Kujambula kwa 3D ndi AutoCAD - Gawo 8

Onani 34.1.5

Ndi batani la "View", UCS imagwiritsa ntchito poyambira pomwe ili nayo, koma imawongoleranso nkhwangwa zake mpaka zitalumikizidwa pazenera. Ndiko kuti, X kumanja, Y mmwamba, ndi Z kwa inu, mosasamala kanthu za udindo wa chitsanzo, kotero ndege ya XY, kapena ndege ina iliyonse, sizingafanane ndi nkhope iliyonse pa chitsanzo chanu, pokhapokha mutagwiritsa ntchito mawonekedwe a orthogonal. .

34.1.6 Kusuntha shafts

Ngati mfundo yoyambira ya SCP ndi yolondola pazolinga zake, koma osati momwe ma axele ake, mutha kuzungulira molemekeza aliyense wa iwo. Kuti muchite izi, Gawo la Coordinates la tsamba la View la riboni lili ndi batani pamzere uliwonse.
Kuti tidziwe komwe ma angles amazungulira pa axis yosankhidwa ali abwino, titha kugwiritsa ntchito "Right Hand Rule", yomwe imakhala ndi kuloza chala chachikulu cha dzanja lanu lamanja kumbali yabwino ya axis yomwe idanenedwa. Mwa kutseka zala zanu padzanja lanu mudzadziwa njira yabwino yozungulira. Lamuloli sililephera.
Tiyeni tiwone chitsanzo chotsatira pomwe njira yolowera ma ax ndi X ndi Y ili yolakwika pazolinga zomwe mukutsatira, ndiye kuti muyenera kutsatira lamulo lamanja kumanzere a Z, kotero chala chanu chikuyenera kuloza. Mukatseka zala zanu m'manja mwanu mutha kuwona bwino mbali yomwe mukutembenuzira, yomwe, yomwe simuyenera kuiwala, ndi anti-ola ngati mutayang'ana pa ndege ya XY.

34.1.7 Lamulo la SCP

Lamulo la SCP lidapereka chidule pamwambapa kusankha chimodzi. Itha kupulumutsidwa kuchokera kubatani pagawo lomwe tikuphunzira, kapena titha kulemba SCP mwachindunji pazenera lawalamulira. Chokhacho chomwe tikuyenera kuwunikira apa ndikuti titha kuwona njira zina kutiapangire SCP yathu pazosankha zomwe zimawonekera pazenera.

Magulu a 34.1.8 a chizindikiro cha SCP

Kuphatikiza kwaposachedwa kwa Autocad pakapangidwe kaokha ka Coordrate Systems ndikugwiritsa ntchito zopindika pazithunzi za SCP zokha. Mukadina, muwona mawonekedwe a 4, imodzi mwanjira yomwe ingatipatse mwayi kuti tisunthire pomwepo pomwe pali chidziwitso kwa wina aliyense pazenera, kukhala wokhoza kugwiritsa ntchito, zo, kuzungulira zinthu. Mphete zina zitatuzo zili kumapeto kwa nkhwangwa iliyonse, titha kuzitenga ndi chowunika ndikusintha njira. Mwachiwonekere, momwe ax ax ya Z izikhala yofananira nthawi zonse ndi ndege ya XY, monga momwe ax ax ya X imakhalira nthawi zonse pamagetsi a YZ ndi cholowera cha Y kupita ku ndege ya XZ, mukasintha njira yolowera mbali iliyonse, zotsalazo zimayenda motsatana.
Pomaliza, mukaloza ndi mbewa iliyonse yazithunzi za SCP, muwona mndandanda wazomwe zikugwirizana ndi izi, popeza ndizogwiritsa ntchito zambiri, monga momwe tidaphunzirira mu gawo la 19.2.
