Nested entities & XData.

I wrote a routine that attaches xdata to a 3d solid when it's drawn. Then the solids are blocked for use and retrieval as one part. this all works great
The problem I'm having is recalling that xdata UNLESS the block is exploded.
I need to retrieve the data in reference to the block name. How can I select all items in the drawing that have been registered to "APP-A" without exploding the upper level block?

 

XDATA attached to an entity in a block definition must
be accessed by obtaining the block definition. You can
store individual xdata on block references but not on
entities within the block.

To get the xdata of a block definition entity you can
use either
1) tblobjname and entnext until you get the entity desired
or
2) nentsel and pick a particular entity.

Describe your application and you might get better answers.
Is each block inserted only once?
Would attributes work better for you?

block?

 

The application is as follows.

I have created a quick and easy way to draw different moldings around windows. Then the windows are blocked and inserted into different drawings. The moldings have Xdata attached to them - the length and type of molding.
I can explode every window and get a schedule of each cut length and type of molding to cut without a problem but then I can't count the number of times that window shows up on the floor plan. So in an effort to not EXPLODE and UNDO every time I need to make a cut list, I'd like to extract that xdata without exploding.

thanks

 

Then get the xdata by getting it from the block definition's
entities as I described in my last post.
