Using the calculator

To call the calculator, click Analysis and then, in the Utilities group, click (Calculator). Depending on the option selected in the System Settings dialog box (click > > ), Creo Elements/Direct Modeling displays either a standard calculator (the default) or an RPN (Reverse Polish Notation) calculator.

The calculator provides the ability to measure 3D and 2D geometry and to do a variety of math calculations using these measurements or other user-defined figures. Numerical values can be cut and pasted to/from other Creo Elements/Direct Modeling commands to save retyping.

The stack of registers starts with x at the bottom and goes up through y, z and finally to the t register. Each register (colored dark blue) contains a single numeric value.

The calculator:

• Measures distances, radii, angles and other 2D and 3D properties using a variety of measurement options. Results of the measurement are displayed and saved as numeric values in the calculator menu for further operations.

• Converts between inch and metric values.

• Provides both basic (add, subtract, multiply, divide) and advanced math functions (trigonometric, logarithmic, etc).

• Stores and recalls numeric values.

• Allows calculated values to be used as input for other Creo Elements/Direct Modeling commands. These can be scalar or 2D or 3D vector values.

• Accepts input values from the keyboard or the graphical number pad of the calculator menu.

• Provides the ability to manipulate the numeric stack. This includes: rolling the stack up and down, switching X and Y values, clearing the X value or the entire stack, and editing the numbers in the stack.

How to use the calculator

• Move your cursor to any of the cells and type numbers to enter, or modify, the value that is displayed in the cell. The light blue x,y,z and t buttons on the left put the register value into other Creo Elements/Direct Modeling commands. The xy and xyz buttons on the right put 2D (x,y) or 3D (x,y,z) vector values into other Creo Elements/Direct Modeling commands.

• Use the light blue mm->in and in->mm keys to convert the X register value to the desired unit.

• Use the blue number tablet (keys 0-9) to enter new values for calculation.

• Use the green Sto Rcl key with any of the blue number keys (0-9) to store and recall the value of the X register.

• Use the green R keys to scroll the numeric stack up or down.

• Use the green X<>Y key to switch the contents of the X and Y registers.

• Use the red Clx key to clear just the X register, the red Cl key to clear all of the registers, or the red <- key to delete the last digit from the X register.

• Use the yellow Enter key to save the register contents.

• Use the dark blue + - * / keys for addition, subtraction, multiplication and division.

• Use the scroll bar to see the additional math functions. There are several groups of additional math functions:

◦ Dark Blue (measure) - shown by default

◦ Yellow (trigonometry)

◦ Green (logarithm)

◦ Light Blue (polar/rectangular conversion and others)

The calculator does not measure infinite construction geometry.
