AutoLISP is returning nil when entmod-ing the following list.
(setq new_pline (list (cons 0 "LWPOLYLINE") (assoc 410 polyline_list) (cons 8 "defpoints") (cons 90 4) (cons 70 1) (cons 43 0) (cons 10 point03) (cons 10 point02) (cons 10 point01) (cons 10 point00) ) )
Can anyone tell me what else is required to complete the list. Thanks Cliff
