There may be times when you sketch a grid line and want to offset its bubble from the rest of the grid line.
The end of the line near the bubble has drag controls.
Selected grid with drag controls
Bubble dragged from grid line
When you move the bubble end out of line, the effect appears only in that view. The segments created from dragging the bubble have a solid line style. You cannot change this style.
As you drag a control, the cursor snaps at points similar to the neighboring grids. The cursor also snaps as the segments form straight lines.
