Changing a global variable in SolidWorks is a fundamental skill that every user should be familiar with. Whether you need to modify dimensions, update design parameters, or create flexible models, understanding how to change global variables will significantly enhance your productivity and efficiency in SolidWorks.
What are Global Variables?
Global variables in SolidWorks are user-defined values that can be used to drive dimensions and control features within a model. They act as placeholders for numeric values, allowing you to easily modify multiple dimensions simultaneously by changing just one variable.
Accessing Global Variables
To access the global variables in SolidWorks, follow these steps:
- Open your desired part or assembly file.
- Navigate to the Equations folder in the FeatureManager Design Tree on the left-hand side of the screen.
- Double-click on the Global Variables folder to expand it.
Modifying Global Variables
To modify a global variable, simply double-click on its name within the Global Variables folder. A dialog box will appear, allowing you to change its value.
Alternatively, you can right-click on a global variable and select Edit Equation... This option provides additional functionality such as defining equations and linking variables.
The Benefits of Using Global Variables
Bold text:
- Simplified Design Modifications: By utilizing global variables, you can easily modify multiple dimensions at once, reducing design time and effort.
- Design Flexibility: Changing a single global variable can update all associated dimensions throughout your model. This flexibility allows for quick design iterations and adaptations.
- Improved Design Automation: Global variables can be linked to Excel spreadsheets or other design automation tools, enabling parametric design and speeding up the design process.

Best Practices for Using Global Variables
- Consistent Naming Conventions: Use descriptive names for your global variables to ensure clarity and ease of understanding.
- Documenting Changes: Keep a record of changes made to global variables, as they directly impact the dimensions and features within your model.
- Test Iteratively: Before finalizing your design, test different values for your global variables to ensure that they yield the desired results.
In conclusion, global variables are a powerful tool in SolidWorks that allow you to efficiently control and modify dimensional values within your models. By understanding how to access and modify them, you can streamline your design process, improve design flexibility, and automate repetitive tasks. Incorporating best practices when using global variables will further enhance your workflow and help you create robust models in SolidWorks.
