Attribute Export (attext)

[Anonymous]

Using Autocad LT 2014 and a simple Template file;

BL:NAME C015000
TAG1  C040000
DESCR1 C030000

Some of me Block names export as '*U' .  Can't figure out why.  For example a block named PE_PLAN will export as '*U'

*U means it's undefined: are there empty or default entries in place?

Not sure what you mean.  Block attached.

That's because it's a dynamic block. AutoCAD will make an alias (anonymous) name for the block with *U name. Data extraction understand this is just alias and use the original name instead. But ATTEXT doesn't. You need to use only regular (not dynamic) block if you want to use ATTEXT.

In order for Autocad to know which block is which they have a name, but with dynamic blocks they can be altered so that they look different, in order for Autocad to keep track of these it gives them a second anonymous name, and the Autocad database uses these names internally, it also reports this name when you use the ATTEXT command (or when you use LIST), as a workaround I would add an attribute to the block and use that to keep the block name in.

Small addition: if the Dynamic Bloc is in its original position the BlockName will show.

If the position was changed (which is why we do dynamic blocks) it will show '*U'
