I-6.1 Polylines

I-Polylines yinto eyenziwe ngamagceke emigqa, ama-arcs, noma ukuhlanganiswa kokubili. Futhi ngenkathi singathola imigqa lwesikhathi ezimele kokuba njengoba yekucala endaweni yokugcina lomunye umugqa noma arc, futhi ngaleyo ndlela ukudala amafomu esifanayo, polylines unayo inzuzo ukuthi zonke izingxenye ukuthi yakha behave njengendlela into eyodwa . Ngakho, sivamile ezimweni lapho Kungcono ukwakha izingxenye polyline lemigqa futhi lwesikhathi ezimele, ikakhulukazi lapho kufanele senze ukulungisa, kuba lula ukuhlela izinguquko kwi intfo yinye eziningana. Enye inzuzo ukuthi sikwazi ukuchaza kokuqala kanye nobubanzi siphetfo polyline ingxenye eyodwa bese uphinde ushintshe ukushuba ngoba ingxenye yesibili. Ngaphezu kwalokho, ukwakhiwa kwe-polylines kuqinisekisa ukuthi iphuzu lokuqala lesigaba se-line noma i-arc lixhunyaniswe nengxenye yangaphambilini. Lokhu Inyunyana uyomenzela omunye vertices of polyline futhi ngisho nalapho senza ushintsho ukuzelula kancane noma ngokuhambisa (njengoba zichaziwe ngezansi), ukuxhumana phakathi izingxenye ezimbili kuhlala kusemthethweni, okuvumela ngokuphepha ukudala wabuka avaliwe, okuyinto kunezinzuzo ahlukahlukene bayokwazisa kamuva: lapho sibona izifunda kulesi sahluko esifanayo nalapho sifunda uhlelo lwezinto nokuthungatha.

Njengoba i-polylines ziyizingxenye zemigqa kanye nama-arcs, okukhethwa kukho okuhambisanayo kusenza sikwazi ukuchaza imingcele esivele siyayazi ukudala imigqa noma ama-arcs kumuntu ngamunye. Uma senza umyalo wokudala i-polylines, i-Autocad isicela ukuthi siqale iphuzu lokuqala, ukusuka lapho singanquma ukuthi ingxenye yokuqala ingumugqa noma i-arc, ngakho-ke, ikhombisa imingcele edingekayo ukuze uyidwebe.

Uma sesidonse izingxenye ezimbili noma ngaphezulu, phakathi kokukhethwa komugqa womyalo ukuvala i-polyline, okungukuthi, ukujoyina iphuzu lokugcina lokuqala neyokuqala. I-polyline ivaliwe nge-arc noma umugqa kuye ngokuthi isimo sigaba sokugcina sithathwe kanjani, nakuba kusobala ukuthi akuyona igunya ukuvala i-polyline. Okokugcina, cabanga ukuthi kungenzeka ukuthi ushintshe ubukhulu bokuqala nokugcina kwesigaba ngasinye se-polyline, okwandisa amathuba ayo ekudalweni kwamafomu.
