1.  Purpose and description

This is a plugincomponent that is developed using Tekla Open API

Plugin is a .dll file and loaded inside Tekla Structures process.

Plugins can be started from the applications and components catalog.

component able to create “U” shaped edge reinforcement by using bent meshes.

The number of created meshes and maximum length of each created bent 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.

depends on the length of the standard mesh in the cataloguser interface for displaying or modifying information in categorized lists

For example, profile catalog and shape catalog are catalogs.

. If the last mesh would not have at least two crossing bars the length of the first mesh will be half of the standard mesh length.

2.  System requirements

Environments:                         Any

3.  Installation

To install the extension:

  1. Download the zipped msi-file. Make sure to download the package compatible with your Tekla Structures version.
  2. Extract the zip package
  3. Right click the msi-file and select option “Install” or just double click the file
  4. Follow the instructions

4.  Usage

To use the extension:

  1. Click the component “Edge Reinforcement  With Meshes” in the component catalogcatalog that contains all system components and custom components, and the macros and applications

  2. Pick part, typically a 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.

    or 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.

    kind of part.
  3. Identify the edge by picking the start and end points at the edge reinforcement.

Please note that the meshes are created between the two picked points which might not be the full length of the edge (see Figure 1).

5.  Extension settings

5.1. Tab page ‘Parameters’

In this tab page you are able to set all dimensions and other main information used to control the creation of the meshes.

Property Description


These are the start and end offsets for first and last meshes.


Please note that the end offsets are measured from picked input points and not from the actual end of the edge.

This is the free space between two meshes when two or more meshes are needed.


In some cases when either the first or last mesh is not a full length mesh and the length has to be adjusted to avoid mesh cut at cross bar location the tool may need to use slightly smaller free space that is given on the dialog.

Here you can give the cover thickness and the leg lengths for the mesh.


If only one leg length is given the other one will be equal to given one by default.


Please note that the cover thickness at top is measured from picked input points and not from actual edge.


Location of longitudinal bars

With this setting you can control on which side of the bent (=crossing) bars the longitudinal bars are placed.


When longitudinal bars are placed outside all cover thickness values are measured from outermost longitudinal bars.

Mesh, Grade, Select

Here you can type the mesh catalog name and grade or you can click the button ‘Select’ to open the mesh catalog browser dialog.


After you have selected the mesh from catalog tree and clicked the ‘OK’ button on the mesh catalog browser dialog the fields ‘Mesh’ and ‘Grade’ will be filled with selected values.


Please note that only catalog meshes can be used. Any values given for the “custom mesh” will not be used by this tool.

Bending radius

Here you can give the bending radius for mesh bending.

5.2. Tab page ‘General settings’



In this tab page you are able to set remaining properties of the meshes.

Property Description


This is the numbering prefix for all created meshes.

Start number

This is the numbering start number for all created meshes.

Use mesh catalog name

With this setting you can control which value will be applied to mesh name.


When the option ‘Yes’ is selected the mesh name will be equal to mesh catalog name and you will not be able to fill in anything into the field ‘Name’.


To give another name for the mesh select option ‘No’ when you can give whatever name for the mesh.


Here you can give the mesh name. Please note that this field is enabled and will be used only when the value ‘No’ is selected for above field.


Here you can give the class for all created meshes.
