Edit Hatch Boundaries
Edit Hatches
Use Layers, Colors, and Linetypes
You can change the angle or spacing of an existing hatch pattern or replace it with a solid-fill or one of the predefined patterns that AutoCAD offers. The Pattern option in the Boundary Hatch dialog box displays a list of these patterns. To reduce file size, the hatch is defined in the drawing as a single graphic object.
Use the following properties and methods to edit the hatch patterns:
Change the pattern spacing of a hatch
This example creates a hatch. It then adds two to the current pattern spacing for the hatch.
Sub Ch4_ChangeHatchPatternSpace()
Dim hatchObj As AcadHatch
Dim patternName As String
Dim PatternType As Long
Dim bAssociativity As Boolean
' Define the hatch
patternName = "ANSI31"
PatternType = 0
bAssociativity = True
' Create the associative Hatch object
Set hatchObj = ThisDrawing.ModelSpace. _
AddHatch(PatternType, patternName, bAssociativity)
' Create the outer loop for the hatch.
Dim outerLoop(0 To 0) As AcadEntity
Dim center(0 To 2) As Double
Dim radius As Double
center(0) = 5
center(1) = 3
center(2) = 0
radius = 3
Set outerLoop(0) = ThisDrawing.ModelSpace. _
AddCircle(center, radius)
hatchObj.AppendOuterLoop (outerLoop)
hatchObj.Evaluate
' Change the spacing of the hatch pattern by
' adding 2 to the current spacing
hatchObj.patternSpace = hatchObj.patternSpace + 2
hatchObj.Evaluate
ThisDrawing.Regen True
