Copy block attributes from one block to another

[thorny]

test.lspTitle Blocks.dwg

Hi. I am hoping that someone may be able to help me achieve copying and pasting attributes from one title block to another.

I have found a lisp which works to a certain degree, but has 2 issues:

1. You cannot copy and paste from a block in layout 1 to layout 2.
2. Our blocks have some duplicated attribute names eg 3xTitle & 2xSite

I have attached a dwg containing 2 of our borders and the lisp to help explain.

I understand that the duplicated attributes within each border may posses a challenge to overcome, but we have quite a lot of borders for various tasks and would be great if we didn't have to change the attribute names to eg. Title 1, Title 2, Title 3 etc...

Obviously if this cannot be overcome, but you can copy attributes across various layouts, that would be hugely advantagous in itself.

Cheers

This may help you with it , So check it out Buddy .

Hi Tharwat

Thanks for the code. However I cannot seem to run it. I have loaded it in using APPLOAD, but when I close the Appload Window I get "; error: malformed list on input" at the command line.
I have tried running typing "Action," but it doesn't work. Am I missing something simple here?

Hi Thorny,

Nice to see a few other Brits around here

To my knowledge, you can't use LISP to manually select blocks in different layouts since upon switching layouts, the LISP is cancelled.

However, this offers another approach which will allow you to select a block and update all blocks with the same name (it should also hopefully work with your blocks with multiple tags with the same name).

Call with 'test':

Heres the same thing almost in VBA the original idea behind it was a single title block change no matter how many title blocks the extra code allows for pick a block that identifies the block name hope all this makes sense. Just run the add_project_number it will work with your block, change DA1DRTXT to your block name.

Public Sub add_project_number()
' This Updates the project number
Dim SS As AcadSelectionSet
Dim Count As Integer
Dim FilterDXFCode(1) As Integer
Dim FilterDXFVal(1) As Variant
Dim attribs, newtext As Variant
Dim BLOCK_NAME As String
'On Error Resume Next
Dim startCH As Double
newtext = ThisDrawing.Utility.GetString(True, "Enter new project code : ")
FilterDXFCode(0) = 0
FilterDXFVal(0) = "INSERT"
FilterDXFCode(1) = 2
FilterDXFVal(1) = "DA1DRTXT"
BLOCK_NAME = "DA1DRTXT"
Set SS = ThisDrawing.SelectionSets.Add("issued")
SS.Select acSelectionSetAll, , , FilterDXFCode, FilterDXFVal

For Cntr = 0 To SS.Count - 1
   attribs = SS.Item(Cntr).GetAttributes
        
        
        attribs(1).TextString = newtext
                attribs(1).Update
         
Next Cntr
ThisDrawing.SelectionSets.Item("issued").Delete

End Sub

and

Function Getpitname(Newpitname As String) As String
Dim PitNameSelect As AcadObject
Dim pitattribs As Variant

ThisDrawing.Utility.GetEntity PitNameSelect, basepnt, "pick pit name : "
If PitNameSelect.ObjectName = "AcDbText" Then
  Getpitname = PitNameSelect.TextString
End If
If PitNameSelect.ObjectName = "AcDbBlockReference" Then
  pitblname = PitNameSelect.Name   ' RETURNS BLOCK NAME
  pitattribs = PitNameSelect.GetAttributes
  Getpitname = pitattribs(0).TextString
End If

End Function

you need to change the line newtext = ThisDrawing.Utility.GetString(True, "Enter new project code : ") to

Dim PitNameSelect As AcadObject
ThisDrawing.Utility.GetEntity PitNameSelect, basepnt, "pick pit name : "
Newpitname = "1"  'dummy to pass then return changed
pitname = Getpitname(Newpitname)
'Call Getpitname(pitname)
MsgBox "pitname selected is " & pitname

Hi Tharwat

That's for sure that you have missed one of the parenthesis while copying codes to your Cad , and that might be the last bracket I guess .

Retry it and good luck

Thanks for all the replies. Unfortunately nothing is quite working specifically for what we need although the lisps you have provided are great in their own rights. The bit that is not quite working is copying and pasting attibutes from one block to another (with different names), whilst swithing layouts. Swithing the layouts always terminates the lisps. The closest routine I found was http://www.cadtutor.net/forum/showth...all-attributes. Thanks alanjt for this. Is there anyway of switching between layouts whilst in a lisp? Or is there a way to update the attibutes globally (even if the blocks have different names), something similar to the ATTEDIT command, but not having to select the block?

Thorny,

Mine will currently update blocks of the same name, but you can add other block names to the filter:

Shown in red is the name of the selected block, and shown in green are additional blocks to be updated.

On mine, you could just type "ALL" when it comes to the multiple selection of blocks to update. This is a little shaky when you are NOT filtering based on matching block name, and will update if has matching attribute tag.
