Extract Hatch Patterns

Sometimes you have a nice AutoCAD Hatch Pattern already in a drawing and you want to use them in other dwgs, but you don’t have the hatch pattern file. The result of using HACEXT will be the ‘pat’ file that can then be used in any other AutoCAD dwg.

Loading HACEXT

Load the application using the pull-down menu: Tools -> Load Application – select the file hacext.vlx

At the Command prompt, you can load the application using the AutoLISP function load:

       Command: (load ”hacext”)

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

Running HACEXT

At the Command: prompt, type hext. AutoCAD will ask you to select an object. The selected object must be a hatch. For example, if you have an co-workers drawing and you want to capture the stone facing pattern, run HACEXT to capture the existing pattern to easily add it to your library.

After selecting the desired hatch pattern wait few seconds, until the Command prompt will appear again. Now you have on your disk a file containing the hatch pattern.

The name of the file is the pattern name, with an “x” at the end (this avoid overwriting an existing hatch file).

The extension is “pat”, and the location is the directory listed first in the Support File Search Path (in the pull-down menu: Tools -> Options -> Files).

The new pattern appear in the list of the custom patterns when using the command HATCH or BHATCH.

Precision:

The precision of calculus is affected by the snap value. The default value is 0.05. As the snap value is smaller, it is necessary more time for processing. The maximum precision allowed is 0.001.

The result of hatching with the new pattern will appear like in the picture snapshot to the right.
