Shape recognition
The Lekh Diagram has a powerful shape recognition engine. You draw a rough shape using your finger and Lekh Diagram will recognize the shape.
Apart from recognizing shapes, it also recognizes connections between shapes. Draw two or more shapes and connect them in various ways (using touch gestures),
the Lekh Diagram will recognize those connections.

Customizing shapes by moving vertex and control points
The Lekh Diagram provides a powerful way of vertex/control point editing.
You can modify/customize any shape by moving vertex or control points of the shape.
The Lekh Diagram makes you to do this very preciously
using "vertex handle". This is how it works:
Tap on any shape to select
vertices and control points are shown as dots on the selected shape.
Tap on any vertex or control point to get the vertex handle
Now you can move the vertex by dragging the vertex handle placing your
finger anywhere on the vertex handle. This way the vertex/control point
that you are moving is not hidden behind your finger. So you can precisely
place the point anywhere.
Similarly you can customize other shapes too. For example you can customize bezier curve by moving their control points
Scaling and rotating shapes
Lekh Diagram lets you to scale and rotate shapes using multi touch gestures.
Aligning shapes
The Lekh Diagram gives you a powerful way of moving and aligning shapes.
It draws horizontal and vertical alignment line while you are moving any selected shape.
It displays the center and control points of other shapes while you are
dragging a shape. This makes you to easily align shapes.
Adding Text
Adding text inside you diagram is very easy using Lekh Diagram. You can add text two ways:
- Text as part of some shape like circle. For example if you add text on
a circle, the text will be drawn with that circle always. If you move the circle,
the text will automatically move.
- Floating text. You can add text anywhere, move them and rotate them
