Create Lines

The line is the most basic object in AutoCAD. You can create a variety of lines—single lines, and multiple line segments with and without arcs. In general, you draw lines by specifying coordinate points. The default linetype is CONTINUOUS, an unbroken line, but various linetypes are available that use dots and dashes.

To create a line, use one of the following methods:

AddLine

Creates a line passing through two points.

AddLightweightPolyline

Creates a 2D lightweight polyline from a list of vertices.

AddMLine

Creates a multiline.

AddPolyline

Creates a 2D or 3D polyline.

Standard lines and multilines are created on the XY plane of the world coordinate system. Polylines and Lightweight Polylines are created in the object coordinate system (OCS). For information about converting OCS coordinates, see Convert Coordinates.

Sub Ch4_AddLightWeightPolyline()

    Dim plineObj As AcadLWPolyline

    Dim points(0 To 5) As Double

      
    ' Define the 2D polyline points
      
    points(0) = 2: points(1) = 4
      
    points(2) = 4: points(3) = 2
      
    points(4) = 6: points(5) = 4
      
      
    ' Create a light weight Polyline object in model space
      
    Set plineObj = ThisDrawing.ModelSpace. _
      
 AddLightWeightPolyline(points)
      
    ThisDrawing.Application.ZoomAll
