Topic: Search for nested anonymous blocks

My suggestion:

Roy, be aware that your functions KGA_Conv_Pickset_To_EnameList & nestedEnmList are adding unnecessary loops to the processing and therefore introducing inefficiency.

Every block is analysed only once, so I don't think there are unnecessary loops. But the lists that are returned by these functions do entail some overhead. Maybe that is what you mean?

Thanks for the info

When you step through the block table, you can get the 'block' entity by
(tblobjname "block" <block name>)
Then code 330 is the 'block record'
Then you can look right after code '(102 . "{BLKREFS")' at code 331, these are inserts of the block.
Once you get those inserts, then you can check code '330' the 'block record'
To see if there is a '340' which would be the layout.

(tblobjname) didn't come around until ACAD 2000
group 330 by ACAD 2004

It is good to know though

KGA_Conv_Pickset_To_EnameList iterates over the selection set only to construct a list which is then iterated using another loop; similarly, nestedEnmList iterates over the block components only to construct a list which is then iterated to check for INSERT entities - this check and any further processing could be performed whilst iterating over the block components to avoid the extra processing loop.

... avoid the extra processing loop.

OK, so I have understood you correctly. Mind you this overhead is minute compared to the overhead I have referred to earlier. And of course BricsCAD has a built-in function vle-selectionset->list. Using that instead of my KGA_Conv_Pickset_To_EnameList would make this overhead even smaller.
