HGEN - Hatch Pattern Generator

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.


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
