using autocad 14 and vba how would i get a list of xrefs in the current
drawing?

I''m new to VBA so excuse me for all the bad programming in this routine.
I'm trying to get it to tell me what xref's and nested xref's are in a
drawing and give their file path, insertion point and scale.
I can get this information for the main xref's but I can only seem to get
the name for the nested xrefs.
I cant seem to get my head round the difference between a block and a
blockreference and why I can can only get certain properties for each one.

Thanks

Graeme

The problem is this huge hole in the object model that exposes the path of
an XRef *only* via AcadExternalReference instead of thru the Block object.

Give this a shot:

Option Explicit

Public Sub Test()
Dim XRefs As New Collection
Set XRefs = GetXRefs

Dim XRef As AcadExternalReference
Dim ynInserted As Boolean
Dim i As Integer

For i = 1 To XRefs.Count
Set XRef = XRefs(i)
ynInserted = IsInserted(XRef)
Debug.Print _
"XRef name: " & XRef.Name & _
vbCrLf & "XRef path: " & XRef.Path
If ynInserted Then
Debug.Print _
"Inserted at: " & _
CStr(XRef.InsertionPoint(0)) & "," & _
CStr(XRef.InsertionPoint(1)) & "," & _
CStr(XRef.InsertionPoint(2)) & _
vbCrLf & "Scale factor: " & XRef.XScaleFactor
End If
Next i
End Sub

Private Function IsInserted(Block As AcadExternalReference) As Boolean
Dim BlockOwner As Long
BlockOwner = Block.OwnerID

If BlockOwner = ThisDrawing.ModelSpace.ObjectID Then
IsInserted = True
Exit Function
End If

Dim ThisLayout As AcadLayout
For Each ThisLayout In ThisDrawing.Layouts
If BlockOwner = ThisLayout.ObjectID Then
IsInserted = True
Exit Function
End If
Next ThisLayout
End Function

Private Function GetXRefs() As Collection
Dim ThisBlock As AcadBlock
Dim ThisObject As AcadEntity
Dim AnXRef As AcadExternalReference
Dim Result As New Collection
Dim i As Integer
For Each ThisBlock In ThisDrawing.Blocks
For Each ThisObject In ThisBlock
If TypeOf ThisObject Is AcadExternalReference Then
Set AnXRef = ThisObject
Result.Add AnXRef, CStr(i)
i = i + 1
End If
Next ThisObject
Next ThisBlock
Set GetXRefs = Result
Set Result = Nothing
End Function

Thank you Robert that worked almost perfect. To start with it listed the
name and path of them all, but only the scale and insertion point of the
first xref. By commenting out the If ynInserted ... line it worked
perfectly. Is the If ynInserted ... line important for something ?

OK forget what I said about binding drawings. I'm feeling kinda stupid now.
For some reason I thought that xrefs with nested xrefs could not be bound
but I just discovered that they can. But anyway, listing the xrefs is still
gonna be useful !

Yes.

However... binding XRefs that contain resolved XRefs pose no problem. Are
you trying to bind XRefs that contain *unresolved* or unloaded nested XRefs?

Yeah, we have to bind some drawings on a project and the drafter was having
a problem with it. It must have been that there are unresolved objects. It
could also be that the engineers stamp was unloaded instead of detached.

Thanks for your help
