Variables

You can use the Variable Table for a lot of things, especially for things that change depending on the type of garment you're making, like ease - which will change if you’re creating a dress/blouse, or a light jacket, or a warm winter coat. You can use the variables with conditional formulas to add different amounts, depending on the base measurement.

Think of the variables as unique measurements only for one specific project. The variables will generally be created on the fly, while creating your pattern draft, and aren't measured before you start.

Working with variables

1. To add a variable, open the Variables Table from the Menu ⇒ Measurements ⇒ Variables Table (Ctrl+T)
2. Click on the green plus (+) button to add a new variable
3. To remove a value, click on the minus (-) button
4. To add a formula, click on the $f(x)$-button
5. To change the order of the variables (important for the formulas), click on the arrow buttons.
   • You can use measurements and custom variables in your formulas. You can only refer to custom variables which are above your current variable in the list, otherwise you won't get correct results. So double check the order of your variables.

Important note:You can't use properties (length, angle, ...) from existing elements/objects such as lines and curves, as the variables are at the start of the pattern file before the drafting section. Using formulas referencing the drafting elements/objects will cause calculation in variable to break and revert to the value of 0. This may change in a future version.
