You can access a calculator function as you work with the program. You can use either the QuickCalc calculator interface or the command prompt calculator.
With the QuickCalc calculator, an interface that looks and functions like a hand-held calculator, you can perform mathematical, scientific, and geometric calculations, convert units of measurement, manipulate the properties of objects, and evaluate expressions.
By entering an expression in the command prompt calculator, you can quickly solve a mathematical problem or locate points in your drawing.
