In many fields (eg. Civil Engeneering (USCS, DIN 4023, ...), Architecture, Geosciences, Cartography, ...) complex hatch patterns are needed for a clear graphical representation.
AHatch Pro is a flexible tool for the design of AutoCAD hatch patterns. The generated hatch patterns can be used with the AutoCAD "hatch" and "bhatch" commands. AHatch Pro is developed as a stand-alone program and may be used independently of Autodesk AutoCAD.
