The patcher's grid can help you enforce alignment of objects.
Click the Grid button in the Patcher window toolbar or choose Grid from the View menu.
When Snap to Grid is enabled, the top-left corner of an object will be forced to be on a grid intersection point when drag it.
Click the Enable Snap to Grid button in the Patcher window toolbar or choose Snap to Grid from the View menu.
While resizing an object, hold down the Command (Mac) or Ctrl (Windows) key. The bottom-right corner will be snapped to the grid. This works whether or not Snap to Grid is on.
