The Rhombus tool lets you create a rhombus (a parallelogram with four equal sides) in three different ways
- Drag from one vertex to an opposite vertex, Mark it, drag to define the other sides
- Drag from the center to a vertex, Mark it, drag to define the other sides
- Drag from a vertex to the center, Mark it, drag to define the other sides
You can use the Drag Constraints button to control the horizontal or vertical orientation of the sides. Here’s an example.
Also, as with the other polygon tools, the Bezier Points button lets you specify the number of bezier points on each side.
