General information

Sewist is a state-of-art pattern design system, that allows the use of a vast set of anthropometric measurements to get unparalleled fit of garments. To create a pattern, designers describe the sequence of drafting steps using proprietary pattern programming language.

Designer account

Designer account lets you access the pattern scripts created by you and other users, the pattern files, size measurements and documentation.

Pattern code

Pattern code is written in English letters using size constants, functions, variables and string expressions. You may use other encodings in string expressions, that are in quotation marks.

Variables

You can create your own variables and refer to them in the code. These can be numeric variables, names of objects, names of compounds of objects (path), names of pattern blocks.

Axes of coordinates

The X-axis goes from left to the right and Y-axis is turned downwards. Zero point is in the upper left corner of the pattern window.

Angles

In Sewist CAD, 0 degrees goes 3 o'clock, 90 degrees to 6 o'clock, 180 degrees to 9 o'clock and 270 degrees to 12 o'clock.

Size measurements

Using abstract reference to sizes (sz constants) enables you to create a single pattern code that will work across sizes with pinpoint accuracy. It allows the software to redraft patterns automatically for individual sizes based on a new set of size measurements, and it saves time on grading and ensures a great fit.

Mathematical functions and frequently used formulas

For basic mathematical operations, you can use the following signs: + (addition), - (subtraction), * (multiplication) and / (division). Just as usual, you can place parts of equation into brackets if you want certain actions to be done first, e.g. (a+b)*(c/d) etc.

Functions overview

Sewist Pattern Designer is based on various functions, that allow a pattern drafter to place points, connect them with lines, curves and arcs, rotate and move various objects, and basically repeat the flat pattern drafting process in an algorithm.
