A range of commercial brands is available in EmbroideryStudio for a wide variety of machines and design types. The My Hoops option allows you to define a filtered list of those hoops you have available for use. If you are using a hoop not appearing in the hoops list, the Options > Hoop dialog also lets you define your own and save for later use.
EmbroideryStudio provides options for auto-centering hoops around the geometric center of the design or start needle position. You can also turn off auto-centering to ensure the hoop does not move from its original position. You can also define a point on the design that the hoop will center around.
