Add dimensions to reinforcement

Add dimensions to reinforcement

You can manually add dimension lines and dimension marks to reinforcing barreinforcement that represents a steel bar used to reinforce a concrete structure

The steel bars are usually ribbed and they are used to increase the tensile strength of concrete.

groups. When adding dimensions, start by using predefined dimension settings defined for your environment, and modify these settings for individual dimensions, if necessary. There are reinforcement dimension settings affecting the whole model in the Options dialog box. You can also add dimensions to reinforcing bar groups using the Rebar group dimensioning 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

.

Add dimension marks or dimension tags to rebar groups

Each reinforcing bar groupgroup of reinforcing bars that are side by side and have identical properties, except the possible variation in bar lengths

may have a dimension markpart of a dimension that displays the basic information about the building object measurements

A dimension mark can consist of a prefix, numerical value, and postfix.

or a tagged dimension mark. These dimensions are created based on predefined dimension properties that you have selected in File > Settings > Options > Drawing dimensions. The commands are available in GA drawings and cast unit drawings. You may want to add reinforcement dimension marks or tagged dimension marks especially in concrete cast unit drawings, where there is only one reinforced cast unit visible.

To add dimension marks or tagged dimension marks to rebar groups:

  1. To select the desired predefined settings, go to File > Settings > Options > Drawing dimensions , and load the desired predefined dimension properties files in Dimension mark settings and Tagged dimension mark settings.

    You can also select the representationthe way that the information included in a model is represented visually

    for tapered skewed and curved reinforcement group dimensions, and add a dimension lineline that visualizes the distance between the defined dimension points

    Separate dimensions can be combined into a longer dimension line.

    extension to dimension lines that have arrows. For more information, see section "Predefined reinforcement dimension settings in the Options dialog box" below.

  2. In an open drawing, right-click the reinforcing bar group and select one of the following dimension mark commands and pick a location for the dimension:

    Add mark > Dimension mark .

    Add mark > Tagged dimension mark

You can change the representation of the current rebar dimension after creating it by double-clicking the rebar dimension in an open drawing, and modifying the dimension content , appearance , and marks and tags as required. For example, you may want to add more tags, change dimension mark content, or select how to align tags in curved dimensions.

Add dimension lines to rebar groups

The Create dimension line command shows the distribution of the rebars in the group, and draws dashed lines from the dimension lines to the rebars when you drag the dimension outside the rebar groupgroup of reinforcing bars that are side by side and have identical properties, except the possible variation in bar lengths

. This command is available in GA drawings and cast unit drawings, but you may want to use it especially in GA reinforcement drawings, because they may contain a lot of parts with rebar groups, and you often need to show only one rebar from the group and drag the dimension line to a proper place to see everything clearly. This command creates dimensions based on the predefined dimension properties that you have selected in File > Settings > Options > Drawing dimensions.

To add dimension lines showing the distribution of the reinforcing bars to rebar groups:

  1. To select the desired predefined settings, go to File > Settings > Options > Drawing dimensions , and load the desired predefined dimension properties file in Dimension line settings.

    You can also select the representation for tapered skewed and curved reinforcement group dimensions, and add a dimension line extension to dimension lines that have arrows. For more information, see section "Predefined reinforcement dimension settings in the Options dialog box" below.

  2. Right-click a reinforcing bar group and click Create dimension line.

    Tekla Structures creates the dimension line.

  3. You can drag the reinforcement dimension line out of the reinforcement bar group.

    When you do this, Tekla Structures draws a dashed line from the reinforcing bar to the dimension line. If the new location is in the reinforcement area, the dimension mark follows the intersection of the reinforcement bar and reinforcement dimension line.

    To change the representation of the current rebar dimension, double-click the rebar dimension in an open drawing, and modify the dimension content , appearance , and marks and tags as required.

    Below is an example of a dimension line created with Create dimension line :

    Below is an example of the dimension line when it has been dragged outside the reinforcing bar group:

    Below is an example, where only one rebar of the group is visible, and the dimension line has been dragged outside the group.

Predefined reinforcement dimension settings in the Options dialog box

There are predefined settings in the Options dialog box in the Drawing dimensions settings affecting rebar dimensions and dimension marks. Settings are model specific and only affect the current modelmodel that is active in Tekla Structures

The current model can be a single-user model, a shared model or a working model.

. Changing the settings does not require Tekla Structures restart.

Option Description
Dimension mark settings Select which predefined dimension settings you always want to apply to dimension marks. These settings are used when you create dimension marks with the Add mark > Dimension mark command.
Tagged dimension mark settings Select which predefined dimension settings you always want to apply to tagged dimension marks. These settings are used when you create dimension marks with the Add mark > Tagged dimension mark command.
Dimension line settings Select which predefined dimension settings you always want to apply to dimension lines that you create with the Create dimension line command.
Dimension line extension length for line arrow

You can create line extensions in dimensions that have line arrows. Enter the length of the dimension line extension in the Dimension line extension length for line arrow box. This setting will be applied to all dimension that have line arrows.

No extension

Extension added

Tapered skewed reinforcement group Select whether skewed dimensions have skewed or horizontal representation in Tapered skewed reinforcement group .
Tapered curved reinforcement group Select whether curved dimensions have curved or horizontal representation in Tapered curved reinforcement group .

Examples of rebar dimensions

  • Below is a tapered skewed part, and skewed dimension representation is selected from Tapered skewed reinforcement group. The dimension line follows the shape of the edge that is closest to where you pick.

  • Below is a tapered curved part, and curved dimension representation is selected from Tapered curved reinforcement group :

  • Below is an example of curved orthogonalview projection that displays objects in right-angles projection

    In model view the size of the objects is the same despite of their distance to the viewing point and the zoom remains on part faces.

    :

  • You can also add middle tags in rebar dimensions. Here dual dimensions have been applied:

  • Curved dimension tags can be aligned by selecting one of the options in the Curved dimension tag type list in the Dimension properties dialog box:

    In the example below, only one rebar is visible, and rebar tags are aligned vertically:

    In the example below, the dimension tag follows the dimension curve:

  • Below is an example of curved orthogonal dimensions of a radial reinforcing bar group.

Add dimensions to rebar groups (Rebar group dimensioning)

You can add dimensions to reinforcing bar groups by using the Rebar group dimensioning application.

  1. Select the reinforcing bar groups.
  2. Click the Applications & components button in the side pane to open the Applications & components cataloguser interface for displaying or modifying information in categorized lists

    For example, profile catalog and shape catalog are catalogs.

    .

  3. Click the arrow next to Applications to open the applications list.
  4. Double-click Rebar group dimensioning.
  5. Select the Annotation type.

    The first option is meant for cases where two or more groups are not overlapping. The second and third options are meant for cases where the groups are overlapping. The third option is otherwise similar to the second one, except that the dimension text is in 90 degrees angle in relation to the actual dimension line.

  6. In Prefix for spacing value , enter the letters or text to be placed before the spacing value.

  7. In the Settings for distribution line , select the properties file that you want to use for the distribution line.

    You can control these properties by opening and modifying the properties file in the Dimension Properties dialog box.

  8. In Settings for note text , select the properties file that you want to use for the annotation text part other than the position text.

    You can control these properties by opening and modifying the properties file in the Text Properties dialog box.

  9. In Show position in text , select whether you want to show or hide the position text

  10. In Settings for position text , select the properties file that you want to use for the position text in the annotation.

  11. If you set Close dimension line to part ends to Default , the first annotation type is closed, and the other types are not. You can change this default behavior by selecting Yes or No.
  12. Go to the Advanced settings tab to control the relative locations and placing of various elements of the annotation.
  13. In First line spacing , enter a millimeter value to indicate the space between the dimension line and the first line of dimension text.

  14. In Next line spacing , enter a millimeter value to indicate the space between several lines of dimension text.

  15. Select Free text below text and enter a millimeter value to indicate the space between the last line of dimension text and the next dimension line.

  16. Select Dimension line spacing and enter a millimeter value to indicate the space between two or more dimension lines.

  17. In Tolerance for group width , enter a decimal value to override the default tolerance value of 50 mm.

    The idea is to have a common dimension line and multiple texts whenever the reinforcing bar groups have equal widths, which means that the difference in width is smaller than the tolerance.

  18. Click OK.
  19. Click the location on the reinforcing bar group where you want to place the dimensions.
