entmake创建图元
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)
)
)
