Royalty FREE AutoCAD hatch patterns, including wood, stone, stonework patterns and seamless textures. Creating Hatch Patterns by Kenny Ramage You want to what?! Create a hatch pattern? Crikey, you're brave. Honestly, though, simple hatch patterns are quite easy to create. It's the complicated ones that take time, effort, a good understanding of how to create hatches and linetypes, some knowledge of geometry and quite a bit of imagination. Before proceeding with this tutorial, I would strongly recommend that you read my tutorial on. Linetypes are used extensively throughout hatch patterns and a good understanding is a pre-requisite. ![]() Let's take a look at a simple hatch pattern first. The same principal applies to even the most complicated hatch pattern so, as my Mum often says, 'Pay attention!' A hatch pattern definition is stored in a simple ASCII text file with an extension of PAT. You can append a hatch pattern to an existing file if you wish, or you can store it in it's own file. If you store it in it's own file, the file name must match the name of the hatch pattern. We are going to create our own hatch definition or pattern file. Now add this on the next line: 0, 0,0, 0,0.5, 0.5,-0.25,0,-0.25,0,-0.25 This line describes a single drawing pass over the hatch pattern. In this example we are only using a single pass so we will only get one line. Save your file as 'Dashdot.pat'. If you loaded this hatch pattern and added it to your drawing, it would look like this: The syntax of each drawing line is as follows: Angle, X,Y Origin, Offset-x,Offset-y, Pen Command Pattern Let's look a bit closer at each field: 0, 0,0, 0,0.5, 0.5,-0.25,0,-0.25,0,-0.25 The first field, Angle, which in our case is '0', determines the angle at which the line is to be drawn. In our case it will be drawn horizontally. Don't confuse this with the angle of the hatch pattern which is controlled by the AutoCAD Hatch command. Look at a hatch pattern as a successive series of lines that are drawn from left to right, then from down to up. 0, 0,0, 0,0.5, 0.5,-0.25,0,-0.25,0,-0.25 The second field is the X,Y Origin. This controls the starting point of the line segment. This is not an AutoCAD co-ordinate, but rather a relative distance from the current Snap base point of the drawing. All hatch patterns have a point of origin. Since this point of origin is the same throughout, you're assured that the patterns will line up. 0, 0,0, 0,0.5, 0.5,-0.25,0,-0.25,0,-0.25 The third field is the X-Offset and Y-offset values. 0 is the X-Offset and 0.5 is the Y-Offset. The hatch pattern will begin at an arbitrary origin and proceed to draw a group from left to right, then advance upward in the Y direction. 0,0.5 means that each successive line in the pattern will move to the right 0 units and up by 0.5 units.

The offset is relative to the initial angle given in the line, so that angle forms the X axis for the offset. The Y value Offset is quite easy to understand - it gives you the spacing between the lines.
