Adding Custom Properties

To add custom properties:

  1. Click in the first blank cell under Property Name, then enter a name or choose one from the list.
  2. Select a Type from the list.
    To move between cells in the table, press Tab or Enter, or click in the cell you want to move to.
  3. Under Value / Text Expression, enter a value for the custom property that is compatible with the selection in the Type cell.
    For Value / Text Expression, you can enter values or select values from a list.

    If you add a date (for example, DrawnDate), as a custom property, the software does not require you to enter a date for Value / Expression. However, if you do not enter a date, Microsoft interprets the empty field as 1/1/1800 when you view the document's custom properties in File Explorer.

    When you define a custom property that includes a single or double quotation mark (‘ or “), enter an @ sign in front of the quotation mark to ensure that the expression evaluates correctly. For example: 2@" X 2@" X 1/4@".

    The @ sign also applies when referencing a Property Name that includes a quotation mark. For example, if you have a file property whose name is Length12”, you must add an @ sign in Value/Text Expression for that property.

  4. Press Tab or Enter.
    The value of the property displays under Evaluated Value.
  5. In the Linked column, click the box to link the custom property to the parent part.
  6. Repeat steps 1 to 5 as required, then click OK.
    The custom property is added.
