The document provides instructions on how to access and use the equation interface in SW (SolidWorks). 1. **Opening the Equation Interface**: - Method 1: Navigate to Tools → Equations. - Method 2: Use the design tree to reveal hidden equations. 2. **Using Global Variables**: - Create a global variable named "Length" with a value of 100. - Create another global variable "Width" with a value of 75 based on current dimensions. - Set a dimension to equal another global variable (e.g., "Length"). - Link a dimension to a global variable. - Create a global variable "Diameter" defined as "Width/2" and link it to a dimension, enabling automatic updates. - Add global variables for measurements and file properties, which will appear in the design tree. - Link to external files to modify model dimensions by changing the external file.

How to open the SW equation interface

Method 1: Tools --> Equation

Method 2: Call up the hidden equation through the design tree (as shown below)

Equation interface: Create a global variable "Length" and set the value to 100.

How to use global variables in equations

Situation 1: Create a global variable named "Width" based on the value, with the variable value specified as the current size 75.

Situation 2: Set a certain size to the value specified by a global variable parameter, for example, as shown below specified as "Length".

Situation 3: Link a certain size to a global variable.

Situation 4: Create a global variable "Diameter" and set the equation to "Width/2", and set the value of "D1@Sketch1" to "Diameter". Check auto-rebuild, modify the value, and you can change the model. (If not auto-rebuild, you can manually rebuild, the shortcut is Ctrl+B)

Situation 5: You can add global variables for "Measurements" and file properties. Displayed in the design tree.

Situation 6: Link to external files, modify the model size by modifying the external file.
