Modify a rebar set locally using modifiers

Modify a rebar set locally using modifiers

You can use modifiers to modify a rebar set at certain locations only.

For example, you can create a local property modifierrebar set modifier that can be used to locally change the properties of certain reinforcing bars in a rebar set

to only change the properties of certain bars in a rebar set, or you can create hooks or threading by adding an end detail modifierrebar set modifier that can be used to create hooks or threading for certain reinforcing bars in a rebar set

The rebar set end detail modifier affects the nearest end of the reinforcing bar.

, or you can split rebar set bars with a splitterrebar set modifier that can be used to split the reinforcing bars in a rebar set and to create reinforcement splices

.

You can also create secondary guidelines for the rebar set. With a secondary guidelinerebar set guideline that can be used in addition to the rebar set primary guideline to modify the geometry, direction, and spacing of reinforcing bars in a rebar set

Rebar set secondary guidelines can be used to create curved reinforcing bars or to define a different spacing at the start and end of the rebar set reinforcing bars, for example.

you can define a different spacing at the start and end of the rebar set bars, for example.

Modifiers are lines, or polylines that may have corner chamfers. Modifiers are projected to rebar set leg faces. Each modifierline or polyline that can be used to locally modify reinforcing bars in a rebar set

Rebar set modifiers can be rebar set property modifiers, end detail modifiers, or splitters. Also rebar set secondary guidelines behave like rebar set modifiers.

Polyline modifier may have corner chamfers. Each rebar set modifier only affects those rebar set reinforcing bars that its projection touches.

then only affects the rebar set bars that its projection touches.

Note:

When you work with rebar sets, ensure that theDirect modification switch is active.

To select entire rebar sets, or bar groups or individual bars within rebar sets in the model, you can use the three reinforcement selection switches. Tekla Structures then shows the existing modifiers that affect the selected rebar set bars, and the direct modificationfunction that activates the mode where the model objects can be modified by using handles

Direct modification enables additional handles and modification options.

handles of the modifiers. Different modifiers have different colors as follows:

Modifier Color Example
Property modifier Light green
End detail modifier Magenta
Splitter Orange
Secondary guideline Light blue

An arrowhead symbolclose to the midpoint of each modifier indicates the direction of the modifier, pointing from the start towards the end of the modifier.

When you select a modifier, Tekla Structures indicates the rebar set bars that are affected by the modifier, and shows the other, unaffected bars as semi-transparent.

You can modify the modifiers by using direct modification, or by changing their 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.

or on the contextual toolbarfloating toolbar that contains commands for modifying the most common object properties

The user can customize the contextual toolbar.

The term mini toolbar is used in Tekla Structures until version 21.1.

. When you change the modifier properties, the properties of the rebar set bars change at the location defined by the modifier.

When you delete a modifier, the rebar set reverts to the state it had without the modifier.

Create a property modifier

Property modifiers are shown in light green.

  1. Using the reinforcement selection switches, select the rebar set bars for which you want to create the modifier.
  2. On the Rebar set contextual tab on the ribbon, clickProperty modifier.
  3. Define how you want to place the modifier in the model.

    Click the Picking mode button on the contextual tab to cycle through the picking modes and to select the picking mode.

    Thebutton indicates that you can pick one point, and thebutton indicates that you can pick multiple points. Thebutton indicates that the modifier will be created for the selected bars only.

  4. Depending on the selected picking mode, do one of the following:
    • Pick one point to create a single line modifier for the selected rebar set, bar group, or bars.
    • Pick two points to define the end points of a single line modifier. Then click the middle mouse button.
    • Pick multiple points to create a polyline modifier. Then click the middle mouse button to finish picking.
  5. To end the command, press Esc.
  6. To apply local modifications to the rebar set bars at the modifier location:
    1. Select the modifier.
    2. If you need to change the modifier geometry, drag the direct modification handles.
    3. Change the property modifier properties on the contextual toolbar or in the property pane.
    4. If you used the property pane, click Modify to save the changes.

Create an end detail modifier

End detail modifiers affect the nearest end of the bar, so by moving the modifier you can change the bar end that it affects. End detail modifiers are shown in magenta.

Tekla Structures displays the threaded bar ends in dark red.

  1. Using the reinforcement selection switches, select the rebar set bars for which you want to create the modifier.
  2. On the Rebar set contextual tab on the ribbon, clickEnd detail.
  3. Define how you want to place the modifier in the model.

    Click the Picking mode button on the contextual tab to cycle through the picking modes and to select the picking mode.

    Thebutton indicates that you can pick one point, and thebutton indicates that you can pick multiple points. Thebutton indicates that the modifier will be created for the selected bars only.

  4. Depending on the selected picking mode, do one of the following:
    • Pick one point to create a single line modifier for the selected rebar set, bar group, or bars.
    • Pick two points to define the end points of a single line modifier. Then click the middle mouse button.
    • Pick multiple points to create a polyline modifier. Then click the middle mouse button to finish picking.
  5. To end the command, press Esc.
  6. To apply local modifications to the rebar set bars at the modifier location:
    1. Select the modifier.
    2. If you need to change the modifier geometry, drag the direct modification handles.
    3. Change the end detail modifier properties on the contextual toolbar or in the property pane.
    4. If you used the property pane, click Modify to save the changes.

Create a splitter

Splitters split bars and create lap or crank splices. Splitters are shown in orange.

  1. Using the reinforcement selection switches, select the rebar set bars for which you want to create the modifier.
  2. On the Rebar set contextual tab on the ribbon, clickSplitter.
  3. Define how you want to place the splitter in the model.

    Click the Picking mode button on the contextual tab to cycle through the picking modes and to select the picking mode.

    Thebutton indicates that you can pick one point, and thebutton indicates that you can pick multiple points. Thebutton indicates that the splitter will be created for the selected bars only.

  4. Depending on the selected picking mode, do one of the following:
    • Pick one point to create a single line splitter for the selected rebar set, bar group, or bars.
    • Pick two points to define the end points of a single line splitter. Then click the middle mouse button.
    • Pick multiple points to create a polyline splitter. Then click the middle mouse button to finish picking.
    Tip:

    If you want to create the splitter at a rounded distance from a bar end, and the dimension shown is measured from the other bar end, hold down Shift when you are placing the splitter in the model to switch the measuring point to the other bar end.

  5. To end the command, press Esc.
  6. To apply local modifications to the rebar set bars at the splitter location:
    1. Select the splitter.
    2. If you need to change the splitter geometry, drag the direct modification handles.
    3. Change the splitter properties on the contextual toolbar or in the property pane.
    4. If you used the property pane, click Modify to save the changes.

Create a secondary guideline

You can create up to two secondary guidelines for a rebar set. Secondary guidelines are shown in light blue.

  1. Select a rebar set.
  2. On the Rebar set contextual tab on the ribbon, clickSecondary guideline.
  3. Define how you want to place the guidelinedefinition of the distribution and direction of the reinforcing bars in rebar sets

    The spacing of the reinforcing bars is measured along the rebar set guideline. The rebar set guideline can be a line, or a polyline that may have corner chamfers.

    in the model.

    Thebutton on the contextual tab indicates that you can pick one point, and thebutton indicates that you can pick multiple points. Click the button to change the picking mode.

  4. Depending on the picking mode, do one of the following:
    • Pick one point to create a single line guideline.
    • Pick two points to define the end points of a single line guideline. Then click the middle mouse button.
    • Pick multiple points to create a polyline guideline. Then click the middle mouse button to finish picking.
  5. To create another secondary guideline, repeat steps 3 and 4.

    If there are already two secondary guidelines in a rebar set, the tooltip of thebutton changes to Maximum number of secondary guidelines reached and you cannot create more guidelines.

  6. Press Esc to stop creating secondary guidelines.
  7. If needed, select a secondary guideline and modify its geometry and properties.

    For example, you can adjust the secondary guideline's length or spacing values.

    See also Distribute bars in a rebar set.

  8. To set a secondary guideline as the primary guidelinerebar set guideline that is created automatically when a rebar set is created

    , select the secondary guideline and clickSet as primary on the contextual toolbar.
Tip:

Alternatively, you can create secondary guidelines the same way as you copy other modifiers : hold down Ctrl and drag the primary guideline.

Create a modifier by copying

You can copy rebar set modifiers.

  1. Select a rebar set, bar group, or bar to show its modifiers.
  2. Select the modifier that you want to copy.
  3. Hold down Ctrl and drag the modifier to the desired location.

    Tekla Structures creates a new modifier when you release the mouse button.

  4. Select the modifier to modify its geometry and properties as needed.

Show or hide rebar set modifiers

If you have many rebar set modifiers in your model, it may be useful to only show some of them at a time and hide the ones that are not currently needed. You can show and hide modifiers according to their type.

For example, you can show the end detail modifiers only, and hide all property modifiers and splitters.

  1. Go to the Concrete tab and click Rebar display options.
  2. Do any of the following:
    • Click Property modifier visibility to switch the property modifiers on or off.
    • Click End detail modifier visibility to switch the end detail modifiers on or off.
    • Click Splitter visibility to switch the splitters on or off.

Alternatively, you can use the following advanced optionssettings used to customize Tekla Structures for specific companies, standards, users, or user groups

In Tekla Structures, advanced options are settings that are used, for example, in a specific project or geographical area, or by a specific company.

In Tekla Structures, advanced options usually begin with the initials XS and are followed by the name of the function, for example XS_BACKGROUND_COLOR.
