About Assigning the Hatch Pattern Type and Name (VBA/ActiveX)

AutoCAD supplies a solid-fill and more than fifty industry-standard hatch patterns.

Hatch patterns highlight a particular feature or area of a drawing. For example, patterns can help differentiate the components of a 3D object or represent the materials that make up an object.

You can use a pattern supplied with AutoCAD or one from an external pattern library.

To specify a unique pattern, you must enter both a pattern type and a pattern name when creating the Hatch object. The pattern type specifies where to look up the pattern name. When entering the pattern type, use one of the following constants:

acHatchPatternTypePredefined
Selects the pattern name from those defined in the acad.pat or acadiso.pat file.
acHatchPatternTypeUserDefined
Defines a pattern of lines using the current linetype.
acHatchPatternTypeCustomDefined
Selects the pattern name from a PAT other than the acad.pat or acadiso.pat file.

When entering the pattern name, use a name that is valid for the file specified by the pattern type.
