, and improvements in concrete components.

Defect number Development area Description
TSAC-5246 Concrete components

Embedded anchors (8): When a polygon thickening in the insulation layer was created around anchors, the anchors were created at the bottom edge of the thickening and not at the top edge. This has now been fixed.

TSAC-5206 Concrete components

Pad footingfooting that supports a single point of contact

Pad footing usually supports one column.

reinforcement (77)
: Previously, when the third zone had enough space for one rebar only, the rebar was not created. This concerned both the primary and the secondary bars. This has now been fixed. Additionally, you can now define in each zone that rebars are not created. The creation of just one rebar in each zone has been improved so that the rebar is now created in its proper position.

TSAC-5089 Concrete components

Rebar coupler: Previously, the component did not identify the primary and secondary rebars based on the given primary side point. This happened when the Rebar coupler component was added to a rebar set. Now this has been fixed.

TSAC-5088 Concrete components

Reinforced concrete(1) concrete structure which contains reinforcement designed on the assumption that the concrete and reinforcement act together in resisting forces

(1) Reinforcement in reinforced concrete is usually steel bars, wires, or welded wire fabric. It may also be structural fiber of some other material.

(1) In Tekla Structures, reinforced concrete is modeled with reinforcement objects.

(2) cast unit type where the concrete is formed, poured, and cured in its final position

stair (95)
: Anti-material created by the component is now always created in the correct position.

TSAC-4442 Concrete components

Lifting anchor (80): The assignment of the main part(1) part that exists in a building object and that determines the position number for the assembly or cast unit and the direction of assembly or cast unit drawings

(1) Main part can be an assembly main part or a cast unit main part.

(2) input part that the user selects first when creating a component

(2) Connections and details always have a component main part.

has been improved. Previously, the created lifting anchors could in some situations get a non-steel 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.

as the main part. This has now been fixed.

TSAC-5208 Steel components

Cold rolled sleeved (2): Previously, the component did not work correctly for steel sketched Z profiles. This has now been fixed.

TSAC-4879 Steel components

Joining plates (14): Previously, galvanizing holes were not created correctly in the second end platecomponent object that represents a plate welded perpendicular to the end of the component secondary part

. This has now been fixed.

TTSD-43115 Import, export, interoperability

Previously, rebars were excluded from pour units when the model containing the pour units was uploaded to Trimble Connect(1) application for information sharing and collaboration for construction projects that is based on the Trimble Connect platform

(1) Reference models are used in Trimble Connect application instead of using import and export.

(1) Trimble Connect application includes web, desktop and mobile clients, and the Sync tool, for example.

(2) Trimble’s platform for microservices in the cloud

(2) Trimble Connect platform’s microservices include services for uploading, storing, processing, and managing or consuming data. These services are meant to provide common solutions required by multiple applications.

The grid is defined by coordinates in 3D space. It is shown two-dimensionally on the view plane by dash-and-dot lines. A grid can be rectangular or radial.

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.

It is also possible to show grids and grid line labels in drawings, and to modify how they are shown in the drawings.
