XRef Block is In cuur doc or Not

Hi All,

Is there a direct method to know whether a block whoes IsXRef property is directly inserted in the current document or is inserted in some other document which is inserted in this document.

I know that this can be done by seeing the inserted block references and comparing for the same name. But I don't want to do that. Is there any method or property of Block object by which we can find out it.

Thanks In advance

Manoj

 

Manoj,

Maybe this is an answer, or maybe it is not. It is an exerpt of code
from a routine where the user picks items to see info on that item
much like the properties tool but with the information you really want
to see.

Here the entity is picked with GetSubEntity. The very first thing that
must be determined is whether or not that picked item entity is from
another document just like what you are asking. In this case the
contextdata returned by GetSubEntity is what answers that question.
The variable MamaItem becomes the "other document". Later on in the
code (not shown here) the MamaItem.path is used to report that
document's name.


ThisDrawing.Utility.GetSubEntity PickedItem, pickedpoint,
transmatrix, contextdata
If Not (IsEmpty(contextdata)) Then
Set OtherItem = ThisDrawing.ObjectIdToObject(contextdata(0))
If UBound(contextdata) > 0 Then
Set MamaItem =
ThisDrawing.ObjectIdToObject(contextdata(UBound(contextdata)))
End If
Title = PickedItem.ObjectName & " part of " &
OtherItem.ObjectName
strStat = OtherItem.Layer & " = Insertion Layer"
strStat = strStat & vbCr & vbCr & PickedItem.Layer & " =
Layer in block definition"
Else
Title = PickedItem.ObjectName
strStat = PickedItem.Layer & " = Layer"
End If

Check the OwnerId property. If it's xref'd into the current document,
the OwnerId should match the ObjectId of the ModelSpace block (assuming
a model space insert).

 

Hi frank,

Thanks for your suggestion. I tried the same but the owner ID for all the blocks whether it is external reference, or simple block or a nested external reference, is same and the corresponding object is AcadBlocks object. So this won't be usefull for my problem.

Is there any other way.

Thanks again for your valuable effort.

You have to check the OwnerId property on the insert, not the block.

 

Just look at the Database property of the Block object.

reference, or simple block or a nested external reference, is same and the corresponding object is AcadBlocks
object. So this won't be usefull for my problem.

 

Hi Tony & ask,

Thanks for your suggestion but as per your suggestion I need to pick the object on the screen interactivly, but I don't need to do that. I am iterating the block collection, if the block is external reference and is directly inserted in the current drawing then I need to reload the block so that any changes made in the block will be get reflected. So here there is no scop for picking the object on the screen.

One method is that if the block reference is an external reference take its name, iterate block-reference collection and find is there a reference with the same name?, If yes, then it is an external reference inserted in the current drawing, otherwise the external reference is not in current drawing. But the problem is that some of my drawings have more than 2000 block reference. If there are 10 external reference blocks in the drawing then I will have to iterate upto 20000 times which I don't want. So Is there any other method.

Hi tony you have suggested to look at Database property, but the database property will provide me the database of the external reference. What property will suggest that the block is directly inserted in the current drawing or is inserted in some other drawing which is inserted in this drawing?
