ISAHLUKO 12: UKUPHATHISWA KWAMAPHAKATHI
Lapho sisebenzisa ireferensi iphuzu lokugcina, noma iphuzu lesikhungo, ngokwesibonelo, esikwenzayo ngempela ukuphoqa into entsha ukuthi yabelane ngephuzu lejometri yayo nenye into esivele idonswe. Uma sisebenzisa ireferensi "Parallel" noma "Perpendicular", okufanayo kuyenzeka, siphoqa ukuhlelwa kwejometri yento entsha maqondana nenye, ukuze kuthi uma kungafani nokufana, ngokubheka kwecala nangokunye kokukhethwa kukho, leyo nto entsha ngeke ikwazi kudalwe.
I- "Parametric Conraints" ingabonakala njengokunwetshwa komqondo ofanayo ofaka izinkomba zezinto. Umehluko ukuthi ukuhlelwa kwejometri okusunguliwe kuhlala kuyisidingo sokuthi into entsha kumele igcwalise unomphela, noma kunalokho, njengomkhawulo.
Ngale ndlela, uma sakha umugqa njengento ehambisana nomunye, ngakho-ke kungakhathaliseki ukuthi sishintsha kanjani enye enye umugqa, into enomkhawulo kufanele ihlale iyingqayizivele.
Ngokusobala, ukusetshenziswa komkhawulo kunengqondo uma sishintsha into. Lokhu kungukuthi, ngaphandle kwemingcele singenza noma yiziphi izinguquko kumdwebo, kodwa njengoba lezi zikhona, izinguquko ezingenzeka zingalinganiselwe. Uma sifuna amanzi AutoCAD entweni ekhona vele ukuthi aludingi ushintsho ke akunandaba mqondo ukusebenzisa ngendlela parametric umdwebo izivimbelo ezinjalo. Uma, ngokuphambene nalokho, senza umdwebo wesakhiwo noma ingxenye engumshini ogama lakhe lokugcina esalifunayo, imingcele ye-parametric iyasiza kakhulu, ngoba isivumela ukuba silungise lezo zinsuku phakathi kwezinto, noma ubukhulu bazo, ukuthi Umklamo kufanele uhambisane.
Faka enye indlela: iziphazamiso ze-parametric iyithuluzi elikhulu lemisebenzi yokuklama, ngoba lisenza ukuthi silungise lezo zinkinga ezinobuningi babo noma ubudlelwane be-geometric kumele zihlale zihlala njalo.
Kunezinhlobo ezimbili zemingcele ye-parametric: iJometri ne-Cota. Elicacisiwe izingqinamba lokuqala weJiyomethri lezinto (perpendicular, okufanayo, mpo, njll), kuyilapho izingqinamba ntathu setha ngohlangothi (amabanga, engeli futhi radii nge value othize). Isibonelo, umugqa kufanele ube njalo amayunithi we-100 noma imigqa emibili kufanele njalo idale i-angle ye-47 ° degrees. Ngakwelinye ihlangothi, izingqinamba eboshiwe ungaboniswa njengoba zibalo, ukuze ubukhulu sokugcina into kusekelwe amagugu (variable noma njalo) of the equation yakhiwa.
Njengoba sizofunda Amathuluzi wokuhlela izinto ezibuthelelweko kusuka esahlukweni 16, bheka lapha indlela ukudala, buka bese uphatha izingqinamba parametric, kodwa sizobuya kubo kuleso sahluko.
