To modify rebar sets by using leg faces, you first need to make the leg faces visible.

1. Ensure that the Direct modification switch is active.
2. On the Concrete tab, click Rebar display options > Leg face visibility.
3. Select a rebar set.

   Tekla Structures shows the leg faces. Tekla Structures also shows the bar layer numbers of the rebar set on each leg face, for example LN=1.

   

4. Move the mouse pointer over a leg face and click to select it.

   Tekla Structures highlights the leg face in yellow.

   

You can use any of the following methods when you modify rebar set leg faces.

1. To move a leg face, drag it to a new location.

   The connected leg face planes remain intact.

   If you want the connected leg faces to follow the dragged leg face, hold down Alt when dragging. The size of the dragged leg face remains the same, but the connected leg face planes may change.

   If you want to detach the leg face from the connected leg faces, hold down Shift when dragging.

2. To move an edge of a leg face, drag the edge to a new location.

   The connected leg faces follow, if possible.

3. To create a parallel copy of a leg face, hold down Ctrl and drag the leg face.
4. To create a new, connected leg face, hold down Ctrl and drag an edge of the leg face.

   

5. To add a new leg face at a part face or pour object face, click Add leg face on the contextual tab on the ribbon, and then select the part face or pour object face.
6. To create a new leg face on the basis of its corner points, switch Picking mode to , click Add leg face on the contextual tab on the ribbon, and then pick points to indicate the leg face corners. Click the middle mouse button to finish picking.
7. To add a new corner point to a leg face, drag a midpoint handle.

   

8. To remove a corner point from a leg face, select the point and press Delete.
9. To modify a corner chamfer of a leg face, select the corner point, and then select the chamfer type and enter the chamfer dimensions on the contextual toolbar.

   

   

10. To remove a leg face, select it and press Delete.
11. To define an additional offset between a leg face and the bars, select the leg face and enter a value for Additional offset on the contextual toolbar, for example, .

    A negative value moves the bars outside the concrete.

12. To flip bars over to the other side of a leg face, select the leg face and click Flip bar side on the contextual toolbar.

    

    Note that after flipping, Tekla Structures searches for concrete on the other side of the leg face to create a concrete cover and apply the concrete cover settings. If there is no concrete, the concrete cover thickness will be zero.

13. To change the order of the bar layers at an individual leg face, select the leg face and adjust the layer order by using the following buttons on the contextual toolbar:

    • Click to move the bars to the outermost layer.

    • Click to move the bars one layer outwards.

    • Click to move the bars one layer inwards.

    • Click to move the bars to the innermost layer.

    Alternatively, you can enter a number in the Layer number box in the property pane, and then click Modify to save the changes.

    The smaller the layer number, the closer to the concrete surface the bar layer is. You can use both positive and negative numbers.

    These modifications override the layer order settings of the entire rebar set.
