On the Design Quilt tab, you can zoom in on an area of your quilt to see the details.
The Zoom Out tool will reduce the view of the quilt. If you are currently in a Zoomed In view, clicking the Zoom Out tool once will return the screen view to the previous zoom level. Once the worktable is back to its original zoom level, you can continue to zoom out further seeing your quilt in a smaller size with each click of the tool.
The Refresh tool will redraw the worktable to clean up any leftover graphics on the screen. Click the Refresh tool once to apply the tool.
The Fit to Worktable tool will bring your zoom level back to the original, default zoom level of the screen. Click the Fit to Worktable tool once to apply the tool.
