![]() The sequence of numbers following the *U prefix in the anonymous block name is automatically generated by AutoCAD and is not persistent between drawing sessions - that is, a new set of anonymous block names will be generated every time the drawing is opened. ![]() The *U# block name is not Unicode but simply an anonymous block name (though, I can understand how the confusion would arise), - I would hazard a guess that the 'U' prefix stands for 'Unnamed', just as anonymous dimension block references are prefixed '*D#' (there are also *A#, & *E# anonymous blocks if I recall).When syncing attributes in dynamic blocks, you should be able to sync the true (effective) dynamic block name, and attributes will be synced across all references of the dynamic block (including all anonymous references).The sync option in the BATTMAN command is the same as performing the ATTSYNC command, as SLW correctly states.I have no clue if this is even possible, but this task is painstakingly tedious because the *U# given to the blocks is in no way decipherable which means you must sync each block individually until you hit the block you need - when you have inserted 500 blocks the list is ridiculously long. What I'm looking for is a routine that would select all of the blocks within the BATTMAN menu only containing the *U# and apply the SYNC function. If I delete a block (*U500) the number is removed and the list continues from the highest number no matter if the block was deleted (*U501). The more blocks I insert into the drawing the longer the list. To avoid this I must select the *U# blocks from the list that represent all of the blocks I have inserted into the current drawing. Now here is the catch, when I place a dynamic block (Casework), enter the height and apply it to a layer, the attribute does not follow until I use the BATTMAN Sync feature, but if I simply select 'Casework' from the list the dynamic height is reset back to the blocks original state it was created. ![]() Once I save the drawing the attributes and fields update to reflect the new dynamic height, however, the attributes do not follow the objects to their new height, in order for this to happen I must use the BATTMAN Sync feature. They all insert at a standard dimension until I select it and edit the dynamic height. I have about 50 dynamic blocks I place into my drawings that update using fields. ![]()
