Specifies the linetype of an object.
Supported platforms: Windows only
VBA:
object.Linetype
Type: All drawing objects, AttributeReference, Group, Layer, SubDMeshEdge, SubDMeshFace, SubDMeshVertex, SubEntity, SubEntSolidEdge, SubEntSolidFace, SubEntSolidNode, SubEntSolidVertex
The objects this property applies to.
Read-only: No (except for Group objects)
Type: String
The linetype of an object. The default linetype is the linetype of the layer (ByLayer).
The linetype values identify the series of dots and dashes used for drawing lines. If you do not specify a linetype, the current active linetype is used for a new entity. If a linetype is specified for an entity, the current active linetype is ignored. Use the ActiveLinetype property to set or query the current active linetype.
VBA:
Sub Example_Linetype()
    ' This example searches for the linetype DashDot. If it is
    ' not found, it is added from the acad.lin file. Then a
    ' line is created and changed to the DashDot linetype.
    
    ' Search the linetypes collection for the DashDot linetype.
    Dim entry As AcadLineType
    Dim found As Boolean
    found = False
    For Each entry In ThisDrawing.Linetypes
        If StrComp(entry.name, "DASHDOT", 1) = 0 Then
            found = True
            Exit For
        End If
