Sampling is a process of making a product proto-type prior to starting bulk production. The same process is applied to garment sampling. In mass garment manufacturing, where apparel brands source garments in bulk quantity, sample making is an essential step before placing the bulk order. The objective of the sampling is to eliminate the risk of making a wrong purchase of raw material, making mistake in bulk manufacturing that is not accepted by the buyer. Brands also would like the situation where they can't feed the retail shops or can't deliver the garment to their potential customers.

Sampling process covers garment fit checking, fabric and trims quality checking, approval value-added processes, and approval of complete finished garment. Most of the buyers have a standard requirement for garment sampling for the product for sourcing the bulk garment - what types of samples they need; when they need it; and how many pieces are needed for each sample type.


CAD is a set of software tools compiled in a computer application to assists product designer in creating a virtual representation of the artefacts they are designing. It helps in giving dimension to any design, experimenting changes on it, configuring the design according to needs, archiving the design, exchanging of data and information related to the design between teams and organization, adding progress of the designs for future analysis, assisting tool for product manufacturing by means of a computer system which may include both hardware and software.

The long and cumbersome process of designing has now been converted to a mere simple process on a computer system. CAD can be used to design curves and figures in two-dimensional (2D) space; curves, surfaces, and solids in three-dimensional (3D) space. Even a 2D design can be converted to 3D for a better representation of the design.
