Creating
or Editing a Data Mapping Formula
Creating
or Editing a Data Mapping FormulaA new mapping formula can be created for the selected IFC property. The current mapping can also be edited. As described in more detail in IFC Data Mapping Expressions, a mapping formula contains expressions with constants, variables, operators, and functions. A variable is a data source from Vectorworks, such as an object parameter, style data, record field, class name, or layer name. Functions can be math functions, string manipulation functions, conditional, and selector functions.
To create a mapping formula:
From the IFC Data Mapping dialog box, select the object, and then the current mapping for the object.
The current formula is displayed in Mapping for field.
Click Define Mapping.
The Define Mapping dialog box opens.
Minor syntax edits can be made directly to the formula. For example, add a prefix and/or suffix, or add concatenation or arithmetic operations to the formula. See Entering Formulas in Worksheet Cells for information about arithmetic operations.
► Click to show/hide the parameters.
Build the formula by selecting the mapping values and specific parameters from the lists.
Click OK.
The mapping formula displays in the IFC Data Mapping dialog box.
