Hi,this is my first post here, as I am reading here for several years now, and until now, every question was solved... :DBut now I have a problem the forum solved just not 100 % for me (but nearly, ok)....Our company is currently building up a library for hydraulic symbols, built of blocks with attributes, so the blocks can be mirrored, but the text ist not. As we are building up, the blocks do often change. To update all the blocks ATTSYNC is used, which works well, but does not set attribute back to default. I learned  BATTMAN has the same function as the ATTSYNC, but both do set back the value of the attribute only back to defaulft if the attribute is set to "constant" (which disables the mirror advantage...)ATTDEFAULT from here does solve this problem, but you have to select every single block...Is there a way to ATTDEFAULT all blocks?I have searched a lot, but found nothing, maybe somebody could helb me... (sadly I´m not able to code something myself...)RegardsBen
