A common mistake among SOLIDWORKS users is overlooking the built-in calculator and resorting to an external one when entering dimensions, custom properties, and more.
Often, users need to perform simple calculations — like applying 70% of a value or solving long equations and unit conversions.
What usually happens is the immediate use of a phone or computer calculator. This not only disrupts the workflow but also increases the chances of making errors when copying values back into SOLIDWORKS.
The good news? SOLIDWORKS has a built-in calculator that can handle these calculations quickly, accurately, and directly, making your work more efficient and seamless.
How to Use the SOLIDWORKS Calculator
The SOLIDWORKS Calculator is one of the software's most intuitive tools.
Whenever you enter a dimension — whether in sketches, features, or entities — you can simply type the equation directly into the input box. SOLIDWORKS will do the math for you.
For example, if you want to set a dimension as 1/5 of a height of 100 mm, just type 100/5.
The value will automatically be calculated and displayed as 20 when you confirm the entry.
The Calculator Supports Addition, Subtraction, Multiplication, Division, and Even Exponents
More Than Just Calculations: Unit Conversions
In addition to math operations, the SOLIDWORKS Calculator also performs unit conversions automatically.
Suppose you're modeling in millimeters but have a measurement in inches.
Instead of using an external calculator to multiply by 2.54, just type the value followed by the unit. For example, 3in.
SOLIDWORKS will automatically convert it to millimeters, according to the unit system defined in the document properties.
More Accuracy, Fewer Errors
By using the SOLIDWORKS Calculator, you eliminate the need for external tools, reduce the risk of typing mistakes, and speed up your workflow — whether you're doing simple calculations or more complex operations.
