I have the following lisp to use a certain leader head, defined by a drawing on our network. (prompt " Specify first leader point...") (setq GP (getpoint)) (prompt " Specify next point:") (command "SETVAR" "DIMLDRBLK" "ICON-ARROWHEAD" "QLEADER" GP PAUSE PAUSE PAUSE "" "SETVAR" "DIMLDRBLK" ".") but if the block is not already in the drawing, the lisp will not work and we have a lot of drawings already created without the block in the template drawing file. Is there a way to "quietly load the block for use in the lisp, without have to insert the block and deleting it? Thanks
