Post a “before and after” drawing. That is usually the best illustration of a problem requiring automation.

Attach the sample drawing with your valves, arrows and

pipeline here

Use 'Manage attachments' button below message window

Save dwg as A2007 (I'm using A2008)

You did not show in the drawing where are your arrows, and

and what you want

And also there are no valves you talking about in there:x

It's a really big mess for me

In this case I can't help, sorry

Try to draw again what you have so far and what you want

to get after the program would be executed

As SEAN said attach "before and after" drawing instead

Hope it's clearly enough

Bhargav1987,

 

In the latest posted Drawing1.dwg, are the arrows on spans 278-279 and 279-280 actually pointing in the correct direction?

This may be a viable alternative to searching for the closest line. Run the routine with the attached file and window select the text entities.

 

Private Sub InsertArrow()
Dim fType(1) As Integer
Dim fData(1) As Variant
Dim entText As AcadText
Dim ent As AcadEntity
Dim dblValue As Double
Dim dblRotation As Double
Dim entInsert As AcadBlockReference

  fType(0) = 0: fData(0) = "TEXT"
  fType(1) = 62: fData(1) = 202
  If SoSSS(fType, fData) > 0 Then
     For Each entText In ThisDrawing.SelectionSets.Item("TempSSet")
        dblValue = ThisDrawing.Utility.DistanceToReal(entText.TextString, acDecimal)
        dblRotation = entText.Rotation
        If dblValue > 0 Then
            Set entInsert = ThisDrawing.ModelSpace.InsertBlock(entText.InsertionPoint, "ArrowPos", 1, 1, 1, dblRotation)
        Else
           Set entInsert = ThisDrawing.ModelSpace.InsertBlock(entText.InsertionPoint, "ArrowNeg", 1, 1, 1, dblRotation)
        End If
     Next
  End If
End Sub

Sub SSClear()
Dim SSS As AcadSelectionSets
  On Error Resume Next
  Set SSS = ThisDrawing.SelectionSets
     If SSS.Count > 0 Then
        SSS.Item("TempSSet").Delete
        SSS.Item("RemoveSSet").Delete
        SSS.Item("EntireSS").Delete
     End If
End Sub

Function SoSSS(Optional grpCode As Variant, Optional dataVal As Variant) As Integer
  Dim TempObjSS As AcadSelectionSet
  SSClear
  Set TempObjSS = ThisDrawing.SelectionSets.Add("TempSSet")
        'pick selection set
  If IsMissing(grpCode) Then
     TempObjSS.SelectOnScreen
  Else
     TempObjSS.SelectOnScreen grpCode, dataVal
  End If
  SoSSS = TempObjSS.Count
End Function
