(Chicken hey!)Īs I said at the beginning, simple hatch patterns are quite easy toĬreate, but the complicated one's? Well, that's another story.A very good question was asked in in the comments section of the following post about creating custom hatches. I made the pattern at 0 andĩ0 degrees to avoid having to calculate the angles. Rotate the pattern to get the desired effect. This hatch will produce a pattern like this :Įven though I defined the pattern with 0 and 90 degree lines, you can Open a new file with Notepad and add this :Ĭlose the file and save it as "Vastrap.pat". The dashdot pattern was drawn using only one definition line, let's try Units, draw a third dot, lift the pen for 0.25 units and then repeat the Lift the pen for 0.25 units, draw another dot, lift the pen for 0.25 "Draw a line 0.5 units long, lift the pen for 0.25 units, draw a dot, The fourth and final group is the linetype definition or Offset by 0.5 to the right of the origin, creating a Would space the bricks upward by 1 unit, and every other line would be Each successive line ofīricks is offset to the right a little to create a pattern. But why would you want to offset the X value, and whatĮffect does that have? Think of a brick wall.
The Y value Offset is quite easy to understand - it gives you the spacingīetween the lines. So that angle forms the X axis for the offset. The offset is relative to the initial angle given in the line, 0,0.5 means that each successive line in the pattern will move to the The hatch pattern will begin atĪn arbitrary origin and proceed to draw a group from left to right, thenĪdvance upward in the Y direction. The third field is the X-Offset and Y-offset values. Origin is the same throughout, you're assured that the patterns will line All hatch patterns have a point of origin. This is not an AutoCAD co-ordinate,īut rather a relative distance from the current Snap base point of theĭrawing.

Successive series of lines that are drawn from left to right, then fromĭown to up. Is controlled by the AutoCAD Hatch command. Don't confuse this with the angle of the hatch pattern which The angle at which the line is to be drawn. The first field, Angle, which in our case is "0", determines The syntax of each drawing line is as follows : Angle, X,Y Origin, Offset-x,Offset-y, Pen Command Pattern This hatch pattern and added it to your drawing, it would look like this : In this example we are only using a single pass so we will only This line describes a single drawing pass over the hatch This is the name of our hatch pattern followed by a description of the pattern, separated by a comma (,). Open Notepad and add this line : *Dashdot, Dashes and dots Going to create our own hatch definition or pattern file. Own file, the file name must match the name of the hatch pattern. You wish, or you can store it in it's own file. You can append a hatch pattern to an existing file if The same principalĪpplies to even the most complicated hatch pattern so, as my Mum oftenĪ hatch pattern definition is stored in a simple ASCII text file withĪn extension of PAT. Let's take a look at a simple hatch pattern first. Linetypes are used extensively throughout hatch patterns and a good understanding is a pre-requisite.

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.īefore proceeding with this tutorial, I would strongly recommend that you read my tutorial on creating custom linetypes. Honestly, though, simple hatch patterns are quite easy to create. You want to what?! Create a hatch pattern? Crikey, you're brave.
