a new template attributeattribute in a template object that Tekla Structures uses to calculate and display information from a model database

Template attributes represent object properties.

ADDED_TO_POUR_UNIT to indicate how an object was added to a pour unitentity that combines together a pour object and the other building objects that need to be in place before cast-in-place concrete can be poured

The needed building objects can be reinforcement and embeds, for example.

.
The possible values are:
0 - unassigned and dirty (modified after the pour unit was resolved the last time)
1 - manually assigned
2 - automatically assigned

The attribute is in the template category in filters and in the template attributes for the following object types:
ASSEMBLY
BOLT
CAST_UNIT

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.


REBAR
SINGLE_REBAR
SINGLE_STRANDreinforcement that represents a group of wires spun together


STRAND
STUDbolt element that represents a metal rod or pin that is used to transfer loads

Studs and other bolt elements are listed in the bolt catalog.

A stud can be secured with two or more nuts and have threading at both ends, or it can be welded to steel parts, for example.

A stud is part of the bolt assembly.
