Can I get a hand creating a custom hatch?

Hi guys,

I have a pattern which I want to turn into a hatch, but I don't have knowhow to do it through CAD LT and I don't have full CAD available to me right now. Can I ask one of you lovely people to help turn the attached pattern into the hatch file?

Thanks!

How important is the specific angle of the ends? Because of the way linesets are defined in Hatch pattern definitions, it would be a lot easier if that could be tweaked [sharpened] just a little so that the red piece lies along a continuation of the green piece:

It would make this much difference:

If it makes sense to do that slight adjustment then go for it. Thanks!

Never mind -- it's not too far before an aligning edge occurs, so it's just a matter of a fairly long pen-up [negative-number] designation at the end of the diagonal lineset code lines. Try this [minimally tested]:

;; TEST.pat -- only ONE definition, called *TEST [copy to separate file with real pattern name] *TEST, description here if desired 90, 0,0, 11.75,1, 10.5,-13 231.34019175, 0,0, 14.79746394,0.31234752, 1.60078106,-73.63592873 308.65980825, 0,0, 14.79746394,-0.31234752, 1.60078106,-73.63592873

NOTE that while this code window doesn't allow it, if you put this in a .pat file of its own, it needs to end with a hard return / blank line, not just at the end of the code content. And the file name [not including the .pat filetype ending] must exactly match the pattern name defined in it.

Thanks for sending this, but it won't load the hatch. I can see it within my hatch drop down menu but wont' select it.

Put a blank space at the end of the definition.

Got it! I did have the space there but I had to remake the file and it ended up working.

Thanks!
