AddHatch

Anonymous — Wed, 23 Feb 2000 17:35:10 GMT

My first attempt at Hatching. Took this right out of the example. The
acPLine displays correctly. I can manually hatch it. Errors out at the
line "Set HatchObj =" with "object doesn't support this property or
method". Can anyone spot my error?

Thanks, Don

Set acPLine = ac.ActiveDocument.ModelSpace.AddLightWeightPolyline(Data)
acPLine.Color = acBlue
acPLine.Closed = True

'Create the outer boundary for the hatch:
Dim OuterLoop(0 To 0) As AcadEntity
Set OuterLoop(0) = acPLine

'Define the hatch:
Dim HatchObj As AcadHatch
Dim PatternType As AcPatternType
Dim PatternName As String
Dim Associativity As Boolean

PatternType = acHatchPatternTypePreDefined
PatternName = "ANSI31"
Associativity = False
Set HatchObj = ac.ModelSpace.AddHatch(PatternType, PatternName,
Associativity)
'Append the Outer Loop:
HatchObj.AppendOuterLoop (OuterLoop)
HatchObj.Evaluate

Is ac a reference to the Application or the ActiveDocument? ModelSpace can
be fond in a document object, not the application object. Try this:
ac.ActiveDocument.ModelSpace.AddHatch

Frank,

Doh! That's it. The VBA procedures are in Excel, not AutoCad. So I've
defined:
Public ac As AcadApplication

So ac.ActiveDocument.ModelSpace.AddHatch is correct. Should'a typed it out
& the help boxes would have shown me this.

Trouble you with another?

PatternType = acHatchPatternTypePreDefined
PatternName = "EARTH"
Associativity = True
Set HatchObj = ac.ActiveDocument.ModelSpace.AddHatch(PatternType,
PatternName, Associativity)
'Append the Outer Loop:
HatchObj.AppendOuterLoop (OuterLoop)
HatchObj.PatternScale = 20
HatchObj.Evaluate

Errors at HatchObj.Evaluate with "pattern too dense". Doesn't seem to apply
the PatternScale Property. Any ideas?

Thanks again, Don

I must confess, I've never done a hatch in VBA but if I was doing this
manually, I would set the scale prior to evaluating the hatch (take a look
at the hatch dialog to see what I'm talking about). Perhaps you should set
your PatternScale immediately after creating the hatch object.

One other thing: depending on the size of your loops, a scale of 20 may
actually be too small. If my first tip doesn't work, try using a larger
scale.
