Snap to Grid/Items
Move a shape exactly to a grid point or edge of another shape.
Snap to Grid/Items
To enhance drawing speed and efficiency, you can display and snap to a rectangular grid. Snapping helps with precise placement of shapes. The grid is dynamically changed during zooming.
Show/Hide Subordinate Shapes
Expand or collapse parts of a diagram.
Show/Hide Subordinate Shapes

When working on a complicated OrgChart diagram, you can collapse all the subordinate shapes except those you wish to focus on. You can also specify the number of hierarchy levels retrieved from the data source, as well as the number of the nested levels that should be expanded when the diagram is generated.

Rulers and Dynamic Grid
Position shapes precisely.
Rulers and Dynamic Grid

Rulers help you position shapes precisely. When visible, rulers appear along the top and left side of the diagram. Markers in the ruler display the shapes's position when you move it.

To enhance drawing speed and efficiency, you can display a rectangular grid. The grid is dynamically changed during zooming. If you zoom in or out of your drawing, the grid spacing is adjusted automatically to be more appropriate for the new magnification.
