5.6'Ellipses
ʻO ka'ōlelo maʻamau,ʻo kahi ellipse kekahi mea i loaʻa nā wahi 2 i kapaʻiaʻo foci. ʻO ka huina o ka mamao mai kekahi wahi o ka ellipse i kekahi o ka foo, me ka mamao mai kēlā wahi ai kekahi mea'ē aʻe, e like mau ka nui o kekahi wahi'ē aʻe ma ka ellipse. ʻO kēia kona hōʻailona kūlana. Eia naʻe, no ka hanaʻana i kahi ellipse me ke Kaipopo,ʻaʻole pono e hoʻoholo i ka foci. Hiki i ke geometry o ka ellipse ke kau i kahi axis liʻiliʻi a me kahi axis nui. Ke kuʻina o ka nui iho (axis), a me nā nīnūnē (axis) mea ma ka liʻiliʻi loa no Autocad, i ka piko o ka ellipse, no laila, he papa hana e huki ellipses me ka miomio e hoike ana i ke-oaio? A, laila, i ka mamao a hiki i ka pauʻana o kekahi o na pua a laila ka mamao mai ke kikowaena a hiki i ka hopena o kahi axis. ʻO keʻano o kēiaʻano,ʻo ia ke huki i ke kumu hoʻomaka a me ka hopena o kahi axis a laila ka mamao i kekahi.
Ia manawa, elliptical arcs i ellipse Hoʻohana i hiki ke kūkulu i ka like me ka ellipse, ma ka hopena wale mākou hōʻike i ka loiloi mua a me ka hope waiwai o ka huina o ka olelo mai arcs. E hoomanao i ka paʻamau palapala koho Autocad, 0 waiwai no ka huina o ka ellipse coincides me ka nui iho (axis) a me ka piʻi pū i loko o counterclockwise, e like me ka hiki ke ike koke:
