Slab properties
Similarly to the rafters in the roof, it is possible to define slab with beams. In the Beam properties dialog you can switch on the building up of beams and their representation in 2D.
Build up beams
By switching this option on the program builds up the beams. This will appear in the 3D model only when the Slab beams option is selected in the Build 3D model dialog.
2D representation
This option allows you to see slab beams on the floor plan. Beams are connected a slab layer. You can specify this connection in the Layer of beams field.
Beams are visible on the floor plan (by switching on the 2D representation option) only when the layer to which the beams are connected is activated.
Beam representation with centerline
With this option, beams can be represented by their centerlines on the floor-plan.
Delete and rebuild all beams
An existing slab with beams can be modified by the Slab shortcut menu - Slab framing commands. After you have carried out modifications with these commands, the original state can be reset by this option.
Coloring of slab
With the selection of a color you can represent a slab with a solid hatch on the floor plan:

In the beams dialog you can specify the properties of beams. |
Distance between layer and beam bottoms
Here you can set the distance between the bottom surface of the beams and the bottom surface of the layer of beams. If you specify a negative distance, the beams will appear below the slab layer.
You can specify the A distance between slab and beam ends and the B beam gap (see the figure in the dialog).
Cross-section - C, D
The cross-section profile of the beams is rectangle, which values can be set. Beside a rectangle cross section, you can choose any other profile as cross section from the profile library.
Creating slab with beams
Creating of slab with beams goes the same way as the creating of simple slab.
If the 2D representation option is switched off or the displayed slab layer is different from the layer to which the slab beams had been connected in the properties dialog, beams and their direction are represented only with a symbol:
Switched off Switched on
In the slab properties dialog you can specify a solid hatch for the slab representation on the floor plan.
Modify the slab beams
Slab beams can be modified by the Slab framing shortcut menu commands. These commands are similar to the Roof framing commands.
Modify direction
With this command you can modify the direction of the beams. Of course, this command deletes and rebuilds all beams, thus you will lose all of your modifications you made before.
