HACI 1.4 - hatch pattern generator

HACI (V. 1.4) is an AutoLISP application for AutoCAD 2000 - 2010. It converts your drawing to hatch pattern, so you can easily convert your logos, symbols or patterns to hatches, which can be used in standard HATCH or BHATCH commands.

A library containing 96 hatch patterns is also available - Click here

Loading HACI

Load the application using the pull-down menu: Tools -> Load Application ? select the file haci.vlx. At the Command prompt, you can load the application using the AutoLISP function load:

Command: (load "haci")

The file haci.vlx must be in the AutoCAD support file search path.

Using HACI

Take any of your existing drawings, explode it to lines and fit it into a cell of 1x1 unit. Then launch the program using the command haci.

Enter a name and a description for your hatch pattern. Select the entities from the cell. HACI will process these entities according to the choosen precision.

Precision

The precision of calculus is affected by this value. The default value is 0.05. As the value is smaller, it is necessary more time for processing.

Limitations:

Only LINE entities are processed. Any 2D entity can be converted to LINEs. You must do this conversion before using HACI.
You have to use a 1x1 cell when draw the source. The source can also be smaller than 1x1 if the cells in the resulting hatch are independent.
If you use a pattern name that exists in the acad.pat file, the new definition will be ignored. You must first erase the old definition from the file.

What is the difference between the trial version and the full version?

Here is an example of a simple hatch pattern generated with both trial and full version of HACI:

As you can see, the two results are identical. But this is a simple pattern.
Now, see what we obtain when we want to create a more complex pattern:

The two results are very different. So, if you need to create hatch patterns like in the above image, you will need to buy the full version.
