Computer Aided Pattern Design
by Don McCunn Drawing Shapes
There are three shapes that can be used to create patterns: rectangles, circles and ellipses. Before you select a shape, first verify the Line Appearances are set to the desired color, style, and size. Then select a shape by clicking on the icon at the top left of the working area and click on the desired shape. Once you have selected a shape, you can draw multiple versions. To change from one type of shape to another, click on the Select icon. To discontinue drawing shapes, press the Esc key.
ContentsDrawing RectanglesAn important use of the rectangle tool is to create a Bounding Box for patterns. When patterns are placed inside the Bounding Box, the accuracy of the size of the patterns can be verified when they are printed or used by another program. For the patterns used for these instructions the Bounding Box is 8" by 10-1/2" (20.3 by 26.7 cm) so that the files can be printed using a standard desktop printer. |

Drawing CirclesA primary use of circles is to establish the Bust Circle for women's front patterns. The concept of the Bust Circle is that darts should not be sewn up to the Apex but set behind by the width of the Bust Circle. The size of the Bust Circle can be adjusted for different designs. |
