(if (null (tblsearch "LAYER" (getvar "USERS3"))) (entmake (list (cons 0 "LAYER") (cons 2 (getvar "USERS3")) (cons 70 0) (cons 62 7) (cons 6 "Continuous") ) ) ) Thanks. gteng5876 2012-09-08 12:26:20 http://www.zwsoft.com/forum/viewthread.php?tid=2423&pid=15948 Thank you, it worked well. gteng5876 2012-09-11 10:43:33 http://www.zwsoft.com/forum/viewthread.php?tid=2423&pid=15943 Corrected code: (if (null (tblsearch "LAYER" (getvar "USERS3"))) (entmake (list (cons 0 "LAYER") (cons 100 "AcDbSymbolTableRecord") (cons 100 "AcDbLayerTableRecord") (cons 2 (getvar "USERS3")) (cons 70 0) (cons 62 7) (cons 6 "Continuous") ) ) ) You can discover necessary DXF groups by reading existing layers. For example: (entget (tblobjname "LAYER" "0")) seav735587 2012-09-10 00:25:29
