Nested Copy

Anonymous — Fri, 02 Apr 2004 07:37:05 GMT

I wanted to write my own nested copy command in VBA that is like the NCOPY Express Tool except does not prompt for base and displacement points. (I also find NCOPY to be slow) I thought it would be quite simple but it doesn't seem to be simple enough for me. I can get a subentity a tell if it is nested one level down from a Block or XREF but can't work out how to copy it into modelspace. Any help will be greatly appreciated. This code is as far as I got:
----------
Option Explicit

Public Sub test()
Dim objEnt As AcadEntity
Dim varPickedPoint As Variant
Dim varTransMatrix As Variant
Dim varContextData As Variant
Dim objEntParent As AcadEntity
On Error GoTo ErrorHandler
ThisDrawing.Utility.GetSubEntity objEnt, varPickedPoint, varTransMatrix, varContextData
On Error GoTo 0
If IsEmpty(varContextData) = False Then
If UBound(varContextData) = 0 Then
Set objEntParent = ThisDrawing.ObjectIdToObject(varContextData(0))
If TypeOf objEntParent Is AcadBlockReference Then

End If
End If
End If
Exit Sub
ErrorHandler:
Resume
End Sub

Refreshed after the weekend I worked out how to copy an object in a XREF in to modelspace. So if anyone was interested here is the code.
----------
Option Explicit

Public Sub test()
Dim objEnt As AcadEntity
Dim varPickedPoint As Variant
Dim varTransMatrix As Variant
Dim varContextData As Variant
Dim objEntParent As AcadEntity
Dim objEnts(0) As AcadEntity
Dim varReturned As Variant
On Error GoTo ErrorHandler
ThisDrawing.Utility.GetSubEntity objEnt, varPickedPoint, varTransMatrix, varContextData
On Error GoTo 0
If IsEmpty(varContextData) = False Then
If UBound(varContextData) = 0 Then
Set objEntParent = ThisDrawing.ObjectIdToObject(varContextData(0))
If TypeOf objEntParent Is AcadExternalReference Then
Set objEnts(0) = objEnt
varReturned = ThisDrawing.Blocks(objEntParent.Name).XRefDatabase.CopyObjects(objEnts, ThisDrawing.ModelSpace)
End If
End If
End If
Exit Sub
ErrorHandler:
Resume
End Sub

I spoke too soon. The CopyObjects method returns "Invalid owner object" when text is selected.

Just in case anyone is interested here is what I ended up with. I find it quicker and easier than NCOPY but it does not copy multiply nested objects or objects containing nested objects.
