Thread: Draw function VBA

  1. #1

    Draw function VBA

    Hello,

    I'd like to draw a function with VBA for autocad, using a polyline. I'd like to use the following code:

    Sub Example_AddPolyline()

    Dim plineObj As AcadPolyline
    Dim points(0 To 10) As Double

    ' Define the 2D polyline points
    points(0) = 1: points(1) = f:
    points(2) = 2: points(3) = f:
    points(4) = 3: points(5) = f:
    points(6) = 2: points(7) = f:
    points(8) = 3: points(9) = f:

    Set plineObj = ThisDrawing.ModelSpace.AddPolyline(points)
    ZoomAll

    End Sub



    where points(even) are the x-axis units and points(odd) are the value of the function f (which is not important here) for the x-value.


    How could i do? Trying using a for-cycle maybe...?

    Thank you

    Hi ElCidCampead!
    You need to change "AddPolyline" into "AddLightWeightPolyline".
    "AddPolyline" need three direction coordinate, and change "Dim points(0 To 10) As Double" to "Dim points(0 To 9) As Double" if you want to create a 5 points polyline.

    additional remarks:
    "Dim plineObj As AcadPolyline" must be changed to "Dim plineObj As AcadLWPolyline".
