5.6 Ellipses

Kwenikweni, cholumpha ndi chithunzi chomwe chili ndi malo a 2 otchedwa foci. Chiwerengero cha mtunda kuchokera kumalo aliwonse a ellipse kupita ku imodzi ya foci, kuphatikizapo mtunda kuchokera pa chinthu chomwecho mpaka kukulingalira kwina, nthawizonse chidzakhala chofanana ndi chiwerengero chomwecho cha chinthu china chirichonse mu ellipse. Ili ndilo tanthauzo lake lachidule. Komabe, kumanga ellipse ndi Autocad, sikofunika kudziwa foci. Maginito a ellipse angakhalenso ndi mzere waung'onong'ono ndi mzere waukulu. The mphambano ya olamulira aakulu ndi olamulira pang'ono ndi osachepera kwa AutoCAD, likulu la ellipse, kotero njira kudzatunga ellipses mwandondomeko akuonetsa likulu, ndiye mtunda ku mapeto a chimodzi cha migodi ya ndiyeno mtunda kuchokera pakati mpaka kumapeto kwa mzere wina. Njira yotsatilayi ndikutenga chiyambi ndi mapeto a mzere umodzi ndiyeno kutalika kwake.

Arcliptical arcs ndi zigawo za ellipse zomwe zingamangidwe mofanana ndi ellipse, koma potsirizira pake tiyenera kuwonetsa kuunika koyamba ndi kotsirizira kwa magulu awa. Kumbukirani kuti ndi malo osasinthika a Autocad, mtengo wa 0 pa mbali ya ellipse umagwirizana ndi majekiti akuluakulu ndikuwonjezereka, monga momwe mukuonera:
