Prototype template rulers (such as clothing pattern rulers, curve rulers, etc.) are practical tools in clothing pattern making. They can help designers quickly draw standard lines, adjust the proportions of the pattern, and improve the accuracy of pattern making. The following are specific methods and steps to assist pattern making:
1. Draw basic prototypes
- Positioning key parts
Use the scale marks on the template ruler (such as neckline, armhole, waist joint, etc.) to quickly determine the key points of the prototype, for example:
- Shoulder slope: determine the natural shoulder line through the angle line on the ruler.
- Armhole depth: directly locate according to the scale scale on the ruler (such as B/6+7cm).
- Contour line drawing
Use the curve module on the ruler (such as armhole curve, neckline curve) to draw ergonomic and smooth lines to avoid hand-drawing deviation.
2. Adjust the pattern and grading
- Dart transfer
Use the rotation scale or dart mark on the ruler to assist in the movement of the dart position (such as waist dart to armhole dart).
- Scaling
Use the scaled plaid or parallel lines on the ruler to scale up/down the pattern (e.g., from size S to size M).
3. Special design aids
- Asymmetric design
Use the symmetry axis of the ruler to quickly mirror the other side of the pattern.
- Complex curves
For example, fishtail skirts, wavy necklines, etc., you can use a variable curve ruler to adjust the arc and copy it to the pattern.
4. Efficiency optimization tips
- Marking alignment points
Use the cutout symbol on the ruler to mark the seam alignment points directly.
- Quick correction
Compare the standard arc on the ruler with the hand-drawn line to check and correct the deviation (e.g., the matching degree between the armhole and the sleeve cap).
5. Notes
- Matching human body data: The default scale of the template ruler needs to be adjusted according to the actual measurement data.
- Tool combination: Use with a ruler and a protractor to make up for the limitations of the template ruler (e.g., right-angle drawing).
By using the prototype template ruler properly, the plate maker can reduce the time of repeated measurements and ensure the standardization of the pattern, which is especially suitable for beginners or when rapid publication is required. However, it should be noted that flexible adjustment is still the key and you cannot rely entirely on the template data.
