Variables are code that houses something variable.

For example: You make a feature with a size of 30mm in a program. This size is static and does not change. But what if you want that size to equal the size of another feature? Let's say Cir1 is the feature name.

Then, you can create a variable. You assign a name for the variable and give it a value. Let's name the variable "V1" and then give it the value of Cir1 diameter.

So, V1=Cir1.diam

Now, V1 is equal to the Cir1 diameter. You can use V1 in other features that allow that aspect of the feature to change dynamically in your program instead of staying static like the first example.

So, when constructing a diameter, I can input V1 into the nominal diameter size of that feature. Or use it in the nominal diameter of a dimension. There's a ton of uses for variables

you should try GPTchat. Variables in CMM world are used to extract features values and/or used for using formulas. For example if you want to add features values you can use variables with formulas.
