Hatch Pattern Compatibility

The good news is that the hatch pattern format hasn't changed since it was first introduced years ago. Any hatch pattern you find should work with any previous or future version of AutoCAD!

2005 Hatch Pattern Snaps

There has been a change in behavior in AutoCAD 2005 regarding the object snaps on its geometry. In previous releases osnaps would honor hatches, in 2005 they are ignored by default. To turn on the snap to hatch, access the OPTIONS dialog (Tools menu), go to the Drafting tab, and in the lower left you will find the toggle.

Also there is a command line system variable OSNAPHATCH, set to 0 for off (no snap), 1 for on (snap).

Adding Hatches

This procedure will walk through the process of adding a hatch pattern to your system, all the way through the final step of adding the pattern to the AutoCAD BHATCH dialog.

Important Note: Autodesk changed the behavior of the BHATCH dialog beginning in version 2000. As a result of this change, the BHATCH dialog completely ignores the hatch slide contained in the slide libary. It choose instead to create a very small (nearing unreadable) swatch on the fly, which takes a significant amount of time if you have hundreds of patterns. As such this procedure may not be applicable unless you intend to compile your hatchs into a IMAGE menu.

Preparing the Pattern: The first step is to obtain or create a hatch pattern that you would like to add. For terms of discussion we will use the GRAVEL.PAT found floating on the web. I have no knowledge of the author. Note that this pattern does not have sufficient precision to properly display in large coordinate mapping, but should work well in most other applications. It has been reproduced here.

We could place this code into the file GRAVEL.PAT, place it into a search path, and refer to it at the HATCH prompt. However since our final goal is to have this pattern available in the BHATCH dialog, a little more work is required.

Adding the pattern: To add the pattern code to the ACAD.PAT file, it is first recommended that the existing ACAD.PAT (AutoCAD support directory) be backed up. In the event that something goes wrong we can restore without having to reinstall.

Open the original ACAD.PAT in a notepad or other ascii editor. It is a good idea to do a search to make sure that the pattern definition you are about to add does not already exist. One night at flumpty%27s 2 macro. If you do
