Custom Hatch with Question Marks

chrismb11 — Mon, 27 Apr 2020 13:44:28 GMT

I need a custom hatch that will fill an area with question marks. I tried manipulating an existing PAT file created for the number 2, but I can't seem to get it. Does anyone have a PAT that will reflect question marks or see the issue with below. Thanks

@chrismb11 it looks pattern works for me .

please see

there are something you can check

make sure you added the pattern definition to the right .pat file and it can be searched by autocad application

eg: C:\Users\USERNAME\AppData\Roaming\Autodesk\AutoCAD 2019\R23.0\enu\Support\acadiso.pat

some time ,the pattern has already here ,but it can not be visible due to the wrong scale. so you also can try to adjust the scale of your hatch.

hope it helps

I suspect that could be written with fewer lines [the last 5 could likely be combined into one lineset], but in any case, just to fix it....

Try this:

-90, 54,54, 0,100, 1,-99
123.6900711, 54,54, 83.2050323,-55.4700203, 3.6055512,-356.949585
123.6900711, 154,54, 83.2050323,-55.4700203, 3.6055512,-356.949585
180, 52,57, 0,100, 3,-97
225, 49,57, -70.7106705,-70.7106857, 2.8284271,-138.592926
90, 50,45.595, 0,100, 3,-97
90, 50,42, 0,100, 1,-99 ;; changed origin from 50,105, changed pen-up from -97
243.434967, 54,53, -89.4427338,-44.7213364, 2.236068,-221.3707275
218.6598053, 53,51, -62.4695015,-78.08688354, 4,-636.3122731

;; changed origin from 105.5,93, changed pen-up from -633.9093018; correspondingly on following
218.6598053, 153,51, -62.4695015,-78.08688354, 4,-636.3122731
218.6598053, 253,51, -62.4695015,-78.08688354, 4,-636.3122731
218.6598053, 353,51, -62.4695015,-78.08688354, 4,-636.3122731
218.6598053, 453,51, -62.4695015,-78.08688354, 4,-636.3122731

The first blue number [42] is arbitrary -- change it if you want the "dot" closer to or farther from the squiggle part.

Remove the ;; commentary if you like.

[And I would change the name of the pattern, since it's not about 2's any more.]

Greatly appreciate the help. Is there a easy adjustment to double the characters to make more dense?

Again, thanks for the help and fast response.

Certainly, but not right now.... Maybe later today I'll look at that.

Perfect. Really appreciate it. Exactly what I needed.

With a slight change in the shape of the squiggle part, it becomes much simpler to define:

90, 0,-7, 50,50, 1,-2,2,-95
45, 0,-2, 0,70.71067812, 5.65685425,-65.05382387
90, 4,2, 50,50, 3,-97
135, 4,5, 0,70.71067812, 2.82842712,-67.88225099
180, 2,7, 50,50, 3,-97
225, -1,7, 0,70.71067812, 2.82842712,-67.88225099

And note the first line, which includes both the "dot" and the bottom vertical piece of the "squiggle" in one lineset definition. The Hatchkit version didn't realize that possibility, and I have seen many pattern definitions produced by it that have similar overkill. Even without changing the shape of the squiggle, I'm sure a definition could be more concise.

Excellent option. Thanks for the help.

The following is all you need. I changed offsets and pen-down/pen-up numbers to double the density, and fine-tuned some of the numbers for greater accuracy farther from the origin, and I eliminated redundant lines that the original also had, which are not needed when appropriate offsets and pen numbers will cover all of those at the same angle in the same position within the shape, nor with the collinear pieces. I didn't move lineset origin points closer to the pattern origin, but I did eliminate the little misfit "shoulder" overhang in the original.
