The pattern making process is a key step in the development of apparel products. In this process, it is necessary to develop basic patterns, which serve as basis for the interpretation of different types of clothes.The purpose of this article is to present the automation of the basic patterns design process for women's pants construction. To do so, we used the Grasshopper parametric modeling program, which is a plugin of the Rhinoceros software. This system allows a parameterization of shapes, in a way that allows an adaptation of measurements of the geometry created.For the development of the tracing of the basic models of the women's pants, we used the steps indicated in the garment modeling method proposed by Romero (1995). The process in the Grasshopper uses mathematical operations and tools for drawing points, lines and curves.With the automation of the basic mold tracing, it is possible to adapt parameters according to the measurement chart of individual companies or customers.This adaptation also assists in the creation of several custom patterns, such as other types of pants and shorts, which can be interpreted through the basic pattern of pants. In a comparative analysis with the traditional method, the moldsgenerated in the Grasshopper obtained high fidelity in comparison to the tracing done manually, which allows the development of the molds without loss of quality. In this context, this project also aims to collaborate in the construction of a set of basic patterns that support the development of custom clothing.

The present study is divided in two constructive ways: conversion of volumetric bodies constituted by polygonal surfaces (quads) into surfaces NURBS and conformation of patterns or other polygonal entities on such volumetric bodies. There are numerous cases where the target topology cannot be converted to a single and unique NURBS surface, a procedure that would make the task of volumetric transposition easier and which would already be solved by the use of ready made parametric modeling tools. To carry out this article's tasks, generative modeling systems and associative parametrization strategies were adopted. The knowledge for the construction of the systems used in the present research can be used in different fields that have, as a paradigm, the design creativity as one of its beacons, such as Visual Arts, Architecture and Design. The present work aims to make use of digital manufacturing through laser cutting, 3D printing or CNC milling technologies, at the same time expanding strategies.
