I am a newbie in VBA and am looking for code to draw lines by picking points on screen. Any comments?

when you say picking points are refering to selecting node (actual point objects) ?

Sorry, I have not said clearly. What I meant is pick any location on the screen display or input known coordinates.
Thanks

this is straight from the Autocad help files ~ a very good reference if you care to browse through it

Sub Example_GetPoint()
' This example returns a point entered by the user.

Dim returnPnt As Variant

' Return a point using a prompt
returnPnt = ThisDrawing.Utility.GetPoint(, "Enter a point: ")
MsgBox "The WCS of the point is: " & returnPnt(0) & ", " & returnPnt(1) & ", " & returnPnt(2) & vbCrLf & _
"(Enter the next value without prompting.)", , "GetPoint Example"


' Return a point, no prompt
returnPnt = ThisDrawing.Utility.GetPoint
MsgBox "The WCS of the point is: " & returnPnt(0) & ", " & returnPnt(1) & ", " & returnPnt(2), , "GetPoint Example"

' Return a point using a base point and a prompt
Dim basePnt(0 To 2) As Double
basePnt(0) = 2#: basePnt(1) = 2#: basePnt(2) = 0#
returnPnt = ThisDrawing.Utility.GetPoint(basePnt, "Enter a point: ")

MsgBox "The WCS of the point is: " & returnPnt(0) & ", " & returnPnt(1) & ", " & returnPnt(2)

' Create a line from the base point and the last point entered
Dim lineObj As AcadLine
Set lineObj = ThisDrawing.ModelSpace.AddLine(basePnt, returnPnt)
ZoomAll

End Sub
