9.4.1. Slab properties

Before placing the slab, you have to define slab properties.

Right-click the Toolbox   Slab tool to access these properties, or use the Modeling menu-Properties - Slab command.
After you activated this command, a dialog box with slab properties pops up.

 

General properties

Firstly, you can modify general slab properties, like color, line width, layer and line type.

&For the description see Chapter 3.2.1. Specifying general properties.

Sets

You can save your customized slab properties into sets and you can store sets in the environment. This way you can use the desired slab structure in any of your drawings. If you click on the button, the pre-defined slab sets will be displayed on the right side of the dialog box.

 

&For the description see Chapter 3.2.3. Using sets of properties.

Slab material properties

Under general properties, you can set slab material and slab-to-slab height.

Enable the Same materials option to assign the same material to all 3 sides of the slab.

 

 

  • material for top surface - floor

 

  • material for side surface

 

  • material for bottom surface - ceiling

 

If you click on the Material name, the Material dialog box will pop up.

 

 

&For the description see Chapter 3.2.2. Material properties.

 

 

  • Enter the relative height of the slab as compared to the active floor.

Slab width:

-0,30

Angle of the sloped slab

In the case of sloped slabs you can modify slope angle in the Slab properties dialog box. This field is grayed (i.e. disabled) when defining general properties.

Slab cut

You can set automatic cutting of slabs by walls or by the roof.

 

The slab cuts down wall sections over the slab. You can use any of the following options to cut walls:

 

 

  • own floor,
  • all floors,
  • no cutting - the slab will not cut any wall
  • the slab cuts walls on its own floor and below.

 

This method is very useful if you want to create an arched slab and you want to cut walls so as to fit this arched slab.

 

2In the case of columns and other objects placed into the wall, slab cutting works only if you enable it in the object property dialog box. This means that you can cut any wall with a slab without cutting the chimney in the slab.

 

You can cut slabs with roofs in the following ways:

 

  • the roof cuts the slab at each floor
  • the roof does not cut the slab

 

If you draw an alpine-style building for instance, it is necessary to enable the cut all floors option:

 

No cutting:

Cutting by the floor:

 

2You can see the result of these two cutting options if you enable the Wall - slab - roof cutting option in the Build3D model dialog box.
