Activity 1

OptiTex™ produces a number of software packages. To familiarise yourself with the range of products select the following and summarise in point form their main features. Ensure you select More details for each one to get a better idea about each product.

Pattern design system (PDS)	provides pattern making tools data can be imported or exported to other CAD formats contains wide range of pattern making features such as darts, pleats, facings etc.
Grade	allows grading from scratch features a range of grading methods grades all features of a garment uses a library of grading rules grades notches suitable for difficult to grade items such as jackets, jeans and bra tops.
Mark	minimises fabric waste generates nested layouts quickly calculates optimum number of layers for cutting based on fabric thickness detects overlapped pieces before cutting.
Modulate	allows mass produced items to be modified for custom fit features a parametric model, where if one measurement is altered other measurements alter in parametric relation. all changes can be seen on the screen.
Match++	uses artificial intelligence and mathematical algorithms to position patterns on patterned fabrics such as plaids and stripes minimises fabric waste.

A three-dimensional draping tool is due for release soon. Describe its planned features. (You will need to scroll down the page.)

3D Draping Utilities will allow the pattern maker to visualise any changes made on a CAD system on a full-scale, three-dimensional human form in real time. The drape of the fabric used in the garment alters as the pattern maker makes changes on the flat pattern.

The Shadow pattern design system (PDS) is one product in the PolyNest system. Another is Autoscan. Explain the purpose of scanners in the sewn-goods industry.

Scanners are used to scan pattern pieces. The technology replaces digitising. Scanning is four to five times faster than digitising. Autoscan can also calculate the quantity of fabric required for a production run.
