Custom Pattern Files
A pattern file is a text file that contains definitions for model or drafting patterns in a project. The file must
be saved with a PAT extension. For information on using a custom pattern file, follow the procedure in
Creating a Custom Fill Pattern on page 462.
Pattern File Format
Units:
;%UNITS=[value]
Header:
*pattern-name, [optional description]
Type declaration:
;%TYPE=MODEL
Pattern descriptors:
angle, x-origin, y-origin, shift, spacing
Creating a Custom Pattern
This example shows how to create a pattern of octagons and squares in the pattern file. You can use the
description here to create other patterns.
The completed pattern contains octagons that are 8 inches at their widest point; both the octagon and the
square are 3 5/16 inches on a side.
1 Open a text editor, such as Notepad, to begin creating the pattern file.
2 On the first line, enter the header in this format: *Concrete Paver .
3 On the next line, enter the type declaration: ;%TYPE=MODEL .
The first value for a pattern descriptor is the angle at which the pen line is drawn. For example,
a 0 angle indicates the line is horizontally straight; 90 angle indicates the line is drawn vertically
straight.
4 Create the first pattern descriptor, using the following values:
■
Angle: 0
This value is the angle at which the pen line is drawn. For example, a 0 angle indicates the
line is horizontally straight; a 90 angle indicates the line is drawn vertically straight.
■ Origin: 0, 0
These values are the x-origin and y-origin, which indicate the start point.
■ Shift: 5.656, 5.656
These values establish the x-shift and y-shift, which is the x and y distance between the start
of any pass and the start of the next pass.

Pen down: 3.3125
■ Pen up: -8
