Koj tuaj yeem ua tus qauv ntawm tetrahedron los ntawm ntau cov ntaub ntawv. Ib qho ntawm cov kev xaiv pheej yig tshaj plaws yog nplaum nws tawm ntawm daim ntawv. Hauv qhov no, kua nplaum tsis tas li, vim daim ntawv nplaum nws tus kheej kuj tsim nyog rau cov hom phiaj no.
Nws yog qhov tsim nyog
- - daim ntawv rau tsim lub scan;
- - ntawv rau qauv;
- - tus pas ntsuas;
- - xaum;
- - tus tawm tsam;
- - txiab;
- - khoos phis tawm nrog AutoCAD.
Cov Lus Qhia
Kauj ruam 1
Pib los ntawm kev tsim ib lub tiaj tus qauv. Yog hais tias koj yuav mus nplaum lub tetrahedron los ntawm cov ntawv tuab tuab, koj tuaj yeem ua lub scan ncaj qha rau nws. Rau cov ntawv ua los ntawm tus kheej, nws yog qhov zoo dua los kos qauv, raws li nws tau ua hauv cov qauv zoo nkauj. Koj tseem tuaj yeem siv lub khoos phis tawm nrog AutoCAD lossis lwm daim duab khoos phis tawm uas tso cai rau koj los tsim cov kev sib thab sib luag.
Kauj ruam 2
Tsim kom muaj vaj huam sib luag sib npaug. Yog tias koj ua qhov no ntawm daim ntawv, tom qab ntawd kos ib txoj kab ntu sib npaug rau ntawm ntug ntawm tetrahedron. Siv tus qauv tiv thaiv txhawm rau txhawm rau 60 ° kaum ntawm qhov kawg. Kos kab ncaj nraim los ntawm cov ntsiab lus tau txais kom txog thaum lawv sib tshuam.
Kauj ruam 3
Ntawm txhua sab ntawm daim duab peb sab uas twb muaj lawm, tsim kho kom zoo ib yam. Ib sab ntawm daim duab peb sab yuav kuj yog ib sab ntawm lwm qhov. Nyob rau hauv tib txoj kev, teem ib sab rau ntawm 60 ° los ntawm qhov xaus ntawm ntu, tab sis nyob rau hauv cov kev taw qhia los ntawm cov twb kos duab. Kos cov kab ncaj nraim hauv cov ntsiab lus tau txog thaum lawv sib tshuam. Koj yuav tsum muaj tus qauv ntawm plaub lub vajvoog sib npaug.
Kauj ruam 4
Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txuas ua ke, muab nyiaj rau peb daim duab peb sab. Ntxiv 1 cm rau ib sab raws nws tag nrho ntev. Tig lub nrawm nrawm sab nraud thiab ua cov nyiaj uas tau txais rau lwm lub ntsej muag, thiab tom qab ntawd rau zaum peb. Txiav tawm cov qauv tiaj tus. Yog tias tsim nyog, taug nws qab rau lwm daim ntawv.
Kauj ruam 5
Khoov tus qauv ncaj nraim rau txhua kab kom koj muaj khoom siv hauv. Quav nyiaj rau sab hauv. Luas fab yog tsim nyog. Siv kua nplaum rau kev sib tshooj thiab nias lawv tawm tsam sab hauv ntawm cov ntsej muag uas nyob ib sab, ua kom cov kab ntawm daim duab peb sab thiab sib tshooj nrog sab dawb ntawm daim duab peb sab. Yog tias cov tetrahedron ua los ntawm daim ntawv ua los ntawm tus kheej, nws yog qhov zoo dua rau khawb txoj kab, tom qab khoov cov duab thiab nias qhov peev xwm rau ntug.
