I'm trying to change a group of attributes in a block, there are 52 attribute all having a similar value to modify. The original ACAD_LT command was EDITATT it would then ask if the block name then if the edit one at a time or as a group the I could change all. If I enter this command in draftsight returns with EDITBLOCKATTRIBUTE and asks to Specify block» I have tried to enter the name of the block I get invalid entry If I Pick from the screen I get a Dialog box requiring individual replacments

Any suggestions?
