Problem Getting AcadBlockReference Object

Has anyone else had problems getting an AcadBlockReference object by setting it this way: Set AcadBlockRef = ModelSpaceObj.Item("AcadBlockRefName") where "AcadBlockRefName" is the name of the block reference object. Sometimes this method works and sometimes it doesn't. The only way I can get the BlockRef object 100% of the time is by iterating through all the items in Modelspace like this
For Each EntityObj in ModelSpaceObj
If TypeOf EntityObj is AcadBlockReference Then
Set AcadBlockRef = EntityObj
If AcadBlockRef.Name = "AcadBlockRefName" Then
Exit For
Endif
Next


Thanks,

Darren

 

Where did you get the idea that the Item method
accepts the name of a block reference?

It doesn't. Common sense would suggest that
since there can be more than one insertion of a
block of a given name, that you could not use the
name as an index key.

1) In my particular case, all block reference objects have unique names. 2) I got the idea of setting object references using the Item method from this discussion group. I tried it and it worked in my test case.

 

You can use the name form of the item method on the block
collection but I am sure the name form does not work in the
modelspace collection. Why not use filtered selection sets?
