There may be times when you sketch a level line and want to offset its bubble from the rest of the level line.
The end of the line near the bubble has drag controls.
Selected level with drag controls
Bubble dragged from level line
When you move the bubble end out of line, the effect appears only in that view, no other views are affected. 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 level lines. The cursor also snaps as the segments form straight lines.
