Custom hatch patterns

- [Instructor] Custom hatch patterns are similar…to custom line type definitions in many ways.…They're located in an external file,…they're editable within a standard text editor,…and they work off the premise…of the pen down for a positive number,…pen up for a negative number.…There are some distinct format differences, though.…Let's create a hatch pattern and notice the similarities,…as well as the distinctions.…So we're going to create a hatch pattern…that is an eight by eight tile paver offset.…

So the first line, like a line type definition,…is the name of the hatch pattern,…as well as the description of the hatch pattern.…Let's create our first line…of the hatch pattern definition.…What we have here is a definition of a line…that is infinite in length.…The rotation is zero,…so the line is horizontal.…The line begins at zero comma zero.…and the line offsets, or the delta,…is eight units vertical.…

So every eight units, this same line pattern will duplicate.…Let's create our next line for the hatch pattern.…So our next line is vertical,…
