I have a large amout of P&ID drawings that have blocks with attributes. One of the blocks is missing an attribute field that I need so I recreated the block using the same name and added the missing attribute. When I reinsert the block and say "yes" to updating the block's definition within one of my P&ID drawings everything seems fine excepot when I try to edit the block to fill in that field. The newly added attribute doesn't show up but when I right click one of these blocks and select Block Editor the new attribute field does shows up so the redefine did work I just can't use that attribute. Is this a bug in AutoCAD? Any ideas as to how I can use this attribute?
