使⽤entmake创建图元必要条件
摘录⼀些entmake的⽅式创建图元的⽅法，以便后查。
1、直线
(entmake (list '(0 . "LINE") (cons 10 pt1) (cons 11 pt2)))
2、两顶点多段线（多顶点类似）
(entmake (list '(0 . "LWPOLYLINE") '(100 . "AcDbEntity") '(100 . "AcDbPolyline") (cons 90 2) (cons 10 pt1) (cons 10 pt2)))
3、点表⽣成多段线
(entmake (append (list '(0 . "LWPOLYLINE") '(100 . "AcDbEntity") '(100 . "AcDbPolyline") (cons 90 (length lst))) (mapcar '(lambda (pt)(cons 10 pt)) lst )) )
4、圆
(entmake (list '(0 . "CIRCLE") (cons 10 pt) (cons 40 r)))
5、圆弧
(entmake (list '(0 . "ARC") (cons 10 pt) (cons 40 r) (cons 50 ang1) (cons 51 ang2)))
6、单⾏⽂本
(entmake (list '(0 . "TEXT") (cons 1 str) (cons 10 pt) (cons 40 5)))
7、多⾏⽂本
(entmake (list '(0 . "MTEXT") '(100 . "AcDbEntity") '(100 . "AcDbMText") '(7 . "Standard") (cons 1 str) (cons 10 pt)))
8、半径标注
(entmake (list '(0 . "DIMENSION") '(100 . "AcDbEntity") '(100 . "AcDbDimension")(cons 10 pt) '(70 . 36) '(100 . "AcDbRadialDimension") (cons 15 pt1) ) )
9、直径标注
(entmake (list '(0 . "DIMENSION") '(100 . "AcDbEntity") '(100 . "AcDbDimension") (cons 10 pt1) (cons
11 pt2) '(70. 163) ' (100 . "AcDbDiametricDimension") (cons 15 pt3) ) )
10、⽔平标注
(entmake (list '(0 . "DIMENSION") '(100 . "AcDbEntity") '(100 . "AcDbDimension") (cons 10 pt) '(70 . 32) '(1 . "") '(100 . "AcDbAlignedDimension") (cons 13 pt1) (cons 14 pt2) '(100 . "AcDbRotatedDimension") ) )
11、垂直标注
(entmake (list '(0 . "DIMENSION") '(100 . "AcDbEntity") '(100 . "AcDbDimension") (cons 10 pt) '(70 . 32) '(1 . "") '(100 . "AcDbAlignedDimension") (cons 13 pt1) (cons 14 pt2) '(50 . 1.5708) '(100 . "AcDbRotatedDimension") ) )
12、倾斜标注
(entmake (list '(0 . "DIMENSION") '(100 . "AcDbEntity") '(100 . "AcDbDimension") (cons 10 pt1) '(70 . 33) '(1 . "") '(100 . "AcDbAlignedDimension") (cons 13 pt2) (cons 14 pt3) ) )
13、entmake⽣成普通块
(defun emkblk (ss pt name / i) (entmake (list '(0 . "block") (cons 2 name) '(70 . 0) (cons 10 pt))) (repeat (setq i (sslength ss)) (entmake (cdr (entget (ssname ss (setq i (1- i)))))) ) (entmake '((0 . "ENDBLK"))) (command "_.erase" ss "") (entmake (list '(0 . "INSERT") (cons 2 name) (cons 10 pt))))
14、entmake插⼊普通块
(entmake (list '(0 . "INSERT") (cons 2 name) (cons 10 pt)))
15 、entmake⽣成⽆名块
(defun emkunameblk (ss pt / i name) (entmake (list '(0 . "block") '(2 . "*U") '(70 . 1) (cons 10 pt))) (repeat (setq i (sslength ss)) (entmake (cdr (entget (ssname ss (setq i (1- i)))))) ) (setq name (entmake '((0 . "ENDBLK")))) (command "_.erase" ss "") (entmake (list '(0 . "INSERT") (cons 2 name) (cons 10 pt))) name)
16、将选择集做成属性块(选择集中单⾏⽂本作为属性)
(defun emkattblk (ss pt name / ent i) (entmake (list '(0 . "block") (cons 2 name) '(70 . 2) (cons 10 pt))) (repeat (setq i (sslength ss)) (setq ent (entget (ssname ss (setq i (1- i))))) (if (= (cdr (assoc 0 ent)) "TEXT") (entmake (list '(0 . "ATTDEF") (assoc 10 ent) (assoc 40 ent) (assoc 1 ent) (cons 3 (cdr (asso
c 1 ent))) (cons 2 (cdr (assoc 1 ent))) '(70 . 0))) (entmake (cdr ent)) ) ) (entmake '((0 . "ENDBLK"))))
17、⽣成图层
(entmake (list '(0 . "LAYER") '(100 . "AcDbSymbolTableRecord") '(100 . "AcDbLayerTableRecord") '(70 . 0) '(6 . "Continuous") (cons 2 name) ) )
18、创建新线型
(entmake (list '(0 . "LTYPE") '(100 . "AcDbSymbolTableRecord") '(100 . "AcDbLinetypeTableRecord") (cons 2 "BERDIG 5-545") ' (3 . "Border ____ ____ ____ ____ ____") '(70 . 0) '(73 . 2) '(40 . 15.0) '(49 . 10.0) '(74 . 0) ' (49 . -5.0) '(74 . 0) ) )
19、引线 (entmake (list '(0 . "LEADER") '(100 . "AcDbEntity") '(100 . "AcDbLeader") (cons 10 pt) (cons 10 pt1) (cons 10 pt2) ) )
20、构造线(entmake (list '(0 . "XLINE") '(100 . "AcDbEntity") '(100 . "AcDbXline") (cons 10 pt) (cons 11 pt1)))
21、椭圆 (entmake '((0 . "ELLIPSE") (100 . "AcDbEntity")(100 . "AcDbEllipse")(10 3969.6 4289.14 0.0)(11 -1828.47 0.0 0.0) (40 . 0.416093) (42 . 6.28319) ) )
22、 点
rotate属性
(entmake (list '(0 . "POINT") (cons 10 pt)))
23、entmake⽂字样式
(entmake (list '(0 . "STYLE") '(100 . "AcDbSymbolTableRecord") '(100 . "AcDbTextStyleTableRecord") (cons 2 name) '(70 . 0) (cons 40 h) (cons 41 w) '(3 . "romans.shx") '(4 . "Hztxts.shx") ) )
24、 建⽴第⼀级标注样式
(entmake (list '(0 . "DIMSTYLE")
'(100 . "AcDbSymbolTableRecord")
'(100 . "AcDbDimStyleTableRecord")
'(70 . 0)
(cons 340 (tblobjname "style" "Standard")) ; ⽂字样式名
(cons 2 "普通螺纹") ; 标注样式名
'(3 . "M<>") ; 标注前缀
'(40 . 0.0) ; 标注特征⽐例，缩放到布局
'(41 . 2.5) ; 箭头尺⼨
'(42 . 1.5) ; 起点偏移量
'(43 . 5.5) ; 基线间距
'(44 . 1.5) ; 超出尺⼨线
'(47 . 0.000) ; 上偏差
'(48 . 0.000) ; 下偏差
'(71 . 0) ; 公差⽆
'(77 . 1) ; ⽂字在尺⼨线上⽅
'(74 . 1) ;
'(140 . 3.0) ; ⽂字⾼度
'(141 . -2.5) ; 圆⼼标记
'(144 . 1.0) ; 测量⽐例单位
'(146 . 0.7) ; 公差⾼度⽐例
'(147 . 1.0) ; ⽂字从尺⼨线偏移
'(172 . 2) ; 尺⼨界线间连线
'(176 . 256) ; 随层
'(177 . 256) ; 随层
'(178 . 256) ; 随层
'(271 . 3) ; 尺⼨标注精度
'(272 . 3) ; 公差标注精度
'(275 . 0) ; ⾓度标注制式，⼗进制。
'(288 . 1) ; ⼿动放置尺⼨
)
)
25、点表⽣成样条曲线
(entmake (append
(list '(0 . "SPLINE") '(100 . "AcDbEntity") '(100 . "AcDbSpline") '(71 . 3)) (mapcar '(lambda (pt) (cons 11 pt)) ptlst) )
)
