Data mapping expressions
Each data mapping formula begins with an equal sign (=) and contains expressions that are a combination of functions, constants, variables, and operators. The formula produces a new value, or a field identifier to select data mapped to an object. For information about the functions available, see Worksheet functions.
Constants
Constants can be logical values, numerical values, or text strings.
|
Constant |
Description |
Examples |
|
Boolean |
Values are used for Boolean parameters, and are either true or false |
TRUE FALSE |
|
Integer |
Positive or negative numbers and 0, written as numbers with no decimal point or apostrophes |
4 125 |
|
Rational number |
Real number values, written as a number with a decimal point and no apostrophes |
3.14 -12.0 248.141539 |
|
Text |
String values enclosed within apostrophes |
‘Unstyled Wall’ ‘INTERNAL’ ‘NOTDEFINED’ |
Variables
Variables represent data from Vectorworks objects. They can be combined with constants, function results, and other variables by using operators. The variable type (name) is the same as that of the data source type.

Notation |
Examples |
|
Parameters from a plug-in object |
'ObjectName'.'ParameterName' If the parameter is a pop-up field, the variable returns the localized value. To use the universal value instead, use the OBJECTDATA function: OBJECTDATA('Universal Value', 'Object PIO Name', 'Field Name') |
'Door'.'Config' 'Column2'.'Column ID' 'Pilaster2'.'Struct Type' OBJECTDATA('Universal Value', 'Column2', 'Struct Type') |
|
Vectorworks name |
OBJECTDATA('General Name') |
OBJECTDATA('General Name') |
|
Data fields from a record |
'RecordName'.'FieldName' If a record by that name isn't attached to the object, the FORMATFIELD function takes the default value for the field: FIRSTNONEMPTY('RecordName'.'FieldName', FORMATFIELD('RecordName','FieldName')) |
'MyRecord'.'Price' 'Plant Record'.'Latin Name' |
|
Data fields from styles |
Style.'FieldName' Supported data fields: Name (the name of the style) Mark Function Description Exterior (Boolean) Load-Bearing (Boolean) Fire Rating Combustible Construction (Boolean) Compartmentation (Boolean) U-Value Acoustic Rating Cost Index System Cost Index Code Model Manufacturer |
Style.'Function' Style.'Name' Style.'Fire Rating' |
|
Data fields from components in wall, slab, or roof styles |
Use the appropriate worksheet function, depending on the field desired: COMPONENTNAME(ComponentIndex) OBJECTDATA('Component', 'Function', ComponentIndex) OBJECTDATA('Component', 'Class', ComponentIndex) COMPONENTTHICKNESS(ComponentIndex) COMPONENTLAMBDA(ComponentIndex) COMPONENTUVALUE(ComponentIndex) To automatically assign the index during the export process, replace the parameter ComponentIndex with T=INDEX. The ExportOptions Pset must be mapped or attached to the object and one of the following property fields must be set to ON: Export by Components or Export Separate Instances. |
COMPONENTNAME(1) OBJECTDATA('Component', 'Class', 1) OBJECTDATA('Component', 'Function', T=INDEX) COMPONENTLAMBDA(T=INDEX) |
