Izifunda ze-6.6
Kusenolunye uhlobo lwento eyinhlanganisela esingayidala nge-Autocad. Imayelana nezifunda. Izifunda yizindawo ezivaliwe lapho, ngenxa yesimo sazo, kubalwa izinto ezibonakalayo, njengezindawo zamandla adonsela phansi, ngakho-ke kwezinye izimo kuzoba lula ukusebenzisa lezi zinhlobo zezinto esikhundleni sama-polylines noma ezinye izinto.
Singadala into yesifunda kusuka, ngokwesibonelo, i-polyline evaliwe. Kodwa-ke, zingadalwa futhi ngokuhlanganiswa kwama-polylines, imigqa, ama-polygons ngisho nama-splines, inqobo nje lapho akha izindawo ezivalekile ngendlela efanayo. Lokhu kusebenza okuhlukahlukene kuyasivumela ukudala izinto zesifunda sisebenzisa imisebenzi yeBoolean, okungukuthi ukwengeza noma ukukhipha izindawo, noma kusuka ekuxhumaneni kwazo. Kepha ake sibheke le nqubo ngezingxenye.
Isifunda ngaso sonke isikhathi sidalwa kusukela ezintweni ezivele zidonswe ezakha izindawo ezivalekile. Ake sibheke izibonelo ezimbili, esisodwa esivela ku-polyline kanti esisodwa sivela ezintweni ezilula ezidambisa indawo ngokusobala.
Umbuzo wezakhiwo ezibonakalayo zesifunda uzofundwa ku-Isahluko 26, okwamanje, singasho ukuthi singakha futhi izifunda kusuka ezindaweni ezivalekile sisebenzisa umyalo othi "CONTOUR", yize lo myalo ungadala nemapholine. Ake sibheke umehluko walunye noma kolunye.
Futhi singangeza izifunda ezimbili endaweni entsha ngomyalo we- “UNION”. Futhi, izifunda zingaqala kusuka kuma-polylines noma amanye amafomu avaliwe kuqala.
Ukusebenza kwe-Boolean esebenzayo kubuye kusebenza, okungukuthi, esifundeni esisodwa kuthathe esinye futhi kutholwe isifunda esisha njengomphumela. Lokhu kutholakala ngomyalo we- "DIFFERENCE".
Umsebenzi wesithathu wamaBoolean ukuhlangana kwezifunda ukuthola isifunda esisha. Umyalo ngu- "INTERSEC."
