Based on the analysis of the image, here is a breakdown of the different curve rulers shown and their purposes:
The image displays three types of specialized rulers used in pattern making, particularly in fashion design. All are marked with both inches and centimeters for precise measurement.
1.
Hip Curve Ruler:
*
Appearance: This ruler has a long, gentle, single curve.
*
Purpose: As its name suggests, it is specifically designed to draw the natural curve of the human hip. It is an essential tool for creating accurate garment patterns, ensuring that pants, skirts, and dresses fit comfortably around the hips. Its simple, consistent curve makes it ideal for this specific task.
2.
French Curve Ruler:
*
Appearance: This ruler has a more complex, S-shaped design with multiple curves of varying radii.
*
Purpose: This is a versatile drafting tool used to draw a wide variety of smooth, flowing curves. It is not limited to one specific body part. Designers use it for shaping necklines, armholes, waistlines, and other curved seams where a gentle, aesthetically pleasing line is required. It allows for greater flexibility in design compared to the more specialized hip curve.
3.
Variform (Hip) Curve Ruler:
*
Appearance: This ruler has a long, sweeping curve that is more pronounced than the standard hip curve ruler.
*
Purpose: The term "Variform" suggests it is a variable or adaptable form. While it shares the "hip" designation with the first ruler, its shape implies it might be designed for a different type of hip curve or for drawing longer, more dramatic curves that extend beyond just the hip area. It could be used for creating flared skirts, wide pant legs, or other garments requiring a large, smooth arc.
In summary, these tools are all essential for pattern makers to create accurate and well-fitting garments by allowing them to draw precise, smooth curves that mimic the human body's contours. The Hip Curve Ruler is specialized for the hip, the French Curve Ruler is a general-purpose tool for many types of curves, and the Variform (Hip) Curve Ruler appears to be for larger or more varied hip-related curves.
