Data type

When creating object properties the Data type field defines the values that the property can accept.

Data type	Valid value	Expression	Expression example
Double	Real number	Double or formula	Door style.Lining depth/Door style.Material.Thermal conductivity
Integer	Integer	Integer or formula	ceil(Nominal length)
String	Internal data is stored as a string of characters.	References and formulas in curly brackets, any characters	{Beam style.Name}x{Cross section overall height}x{Cross section overall width}
Length	The value in millimeters	Number of formula	Number of steps*Tread depth
Area	The value in square meters	Number of formula	Net floor area*0.5
Volume	The value in cubic meters	Number of formula	Net volume*1.1
Mass	The value in kilograms	Number of formula	Net mass+Total mass of reinforcing bars
Angle	The value in decimal degrees	Number of formula	asind((Object baseline top elevation-Object baseline bottom elevation)/Nominal length)
Boolean	True/False	Formula with the result 0 - No, 1-Yes	(Wall thickness>300) ? 1 : 0
Logical	True/False/Unknown
Enumeration	A value from a list created by the user. To create a list of suggested values, enter it in the enumeration Values field. Press ENTER to separate the values.

The data type can not be changed when you edit the properties. If an expression is set for a property, its result must match the data type.

To change the list of values of the Enumeration type:

1. In the All Properties tab, select the property and click Edit Property... .
2. Change the list of values.
3. Click OK.
4. After that, you will be prompted to update the values of the properties assigned to the objects. To discard the changes, click Cancel.

When creating schedules and legends, as well as when working with a tag, the values of length, volume, and mass specified in the object properties can be converted to other units of measurement in the metric system.
