I am sure this has probably been done but I am new to CAD. I am working with MEP2014. I need a lisp routine to be able to search multiple types of blocks based off an attribute value (i.e. a device address) that each block has associated to it. All the blocks are at 0,0 origin and I need to select a block from that attribute and move it to 1,0 then next one to 2,0 etc etc etc so they create a line in the order I need them in. Any help would be appreciative. Thanks
