(Gradients are hardcoded and cannot be customized.) LINE 1: HEADER Each hatch pattern definition consists of at least two lines of text, a header that labels the pattern, followed by one or more lines of data that describe the pattern. pat files and are applied with the Hatch command. The pattern repeats itself, which is done by specifying an offset distance and an angle, as illustrated below: We look at both methods in this post.ĭespite seemingly complex, hatch patterns consist of the same three basic elements as linetypes: dashes, gaps, and dots. BricsCAD provides you with two ways to create custom hatch patterns: (a) simple patterns defined with the Hatch and -Hatch commands and (b) edit the default.pat file or write new. In this post, you will learn how to use and customize pattern hatches in BricsCAD ®.
