Generate automatically hatch patterns from your AutoCAD drawings

HGEN (V2006 upd 4/2005) is an ARX application for AutoCAD 2000/2000i/2002 or 2004/2005/2006 (or MAP or Mechanical/Architectural Desktop) by CAD Studio (former Xanadu). It converts your AutoCAD drawing to hatch pattern (.PAT definitions) so you can easily convert your logos, symbols or patterns to hatches which can be used in standard _HATCH or _BHATCH commands in AutoCAD (or Desktops) or in Autodesk Revit. Creating hatch patterns has never been easier.

System requirements

HGEN requires AutoCAD 2000/2000i/2002 or 2004/2005/2006 (or MAP or Mech/Arch/Land Desktop) running on Windows 2000/XP.

Usage

Take any of your existing drawings. Explode it to simple entities (if neccessary - e.g. uses blocks; you can explode any 2D entity to lines). HGEN can scale the source drawing and can approximate curved entities to lines (AutoCAD hatch pattern definitions do not support arcs by default). HGEN converts and writes selected entities of your drawing to a .PAT definition (you can even append to ACAD.PAT) which can be subsequently used in _HATCH or _BHATCH commands. All .PAT files generated by HGEN can be also used in Autodesk Revit as model or drafting patterns.

Please note that the resulting PAT patern file is written in the current directory by default - it may be necessary to move it to your AutoCAD support folder.

Known limitations

  • Currently only LINE, PLINE, LWPOLYLINE, SPLINE, ARC, ELLIPSE and CIRCLE entities are processed (everything can be converted to them)
  • Currently you have to specify the 'unit' square cell (doesn't need to be 1x1, HGEN supports rescaling)
  • Only the first 65500 selected entities are processed

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. If you do not care about the order that your pattern appears in the BHATCH list, then simply paste the contents of the pattern definition at the end of the file. If you would like to maintain alphabetical order, carefully find the appropriate position in the middle of the list and insert your pattern there.

Be sure to save the ACAD.PAT file (ascii text only).

Preparing a slide: The next step is to prepare a slide representing the appearance of the pattern definition. The following steps can be used to create a hatch representation in R14. For users other than R14, you may need to generate a polyline (with the same coordinates), hatch the polyline, then erase the polyline.

Command: HATCH
Enter pattern name or [?/Solid/User defined] <ANSI31>: GRAVEL
Scale for pattern <1.0000>: 5
Angle for pattern <0>: <ENTER>
Select hatch boundaries or press ENTER for direct hatch option,
Select objects: <ENTER>
Retain polyline? <N> <ENTER>
From point: 0,0
Arc/Close/Length/Undo/<Next point>: 16,0
Arc/Close/Length/Undo/<Next point>: 16,10
Arc/Close/Length/Undo/<Next point>: 0,10
Arc/Close/Length/Undo/<Next point>: C
From point or press ENTER to apply hatch: <ENTER>

The reason for the particular rectangle coordinates of 16x10 is to maintain the 1.6:1 ratio that the other hatch slides in the ACAD.SLB are created with.

Before we prepare the slide however, it is recommended that we enter paper space and create a viewport to represent the slide. Slides are clipped at the viewport boundaries, and it would be difficult to maintain this without the viewport.

Command: TILEMODE
New value for TILEMODE <1>: 0
Command: MVIEW
ON/OFF/Hideplot/Fit/2/3/4/Restore/<First Point>: 0,0
Other corner: 16,10
Command: ZOOM
All/Center/Dynamic/Extents/Previous/Scale(X/XP)/Window/<Realtime>: E
Command: MSPACE

Finally we are ready to prepare the slide. However before doing so it is recommended that you create a unique directory/folder to contain this and other slides. We will need to add more slides to this directory to rebuild the ACAD.SLB. For terms of this discussion, will use C:SLIDES.

Issue the MSLIDE command, when prompted in the dialog enter C:SLIDESGRAVEL.SLD for the filename.

At this point we have our slide in the directory and ready to rebuild the ACAD.SLB.

6x48 Herringbone Hatch Pattern

Preparing to rebuild the ACAD.SLB: Just like we backed up the ACAD.PAT file, it is a very good idea to backup the ACAD.SLB file. You will also find this file in the AutoCAD support directory.

Since the SLIDELIB.EXE tool supplied with AutoCAD cannot simply append your slide to the SLB file, we will need to rebuild it from scratch containing the contents of the original SLB along with your slide.

Rebuilding the ACAD.SLB: Since SLIDELIB.EXE is an MS-DOS based tool, open an MS-DOS window and change to the slides directory.

C:WINDOWS>CDSLIDES

The easiest way to supply input to SLIDELIB.EXE is to prepare a file using the DOS DIR command. In this case we are also using the /ON switch to order by name, and the /B switch for bare (no size, date) listing. Finally with the > sign we are redirecting the output to create (or overwrite) the file SLIDE.INP.

C:SLIDES>DIR *.SLD /ON /B > SLIDE.INP

Now that we have an input file for the SLIDELIB utility, we can call it from the AutoCAD directory. For the most convenience, you may want to move or copy the SLIDELIB.EXE from the AutoCAD directory to the slides directory to eliminate the cryptic DOS path.

The Calling Command: C:SLIDES>C:PROGRA~1AUTOCA~1SUPPORTSLIDELIB ACAD.SLB < SLIDE.INP

6x48 Herringbone Hatch Patterns

If SLIDELIB.EXE was copied/moved:

C:SLIDES>SLIDELIB ACAD.SLB < SLIDE.INP

Overwriting the original ACAD.SLB

Use your preferred method to copy the new ACAD.SLB from the slides directory to the AutoCAD support directory, overwriting the old one.

The changes will be in effect immediately, simply issue the BHATCH command and see the rewards for your efforts.
