How to make custom hatch pattern in AutoCAD

Usually, to fill an space with a pattern hatches are used and there are many ready-made hatch patterns out there in AutoCAD however if you need to use your personal custom hatch pattern then you’ll be able to make it using a kind of straightforward code and in addition using an categorical device referred to as Superhatch.

On this article, I’ve explained each the methods in detail together with the process of transferring hatch pattern from one drawing to different.

Making hatches utilizing Superhatch is pretty straightforward and it does not want any type of code however you gained’t give you the option to transfer these custom hatches from one drawing to other which could be very limiting for a lot of the makes use of.

Then again, you’ll be able to simply switch hatches made with “hatch code”. To begin with, I’ll clarify making custom hatch pattern utilizing hatch code than about Superhatch software.

However should you don’t feel like reading the article you possibly can watch this video as properly which explains each the strategies.

Now the article continues.

Making Hatches utilizing “Hatch Code”

In this case, I will make this easy stair sort hatch pattern utilizing the “hatch code”.

So, to do that open Notepad (or another Unicode textual content editor if you need) and sort the next strains.

*TESTHATCH, Our check hatch with the staircase effect

0, zero,0, .2,.2, .2,-.2

90, .2,zero, .2,.2, .2,-.2

These strains will truly make the pattern which you see in the image above. After adding these strains in the textual content editor reserve it as a PAT file utilizing the identical identify defined in line 1 of this code.

In this case, you want to save the file as TESTHATCH.PAT, in the event you hold a special identify for the PAT file then the custom hatch pattern won’t work.

Let’s deconstruct these strains and to simplify this I have coloured the horizontal phase Pink and vertical one Inexperienced.

Now, let’s transfer back to the Hatch code which I just showed you above. The entire code has three strains with characters in each line separated with commas.

Each set of character inside comma has its own which means and all of those strains will add up to make the entire pattern. In this case, line 1 will decide identify and outline of hatch pattern, line 2 is for the horizontal phase of the hatch and line 3 is for the vertical phase.

Line 1: *TESTHATCH, Our check hatch with the staircase impact

On this line, the hatch code begins with a star signal followed by the identify of the hatch in uppercase. Then we’ve an outline for the hatch separated by a comma. So, primarily the hatch code ought to start with star sign then identify after which description all separated by a comma.

Line 2: zero, zero,0, .2,.2, .2,-.2

The line 2 is for the Purple line shown in this image.

Right here the first character 0 is for the angle which is 0 degrees which makes the road horizontal.

The second and third characters zero,zero are coordinates of the starting points of the horizontal line. On this case 0,zero is just not the absolute coordinate moderately its an origin assigned by hatch pattern for that exact pattern only.

The subsequent characters .2,.2 are for the start line on the subsequent set of the horizontal line with respect to the origin set for the first point.

The last two characters .2,-.2 are for the size of the road phase and hole length. The size of the phase is proven as .2 (constructive worth) and the gap is proven as -.2 (unfavourable worth) unit.

In case you are accustomed to making custom linetypes in AutoCAD then you’ll discover that this hatch code is sort of comparable to the linetype code for custom AutoCAD linetypes.

Line 3: 90, .2,zero, .2,.2, .2,-.2

The road three is for the green strains as shown in the picture under.

Right here the first character 90 is for the angle of the road which you’ll be able to see that, in this case, is vertical or at an angle of 90 degrees.

The second set of characters .2,0 are the coordinates of the start line of the first inexperienced line in the direction of lower left column and this coordinate point is with respect to the origin defined in line 2 of the hatch code, which for this case is the start line of the first pink line as proven in the image 3 above.

The third set of characters .2,.2 is as soon as again the offset worth of 90-degree line along X and Y axis or the displacement of the subsequent set of the vertical line alongside X and Y axis and its in this case again 0.2 models.

The last set of characters .2,-.2 are as soon as again the size of the vertical phase and the hole of the phase. The constructive value is for the size and destructive value is for the hole.

Getting the entire hatch pattern

As you just now saw that every line has its personal position in making the entire hatch pattern and you may add even more strains in this code that may ultimately add up to make an entire pattern. So, in a nutshell, every line of the hatch pattern code will make a set of similar parallel strains which end up giving a pattern shape.

There are also some finer particulars associated to making hatch pattern that you simply need to care for like you need to add at the least one clean line on the end of the hatch code in order to make the hatch code work. Also, you need to make sure that the hatch pattern identify defined in the code and identify of PAT file must be the identical. Extra may be seen in this Autodesk information community article.

Utilizing and Transferring Hatch Patterns

To use this hatch pattern in the drawing you need to copy the PAT file in the help folder. To seek out the situation of help folder sort OP and press enter. Then select the file tab and increase the “Support File Search Patch” tree and there you will notice the situation of the help folder.

I have marked the help folder for my PC in this image in the pink box.

To switch the hatch pattern to different PC all you want to do is just copy paste this custom PAT file in the help folder of PC where you want it to switch.

Alternatively, you can too add a location to this listing of help information after which save all of your custom hatch patterns in that folder. This technique has been defined in the video above.

Making Hatches utilizing Superhatch

Hatches work the best way that fonts do, as vector pictures. Beneath regular circumstances, you can’t add image information and determine them as a Hatch. As an alternative, it’s essential to make a textual content file with specific coding but with superhatch, you’ll be able to even make hatches with photographs.

Super Hatches, as the identify would suggest, permit you to go above and beyond when creating hatches. Within the SUPERHATCH command, there are 5 choices. We’ll find out how to use the primary three.

From Block Choice

We are going to make a Hatch Pattern from an AutoCAD block. This may be finished with any 2D block in AutoCAD.

Make a Pattern inside the circle that’s in our AutoCAD drawing. It can be any type of Pattern, I made one like this.

The subsequent step is to make a rectangle in which we’ll apply the hatch. For this next part, there are numerous steps involved, so pay shut attention.

First, sort BLOCK in the Command Line, and hit ENTER to open up the Block Window. Within the Block Window, Click on “Pick point” and then click the bottom-most level of our circle marked in the pink oval in the picture under.

Where it says “Name” in the Block Window, give your Block a name. It can be something you like, as long as you possibly can keep in mind it. I’m naming mine “Pattern for Hatch Tutorial”.

Subsequent, in the Block Window, Click on “Select objects” and highlight everything of our circle pattern.

Following that, you’ll be able to click on OK on the backside of the Window to close it.

These steps have been pretty commonplace. We have been simply making our pattern into Block. The following steps are the place we make our Block right into a Hatch.

If in case you have Categorical Tools, you possibly can go to the Categorical Tools Tab in the Ribbon and click the Super Hatch icon. For those who don’t have Categorical Tools, you’ll be able to simply sort SUPERHATCH as an alternative in the Command line, after which hit ENTER. Categorical tools or SUPERHATCH command is just not out there in AutoCAD LT.

In the Tremendous Hatch Window, Click on “Block…”. After that, Click on “OK” in the subsequent Window.

The subsequent step is to click anyplace inside the now empty rectangle at the middle of our drawing.

The command dialogue will ask about x-scale. Sort 0.5 and hit ENTER. Hit ENTER once once more to apply the identical scale to the Y-axis. Hit ENTER repeatedly until you get to the part about “Specify Block [Extents]”

Inside our rectangle shall be a smaller version of our Block, with a magenta rectangle bordering that block. Click the bottom-left point of that magenta rectangle. After that, click on the top-right level of that magenta rectangle. Then, hit ENTER and click on again anyplace contained in the rectangle where you want to make the hatch and hit ENTER one remaining time.

Your remaining outcome ought to look one thing along these strains.

From Image Choice

Making a picture into a Hatch isn’t all the time so sensible, but when mandatory, it is potential.

We can be utilizing this image wrinkled paper image. You’ll be able to download this picture by right-clicking and choosing “save image as” choice from the contextual menu.

Reserve it to your pc as WrinkledPaper.jpg.

Again in AutoCAD, make a rectangle with a line passing vertically via its midpoint. We shall be Super Hatching that rectangle with our image.

Load up the SUPERHATCH Command and Select “Image..” from the Tremendous Hatch Window.

Within the Windows Explorer Window that pops up, find the picture you saved of the Wrinkled paper, select it, and click “Open”.

Click “OK” in the following window.

Following that, the AutoCAD command line will ask you to select an insertion point. Click the bottom-left corner of the left rectangle in our drawing.

Subsequent, AutoCAD will want you to decide a Scale Issue for the insertion. It often takes a couple tries to work out the perfect measurement. By means of trial and error, I discovered that it was greatest to use a scale issue of 50.zero in my case, in your case it might be totally different.

Sort 50.0 in the command line and press ENTER. Hit ENTER once once more to agree that you simply find the location acceptable. Next, the dialogue will ask you to decide inner factors. Click the border of the rectangle. Half can be chosen. It is going to be highlighted. Your rectangle should look comparable to Determine under.

Hit ENTER one remaining time. Your rectangle ought to now appear to be Figure under.

What is basically special about Picture Hatches is you’ll be able to individually select every tile and delete it or resize it in case you like.

Updating a Hatch

Create an atypical Hatch on the on the other of the rectangle and then delete the vertical line separating the Image Hatch from the Pattern Hatch. Now, when you delete Image Tiles bordering the Pattern Hatch, after which Hatch the empty areas, it is going to update our previous Pattern Hatch to embody the brand new space.

You will notice white strains bordering the Image Tiles. If you need to eliminate these, doing so is sort of simple. Simply sort IMGFRAME into the Command Line and hit ENTER. Then sort zero, and again, hit ENTER.

The image hooked up in this hatch will behave like an Xref and for those who delete the original picture then hatch may even disappear leaving only rectangular boundaries as an alternative of picture grids.

From Xref Attach

Xrefs are Exterior References. To make an External Reference right into a Hatch, you simply make a Hatch design in one other drawing and then save the drawing. Following that, use the SUPERHATCH command, decide “Xref Attach…” from the Super Hatch Window. Within the Home windows Explorer Window that seems, decide the Hatch drawing you created. All you’ve gotten to do after that’s decide an insertion level and hit ENTER.

Conclusion

As you simply noticed that AutoCAD is sort of flexible to permit you to make hatch pattern instantly utilizing Superhatch and in addition with hatch code. Both the methods can be used to make hatches but the hatch code provides you extra flexibility because the patterns could be transferred simply and could be custom-made by altering just some strains in the hatch code.

Which of the methods did you employ typically or planning to use for making custom hatches? Don’t overlook to let me know in the feedback under.
