Expression Constructor

The expression constructor is called when you need to specify a link with a variable. For example, when inserting a variable into a text field or associating the value of a Product Structure data cell with a variable.

The content of the window depends on its method of calling. For all call methods, all existing document variables will be displayed in the window.

See the features of filling the Expression Constructor window in the relevant sections.

Selecting the External only, Real, Text and Hidden checkboxes only determines the presence of the appropriate type of variables in the list. You can select a variable using , or by entering its name in the Expression field. When you enter the name of a nonexistent variable, the dialog for creating a new variable is called.

After confirmation, a new variable with the specified value is created and the constructor window closes.

If necessary, you can specify an expression consisting of several variables, as well as use preset functions to work with variables.

 

The last selected function will be added to the constructor window.

The buttons of the last selected functions will be displayed until the current session with T-FLEX CAD is finished.
