1、1.计算所有线段总长度(加载后只需框选所有线段便可得出这些线段的总长度)(defunc:LL()(setvar"cmdecho"1)(setqen(ssget(list'(0."spline,arc,line,ellipse,LWPOLYLINE"))))(setqi0)(setqll0)(repeat(sslengthen) (setqss(ssnameeni)) (setqendata(entgetss)) (command"lengthen"ss"") (setqdd(getvar"perimeter"))(setqll(+ddll)) (s
2、etqi(1+i))) (princ"所选线条总长为:")(princll)(princ))2.标注所有线段(加载后只需框选所有线段便可得标注这些线段)(defunc:LLL()(COMMAND"UCS""")(setvar"cmdecho"1)(SETVAR"OSMODE"0)(setq AcadObject (vlax-get-acad-object) AcadDocument(vla-get-ActiveDocumentAcadobject) mSpace (vla-get-ModelSpaceAcaddocument));;选取需
