Make a Linetype Active
To use a linetype to draw on the current layer, you must make it active. All newly created objects are drawn using the active linetype.
To make a linetype active, use the ActiveLinetype property. This property is set on the current drawing. For example:
ThisDrawing.ActiveLinetype = ThisDrawing. _
Linetypes.Item("CONTINUOUS")
For more information about activating a linetype, see “Set the Current Linetype” in the User's Guide.
