In those cases, while you could define separate lines and repeat them at the overall repeat, it is more efficient to define one line at the smaller, even fraction repeat (in the hypothetical example here, one line at 8" rather than three lines at 24"). How to install custom hatch patterns in AutoCAD AutoCAD Added PAT-files will cause hatches to be listed under the User Defined or Custom hatch menu within AutoCAD. The exception would be if within the overall larger repeat (say at 24"), there is a set of lines that repeats at some even fraction of the overall pattern (say 8").

Then you get a line at 41", but you do not get a line at 29".įor parallel line patterns like this, once you have the lines for one repeat defined, the offsets for all of them will be for the total distance of the pattern repeat.

If you jump 17" from the second line, you get a line at 24", but you already have a line there from the first line, on its second repeat, so you have two, coincidental lines there. The fourth pair of lines starts at 36", with lines at 36" and 41". The third pair of lines starts at 24", with lines at 24" and 29". The second pair of lines is offset 12" from the first pair, with lines at 12" and 17". So the first pair of lines starts at 0", with lines at 0" and 5". The pattern repeats every 12", with two lines in every repeat: one at +0" and one at +5" (since the first gap is 5").

You want lines spaced at alternating amounts of 5" and 7".
