They are composed of two-dimensional boundary loops that define areas which can be filled with line patterns or color gradients. The loops of each hatch are closed, simple, continuous, and are not self-intersecting except at their endpoints. Since loops are closed lines that are considered area boundaries, they are essentially polygons. The AutoCAD Reader creates features with varied geometry depending on the geometry of the loops that compose them. Features created may be of polygon, donut, or aggregate geometry, where the aggregates may contain either donuts and polygons or just ordered polygons depending on the usage of the Preserve Complex Hatches and MPolygons reader parameter.
Don’t let hatch objects obscure your linework
How to make custom hatch pattern in AutoCAD How to make custom hatch pattern in AutoCAD View Larger Image Generally, to fill an area with a pattern hatches are used and there are plenty of ready-made hatch patterns available in AutoCAD but if you want to use your own custom hatch pattern then you can make it using a type of simple code and also using an express tool called Superhatch.
In this article, I have explained both the methods in detail including the process of transferring hatch pattern from one drawing to other. To begin with, I will explain making custom hatch pattern using hatch code than about Superhatch tool. Now the article continues. So, to do this open Notepad or any other Unicode text editor if you want and type the following lines. After adding these lines in the text editor save it as a PAT file using the same name defined in line 1 of this code.
The complete code has three lines with characters in each line separated with commas. Every set of character inside comma has its own meaning and all of these lines will add up to make the complete pattern. In this case, line 1 will determine name and description of hatch pattern, line 2 is for the horizontal segment of the hatch and line 3 is for the vertical segment. Line 1: Then we have a description for the hatch separated by a comma.
So, essentially the hatch code should start with star sign then name and then description all separated by a comma. Line 2: Here the first character 0 is for the angle which is 0 degrees which makes the line horizontal. The second and third characters 0,0 are coordinates of the starting points of the horizontal line. In this case 0,0 is not the absolute coordinate rather its an origin assigned by hatch pattern for that particular pattern only.
The next characters. The last two characters. The length of the segment is shown as. If you are familiar with making custom linetypes in AutoCAD then you will notice that this hatch code is quite similar to the linetype code for custom AutoCAD linetypes. Line 3: Here the first character 90 is for the angle of the line which you can see that, in this case, is vertical or at an angle of 90 degrees.
The second set of characters. The third set of characters. The last set of characters. The positive value is for the length and negative value is for the gap. Getting the complete hatch pattern As you just now saw that each line has its own role in making the complete hatch pattern and you can add even more lines in this code that will eventually add up to make a complete pattern.
So, in a nutshell, each line of the hatch pattern code will make a set of similar parallel lines which end up giving a pattern shape. There are also some finer details related to making hatch pattern that you need to take care of like you need to add at least one blank line at the end of the hatch code in order to make the hatch code work. Also, you need to ensure that the hatch pattern name defined in the code and name of PAT file should be the same. More can be seen in this Autodesk knowledge network article.
To find the location of support folder type OP and press enter. I have marked the support folder for my PC in this image in the red box. To transfer the hatch pattern to other PC all you need to do is just copy paste this custom PAT file in the support folder of PC where you want it to transfer. Alternatively, you can also add a location to this list of support files and then save all your custom hatch patterns in that folder. This method has been explained in the video above.
Making Hatches using Superhatch Hatches work the way that fonts do, as vector images. Under normal circumstances, you cannot upload image files and identify them as a Hatch. Instead, you must make a text file with specific coding but with superhatch, you can even make hatches with images. Super Hatches, as the name would imply, allow you to go above and beyond when creating hatches. We will learn how to use the first three.
It can be any sort of Pattern, I made one like this. The next step is to make a rectangle in which we will apply the hatch. For this next part, there are a lot of steps involved, so pay close attention.
It can be anything you like, as long as you can remember it. Following that, you can click OK at the bottom of the Window to close it.
Those steps were pretty standard. We were just making our pattern into Block. The following steps are where we make our Block into a Hatch. The next step is to click anywhere within the now empty rectangle at the center of our drawing. The command dialogue will ask about x-scale.
Type 0. Click the bottom-left point of that magenta rectangle. After that, click the top-right point of that magenta rectangle. Your final result should look something along these lines. We will be using this image wrinkled paper image. Save it to your computer as WrinkledPaper. Back in AutoCAD, make a rectangle with a line passing vertically through its midpoint.
We will be Super Hatching that rectangle with our image. 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. It usually takes a couple tries to figure out the best size. Through trial and error, I found that it was best to use a scale factor of Type Next, the dialogue will ask you to pick internal points.
Click the border of the rectangle. Half will be selected. It will be highlighted. Your rectangle should look similar to Figure below. Your rectangle should now look like Figure below. What is really special about Image Hatches is you can individually select each tile and delete it or resize it if you like. Updating a Hatch Create an ordinary Hatch on the on the opposite of the rectangle and then delete the vertical line separating the Image Hatch from the Pattern Hatch.
Now, if you delete Image Tiles bordering the Pattern Hatch, and then Hatch the empty spaces, it will update our previous Pattern Hatch to encompass the new area. You will notice white lines bordering the Image Tiles. If you want to get rid of these, doing so is quite simple. The image attached in this hatch will behave like an Xref and if you delete the original image then hatch will also disappear leaving only rectangular boundaries instead of image grids.
To make an External Reference into a Hatch, you simply make a Hatch design in another drawing and then save the drawing. In the Windows Explorer Window that appears, pick the Hatch drawing you created.
Conclusion As you just saw that AutoCAD is quite flexible to allow you to make hatch pattern directly using Superhatch and also with hatch code. Both the methods can be used to make hatches but the hatch code offers you more flexibility as the patterns can be transferred easily and can be customized by changing just a few lines in the hatch code.
