Kaha 3D me AutoCAD - Paukū 8
37.1.5 Propellers
ʻO ka'ōlelo maʻamau, ma Autocad he helix kahi spline o ke kāleka'ōnaehana i ka māhele 3D. He hāmamaʻo ia me kahi radi kumu, kahi aho kiʻekiʻe a me kekahi kiʻekiʻe. No ke kūkuluʻana i he helix, hoʻohana mākou i ke pihi me ka inoa like i loko o ka Mahele huki o ka Home tab. E noi ana ka papa kuhikuhi kauoha i ka helu waena o ka base, a laila ka radius o ke kumu, a laila ka laulā kiʻekiʻe a, ma hope, ke kiʻekiʻe. Loaʻa iā mākou ka koho e wehewehe i ka heluna o nā huli a me ke kuhikuhi o ka mimi, ma waena o kekahi. Inā like like ka base a me ka'ōkule kiʻekiʻe, a laila, e loaʻa iā mākou he helix cylindrical. Inā heʻokoʻa ke kumu o ka base a me ke ahupuaʻa kiʻekiʻe, e loaʻa iā mākou he helix conical. Ināʻokoʻa ka radi kumu a me ke ahupuaʻa luna a like ke kiʻekiʻe me ka zero, a laila, e loaʻa iā mākou kahi kikowaena ma ka māhele 2D, e like me nā mea a mākou i aʻo ai ma ka māhele 6.5.
E like me he spline, pono nā mea propellers e kumu e aʻo i ka māhele 36.1. ʻOiai ke nānā ponoʻoe,ʻo ka pihi e huki ai iā lākou e pili ana i nā mea kiʻi kiʻi kikokikona 2D, e like me nā pale kuhikuhi a me nā pōʻai. ʻO ka hopena o kēia kauoha ke hui pūʻia me kēia kauoha Sweep, ka mea a mākou iʻike ai ma ka māhele 37.1.2, i hiki iāʻoe ke hana i nā mea pale i keʻano o ka puna ma kahi alalahi a me ka wikiwiki. No kēia mākou e hoʻohana ana i kahi poʻomaka e lilo i mea hōʻike,ʻo ka pulupili,ʻoiaʻiʻo, e lilo ia i kumuhana.
Nā XitUM Primes
Ke kapa nei mākou he mau mea paʻa loa:'āpana pīkoka'āpana, sphere, cylinder, cone, wedge and toroid. Hiki iāʻoe keʻike i kēlā papa inoa iho-lalo ma loko o ka Māhele Hoʻohālike o kaʻaoʻao Home, a ma ka mahele mua o ka Palena Solid. E like me ka mea heluhelu e hiki ai, i ka manawa o ka hoʻolālāʻana, e noi ana ka pūnaewele hoʻonohonoho i nāʻikepili kūpono e like me ka paʻakikī i nīnauʻia. ʻO kaʻoiaʻiʻo, he nui kēia mauʻike a me ke kaʻina e noi aiʻo Autocad iā lākou, e like me nā mea 2D mea i laweʻia mai. No ka laʻana, no ka hanaʻana i kahi kikowaena AutoCAD, e noi anaʻoe i kahi kikowaena a me kahi radius e kuhikuhiʻia, me he mea lā he pōʻai. I ke kumu o kahi'āpana pālua, nā koho mua e pili pono i nā mea a mākou e hoʻohana ai e kahaki i kahi'āpana'āpana, a me ka kiʻekiʻe, o ka papa. No nā pyramids mākou e huki mua i kahi polygon, etcetera. No lailaʻaʻole kūpono e noʻonoʻo e pili ana i keʻano o kaʻikeʻana i nā mea unuhi kiʻi 2D i mea e pono ai no ke kahaʻana i nā mea 3D.
E nānā i nā mea e pono ai e kahakiʻi i nāʻano o nā kumu mua a mākou i helu ai. ʻAʻohe meaʻeha e hōʻike iāʻoe e hana i nā mea maʻamau i kāuʻike ma kāu kamepiula ma ka hoʻokolohuaʻana i nā koho o kēlā me kēia.
Ma kekahiʻaoʻao, inā mākou e hoʻohana i kahi kiʻikuhi kiʻi e hōʻike ana i nā hale i hoʻopaʻaʻia, e like me kā mākou iʻike ai ma ka'āpana 35.6, a laila, ma keʻano paʻamau, ua hoʻohālikeʻia keʻano o nā mea paʻa i nā laina 4. ʻO ka laulā e hoʻoholo ana i ka helu o nā laina e kū ana i ka paʻakikūʻo Isolines. Inā mākou e kākau i ka hoʻololi i ka puka kauoha a hoʻololi i kona waiwai, a laila hiki ke hoʻonohonohoʻia nā solids me nā laina hou, akā,ʻoiaʻiʻo,ʻo kēia ka hopena o ka wikiwiki o ka hoʻomou houʻana o nā kiʻi. ʻOe maoli ka hoʻololiʻana, no ka mea,ʻaʻole e loli nā'āpana o ka paʻakikī.
37.3 Polysolids
Ma waho aʻe o nā kumuhana, hiki iā mākou ke hana i nā mea paʻa i loaʻa mai polyline a i ka hui pū me lākou, ua kapaʻia kēia mau polysolids.
Hiki ke hoʻomaopopoʻia nā polysolids e like me nā mea paʻa i loaʻa mai ka hoʻopukaʻana, me kahi kiʻekiʻe a me ka laulā, laina a me nā'āpana. ʻO ia, e huki wale i kēia laina a me nā'āpae (e like me ka polyline) aʻo Autocad e hoʻololi iā lākou i kahi mea paʻa me kahi'ākea a me ke kiʻekiʻe e hiki ke hoʻonohonohoʻia ma mua o ka hoʻomakaʻana o ka mea. No laila, i waena o kēia mau koho, hiki iā mākou ke kuhikuhi i kahi polyline, a iʻole nā mea'ē aʻe 2D e like me nā laina, nā'āpana, a me nā'ōpili, aʻo kēia mau mea e lilo i mea palekana. E nānā i kekahi mau hiʻohiʻona eʻae iā mākou e hoʻohana i kā lākou koho.
37.4 Nā mea kaulike
Hoʻomumuʻia nā mea kaulike maʻapaʻa me ka hui pūʻana oʻelua mau mea likeʻole o kēlāʻano kēiaʻano: keʻano mua, ka loli, ka hoʻokuʻuʻia, ka hoʻomāmā a me kahi hiki ke kūkuluʻia me nāʻano o nā māhele.
37.4.1'Āina
E like me ka inoa e hōʻike ana, me kēia kauoha e hiki iā mākou keʻokiʻoki i nā mea paʻa ma ka hoʻomaopopoʻana i kaʻilikaiʻiliʻana a me kahi e hoʻohanaʻia ai ka mokulele. Pono kākou e koho inā e hoʻopauʻia kekahi o nāʻaoʻaoʻelua a inā ua mālamaʻiaʻelua. Hōʻike ka papa hōʻike kauoha i nā koho a pau e hiki ai ke ho'ākāka i nā'ōhinu hoʻohālike, aiʻole pehea e hoʻohana ai i nā mea'ē aʻe e ho'ākāka i kēia mau papa.
