To find your the Opacity tool within Artisan® please follow these steps:
1. Select your item in Artisan®.
2. Look right below the ribbon at the top and you will see a smaller menu otherwise known as the Quick Access Toolbar.
3. There is a button that is black and white checkered. That is the opacity tool button. Please click on that button.
Reminder: If you are in Basic mode, you will not see this smaller menu (aka the Quick Access Toolbar) and therefore will not be able to use the Opacity Tool.
