You can use the Variables area to define, store, and retrieve calculator variables.
Calculator variables can either be constants (coordinates/vectors, real numbers,
and integers) or functions. In the Variables area, you can
■ Click a calculator variable to display information such as value, type, and
description in the Details box at the bottom of the Variables area.
■ Double-click a calculator variable to load it into the QuickCalc Input box.
Additional operations are available on the shortcut menus in the Variables
area.
Create New Calculator Variables
You can create new calculator variables using the shortcut menus in the
Variables area. When defining new calculator variables in the Variable
Definition dialog box, the following rules apply:
■ Constants. Any expression entered in the Value or Expression text entry
box is evaluated before the calculator variable is stored. Calculator variables
that are defined as constants are available “globally.” You can access and
use global constants in different drawings and sessions.
■ Functions. Any expression entered in the Value or Expression text entry
box is stored as text. Functions are evaluated when used in the QuickCalc
Input box.
Create Global Constants
You can use one of the following methods to create global constants:
■ Enter an expression in the Input box using the format $variable_name=value.
For example, to define the golden ratio to 8 decimal places as a global
constant called Phi, enter $Phi=1.61803399 in the Input box.
■ Click the New Variable button in the Variables area title bar. In the
Variables Definition dialog box, click Constant and fill in the other boxes.
■ Right-click the Variables area. Click New Variable.
Access Global Constants
You can access global constants and pass them to the Input box of the
QuickCalc as follows:
■ Double-click a variable in the Variables area of QuickCalc.
