Examples

VBA:

Sub Example_ExtensionLineWeight()
    ' This example creates a Dim3PointAngular object in model space
    ' and changes the extension lineweight to a thicker value
    ' using the ExtensionLineWeight property

    Dim AngleVertex(0 To 2) As Double
    Dim FirstPoint(0 To 2) As Double, SecondPoint(0 To 2) As Double
    Dim TextPoint(0 To 2) As Double
    Dim oldLWSetting As Boolean
    Dim CurrentSetting As String
    
    ' Turn on lineweight display to see the changes
    oldLWSetting = ThisDrawing.preferences.LineWeightDisplay

    ' Create the new Dim3PointAngular object in model space
    Set DimPointAngularObj = ThisDrawing.ModelSpace.AddDim3PointAngular(AngleVertex, FirstPoint, SecondPoint, TextPoint)
    ThisDrawing.Application.ZoomAll

    ' Read and display current extension lineweight
    CurrentSetting = DimPointAngularObj.ExtensionLineWeight
    Select Case CurrentSetting
        Case acLnWtByLayer: CurrentSetting = "ByLayer"

        Case acLnWtByLwDefault: CurrentSetting = "ByDefault"
        Case Else
    End Select
    
    MsgBox "The extension lineweight for this object is currently set to: " & CurrentSetting

    ' Change the extension lineweight
    DimPointAngularObj.ExtensionLineWeight = acLnWt100
    ThisDrawing.Regen acAllViewports
    
    ' Read and display current extension lineweight
    MsgBox "The extension line weight for this object is now set to: " & DimPointAngularObj.ExtensionLineWeight
    
    ' Return previous lineweight setting
    ThisDrawing.preferences.LineWeightDisplay = oldLWSetting
