ISAHLUKO 11: UKUPHUMA KWENQUBO
Masibuyele emuva ebhokisini lengxoxo le- “Drawing Parameter”. Ithebhu "yokulandela umkhondo we-Polar ikuvumela ukuthi ulungiselele isici segama elifanayo. "Ukulandela umkhondo wePolar", njengokuthi "Ukulandela ukulandela isithombana sezinto", kukhiqiza imigqa enamachashazi, kepha kuphela uma ikhesa iwela, noma ukukhuphuka kukona, i-angle elicacisiwe, kungaba kusuka kusixhumanisi sokuqala (X = 0, Y = 0), noma kuvezwa iphoyinti lokugcina.
Ngokuvulwa kwe- "Object Snap" ne "Polar Tracking", i-Autocad ibonisa imigqa yokulandela imigqa engeli echazwe ebhokisini lengxoxo. Kulokhu, uma kunikezwe ukucushwa kwevidiyo yangaphambilini, kusuka kwephuzu lokugcina elisetshenzisiwe. Uma sifuna ukuthi ikhombise imigqa yokulandela ngomkhondo kuma-engela ahlukene, singawangeza ohlwini olusebhokisini lengxoxo.
Ngendlela efanayo ne- "Object Reference Tracking", "Ukulandela umkhondo wePolar" futhi kukuvumela ukuthi ukhombe ngaphezulu kwesethenjwa sezinto futhi kuzokhombisa ukuhlangana kwemigqa yokulandela imigodi ye-polar yesikhashana ethathwe kubo. Ngamanye amagama, nalesi sici, lapho kudonswa into entsha, singasho inkomba yezinto ("iphoyinti lokugcina", "quadrant", "isikhungo", njll.) Futhi kuzophuma izakhi ze-angular; lapho-ke sikhomba enye ireferensi lenye into, lapho sizobona khona ukuhlangana okungaphakathi kuvela ekulandeleleni kwamaphuzu womabili.
Ngakho-ke, sizogcizelela iqiniso lokuthi la mathuluzi a-3 ahlanganyelwe, "Inkomba ye-Object", "Ukulandela umkhondo ..." kanye "nokulandela umkhondo wePolar", asivumele ukuthi sikhiqize i-geometry yezinto ezintsha ngokushesha okusuka kulokho osekudwetshiwe futhi ngaphandle kokulimazeka. ngokunemba.
