1. Material: It is typically made of a thin strip of lead or metal enclosed within a rubber or plastic sheath. This combination allows it to be flexible and easily shaped to the desired curve while maintaining stability.

2. Flexibility: The ruler can be bent and molded into various curves and shapes, and it will hold the shape until you decide to change it. This makes it a handy tool for drawing irregular or organic shapes.

3. Accuracy: It is used to create smooth, freehand curves that are difficult to achieve with fixed rulers or templates. This is essential for creating accurate drawings, particularly in technical and engineering applications.

4. Applications: Architects use flexible curves for creating curves in building designs, while engineers use them in mechanical design and other technical drawings. Artists often use them for drawing smooth curves in illustrations and graphic design work.

5. Drawing and Drafting: To use a flexible curve ruler, you place it on your drawing surface and bend it to match the curve you want to draw. Then, you can trace along the curve with a pencil, pen, or other drawing tool.

6. Available Sizes: These rulers come in various lengths, typically ranging from about 12 inches (30 cm) to 24 inches (60 cm), although longer versions may also be available.
