Diagram Connectors

Straight Connectors
Draw straight lines between connection points.
Straight Connectors
Straight connectors draw straight lines between connection points. As you move the shapes around, this connector stays straight.
Curved Connectors
Draw lines that can curve.

Right-Angle Connectors
A vertical and horizontal route with 90-degree bends that links shapes together.
Right-Angle Connectors
A vertical and horizontal route with 90-degree bends that links shapes together. The right-angle connector can be moved and twisted as shapes move.
Automatic Routing
You don't have to manually rearrange connectors and shapes.
Automatic Routing
The dynamic connector can route itself around shapes that get in the way and find the best point to connect to shapes. It will also jump over other connectors that cross it.
15 Arrow Types
Add arrows, points, or other line ends to a connector.
15 Arrow Types
Customize the way connector lines look by changing the arrow type, size and thickness.

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.
