Layout Planning (Marker making)
Computerized marker making systems helps in laying the pattern part together more economically than an
operator could hands. This ensures minimum wastage of fabric. On plain fabric this is relatively simple, but on
striped fabric also automatic matching is done by the computer. Pattern generated by marker making systems
can be directed to automated cutting machines which are operated without the help of human hands.(Fig 7)

Grading systems
After a sample size pattern has been put, it has to be graded up and down on size. Certain points on the
pattern are considered as” growth points” or places at which the pattern has to be increased or decreased to
accommodate changing body size. At each growth point, the operator indicates the grade rule of the computer.
The system will then automatically produce the pattern shapes in all the pre -specified sizes. Say if we define
pattern for size 30, it can be easily graded for size 32/34/36 and so on.(Fig 8)
Digitizing systems
Digitizer put original patterns into the computer for the use and storage. It can be done by defining the X; Y
coordinates of series of selected points around the pattern. These basic patterns can be manipulated with the
help of computer, for example in case of trousers, darts can be moved, pleated can be created. In this way new
designs can be created on screen from pre-existing pattern.(Fig 9)
