Parameter Set Name

A description text for the structure.

Material Code

You can select the roof material from the list.

Pitch

The pitch is typed in a text window either as a ratio or in degrees. The ratio can be typed either as the ratio of the height and width of the slope or as a decimal number, for example 1/4 or 0.25. If the pitch is typed in degrees, the numeric value is followed by the letter A, for example 45A.

Eave Type, Fascia Height

You can create different eaves by changing the parameters Eave type and Fascia height:

• Vertical

  Fascia height = 0, Fascia height = h

  

• Perpendicular

  Fascia height = 0, Fascia height = h

  

• 45 deg bevel

  Fascia height = h

  

Eave Height

The value of this parameter can be calculated with the Calculate button, when values have been selected for the Distance from eave to limit line, Top floor surface height, Room height on limit line and Roof thickness parameters.

Distance from eave to limit line, Top floor surface height, Room height on limit line, Roof thickness

Type values for these parameters in the text fields. These parameters are used to calculate a value for the Eave height parameter using the Calculate button.

H1= Eave height
H2= Room height on limit line
T= Roof thickness
D= Distance from eave to limit line
