Examples

VBA:

Sub Example_TrueColor()
    ' This example draws a line and returns the RGB values
    Dim color As AcadAcCmColor
    Set color = AcadApplication.GetInterfaceObject("AutoCAD.AcCmColor.20")
    color.SetRGB 80, 100, 244
    
    Dim line As AcadLine
    Dim startPoint(0 To 2) As Double
    Dim endPoint(0 To 2) As Double
        
    startPoint(0) = 1#: startPoint(1) = 1#: startPoint(2) = 0#
    endPoint(0) = 5#: endPoint(1) = 5#: endPoint(2) = 0#
        
    Set line = ThisDrawing.ModelSpace.AddLine(startPoint, endPoint)
    ZoomAll
    
    line.TrueColor = color
    Dim retcolor As AcadAcCmColor
    Set retcolor = line.TrueColor
    
    MsgBox "Red = " & retcolor.Red & vbLf & _
