Pattern development, including drafting, draping, and computer-aided design (CAD)

Pattern Development

  • Pattern development is a crucial stage in designing and manufacturing textiles; it lays the blueprint for garment construction.

  • There are three main methods: manual drafting, draping, and computer-aided design (CAD).

Drafting

  • Drafting involves creating a flat pattern on paper using the measurements of the final garment.

  • The drafting method typically begins with a measurement set either from a person or a dress form.

  • A ‘block’ or ‘sloper’ pattern is created as a template with zero ease or design allowance.

  • Additional measurements and adjustments are added to the block pattern to create the different elements of a garment

  • Drafting requires a strong understandings of geometry and a keen attention to detail to ensure accurate measurements.

Draping

  • Draping is a more visual and creative way of pattern development. It involves pinning, folding and marking material on a dress form.

  • This method allows the designer to see the overall appearance and fit of the garment before it is constructed.

  • Draping can be used to experiment with different fabrics and designs, or to create garments with complex shapes and structures.

  • It is crucial to have a good understanding of fabric properties and behaviour to effectively drape a pattern.

Computer-aided design (CAD)

  • CAD is a modern method of pattern development, offering efficiency and precision.

  • CAD systems utilise digital tools to create, modify, analyse, and optimise designs.

  • This method can effectively streamline the entire garment production process: from initial sketching, pattern drafting to grading and marker making.

  • CAD allows for easy adjustments and amendments in the pattern, and also saves the created designs for future use or modification.

  • Crucial advantage of CAD include its accuracy, speed and the ability to create a 3D visualisation of the final garment.

Remember, a good understanding of these methods will aid in pattern and design creation. Choose the best method based on the design elements, fabric chosen and manufacturing process.
