Create slab items

Slab items are individual slab panels that form parent slabs. You can create slab items either by bay, or by points. For more information, see the following instructions.

Select the slab type and specify slab properties

  1. On the Model tab, click the arrow under Slabs.
  2. In the list that appears, select the desired slab type.
  3. In the Properties window, define the slab item parameters for the selected slab type.
  4. Ensure that the Slab and Select bays properties are set according to your needs.

Specify the parent slab to which the slab item belongs

  1. In the Properties window, go to the Slab property.
  2. Click the arrow on the right side of Slab.
  3. In the list that appears, select whether you want to:
    • Create a new slab

    • Add to existing slab


      When you select this option, at the point of creating the slab item, Tekla Structural Designer checks if there is a existing slab in the plane with same properties.

      If Tekla Structural Designer finds an identical slab, the new slab item will be added to it.

      If Tekla Structural Designer finds two identical slabs, the closest one is used.

      If Tekla Structural Designer does not find an identical slab, a new parent slab is created.

    • Manually select the parent slab


      This option is only available in 2D views after one or more slab items have been placed in that view.

  4. When the slab item properties are defined, you can place the item either by bays or by picking points.

Create slab items by bay

You can only create slab items by bay in 2D Views.

  1. In the Properties window, ensure that the Select bays option is selected.
  2. Do one of the following:
    To Do this
    To add an individual slab item
    1. Click the outline of a bay bounded by beams or walls.

    To add slab items into all bounded bays
    • Drag a box that encompasses the bays.

    Dragging the box from left to right places items in those bays totally enclosed by the box.

    Dragging the box from right to left places items in all bays that are either enclosed by the box, or cross it.

    Holding down Shift while dragging creates a line instead of a box. Tekla Structural Designer places slab items in all bays that cross the line.

Create slab items by points

You can create slabs in both 2D and 3D Views.

  1. In the Properties window, ensure that the Select bays option is cleared.
  2. Click the start point of the slab item.
  3. Click other points that define the slab item outline.
  4. Double-click the final point to create the slab item.
