Ke kūkulu i nā meaʻimi me AutoCAD - Paukū 2

MOKUNA 6: NĀ KUMU I KE AINA

Ke kāhea nei mākou i "mea hana" i kēlā mau mea e hiki ai iā mākou ke huki i Autocad akā uaʻoi aku ka paʻakikī ma mua o ka nānāʻiaʻana o nā mea maʻalahi ma nā paukū o ka mokuna mua. I mea, ia mea mea mea, ma kekahi hihia, hiki ke hoakakaia like me ka hoʻohui pū 'ia o ka poe noonoo ole mea, no ka mea, o ko lakou anahonua mea he huihui' ana o ia mau kumu mua anahonua. I kekahi mau kumu'ē aʻe, e like me nā kiko'ī, he mea pili lākou me kā lākou iho mau palena. Kekahi ala e, i nāʻano o nā 'ikamu mākou nānā'ʻaneʻi (polylines, splines, nā kui nao, Kauai, ao, wahi a me kaʻaoʻao pale), wawahi i aneane kekahi hoʻokau 'no e pili ana' ano apau loa i mea mea mea.

6.1 Polylines

ʻO nā polyline nā mea i hanaʻia e nā lālā line, arcs, aiʻole nā ​​hui o nā meaʻelua. A me ko mākou ke kauo laina, a kuokoa arcs ua like ho omaka me ka hopeʻoi o kekahi laina a piʻo, a hiki i ka hana ia pepa, polylines i ka mea pono i nā mea a pau Hoʻohana i kuahene hana naʻauao me he hookahi mea . Pela, ua pinepine hihia kahi i mea e ahoʻia e hana i kekahi polyline Hoʻohana o ka laina a me arcs kuokoa, o ka oi aku ia oe i ke e mākaʻi kiaʻi, mea ka hiki pono o ka hoʻoponopono i loli ma ka hookahi mea i loko o kekahi mau. ʻO kekahi pāʻoihana'ē aʻe, hiki iā mākou ke ho'ākāka i kaʻeleʻele mua a hope loa no kekahi māhele o ka polyline a laila hou hou i kēia mānoanoa no ka māhele aʻe. Eia hou, o ka hana ana o polylines e hooiaio ana i ka hookuiia o ka helu mua o kahi segment line or arc i ka pauku mua. Kēia hui e hana i kekahi o na vertices o polyline, a hiki i ka wa a ke hoʻololi 'ana i kona' ole ka hāʻuleʻana (i kūkākūkā ma lalo nei), i ka pilina ma waena o nā Hoʻohana i koe i pololei ia, hiki paa, e kāinoa paʻa contours, i mea likeʻole pono e mahalo ma hope aku: keʻike mākou i nāʻaoʻao ma kēia mokuna like a me ka wā e aʻo ai mākou i ka paʻiʻia o nā mea a me ka uhi.
E like me nā polyline nā māhele o nā laina a me nā'āpana, nā koho like e hāʻawi iā mākou e ho'ākāka i nā palena iʻike muaʻia e hana i nā laina a iʻole nā'āpau i loko o kēlā me kēia. Ke hoʻokō mākou i ke kauoha e hana polyline, nīnau maiʻo Autocad iā mākou no ka helu mua, mai laila e hiki iā mākou ke hoʻoholo inā he laina a iʻole kahi arc ka māhele mua a no laila, e kuhikuhi i nā palena kūpono e huki ai.

I ka manawa a mākou i unuhi ai iʻelua mau'āpana, ma waena o nā koho o ka laina kauoha ke pani i ka polyline,ʻo ia hoʻi, e hoʻohui i ka peʻa hope loa me ka mea mua. Hoʻopiliʻia ka polyline me kahi arc a laina paha e pili ana i keʻano o ka hope hope loa i unuhiʻia, akā naʻe ua maopopo he mea ponoʻole ke pani i ka polyline. ʻO ka hope, e noʻonoʻo hiki hiki ke hoʻololi i kaʻeleʻele mua a me ka hope o kēlā me kēia māhele o ka polyline, me ka hoʻonuiʻana i ka hana i ka hanaʻana i nāʻano.
