Defining and calculating numerical values

When modeling, you can quickly define or calculate numerical values such as dimension constraints using the expression input field or the built-in numpad/calculator. These fields support basic arithmetic operations, allowing you to perform simple calculations directly in Shapr3D.

For more advanced calculations, including unit conversions and order of operations, visit Variables and expressions.

Entering numerical values

You can define values in both 2D and 3D views by entering them directly into parameter labels using the parameter input field or numpad/calculator.

Note: Avoid commas as decimal separators to prevent errors.

To define numerical values while modeling:

Keyboard and mouse/trackpad

• Hover over the tool parameter label and enter a value to automatically open the input field.
• To finalize, press the Enter key.

Touch and pen

• Tap the tool parameter label to open the input field.
• Tap the numpad button to open the numpad/calculator.
• Tap the numbers to enter a value.
• To finalize, select the checkmark.

Perform basic arithmetic

You can enter simple calculations directly in the field or use the built-in numpad/calculator when defining numerical values.

Input field

To perform a basic calculation:

• Enter an arithmetic expression directly in the field.
• Press Enter, and the evaluated result will replace the expression.

Example: Entering 10 + 5 automatically displays 15.

Supported operations:

• Addition (+)
• Subtraction (-)
• Multiplication (*)
• Division (/)

Numpad/Calculator

To perform calculations using the numpad/calculator:

• Enter values and calculations as you would on a standard calculator.
• To finalize the result, select the checkmark.
