Tsim crafts nrog lawv tus kheej tes yog nthuav tsis tsuas yog rau cov me nyuam, tab sis rau cov laus. Txawm li cas los xij, rau cov neeg laus, ib qho qauv zoo ntawm cov qauv tau tsim, uas txawv ntawm qhov nyuaj ntawm qhov kev siv thiab lub sijhawm siv rau lawv qhov kev tsim. Tsis ntev los no, cov laus thiab menyuam yaus muaj kev txaus siab los tsim cov duab cov duab geometric. Rau daim ntawv no ntawm cov nuj nqis yog icosahedron, uas yog ib qho polygon thiab yog ib qhov Platonic khib nyiab - li niaj zaus polyhedra. Daim duab no muaj 20 sab npoo (qhov sib npaug ntawm qhov sib npaug), 30 npoo thiab 12 qhov chaw, uas yog qhov sib txuas ntawm 5 tav. Qhov tseeb icosahedron ntawm daim ntawv yog qhov nyuaj rau kev sib sau ua ke, tab sis nthuav. Yog hais tias koj yog cov ntse heev ntawm origami, ces ua daim ntawv icosahedron nrog koj tus kheej tes yuav tsis yooj yim. Nws yog tsim los ntawm cov ntawv xim dawb, corrugated, ntawv ci, ntim ntawv rau paj. Siv ntau yam ntaub ntawv, koj tuaj yeem muab kev zoo nkauj dua thiab zoo nkauj rau koj cov icosahedron. Txhua yam nyob ntawm lub tswv yim ntawm nws tus creator thiab cov ntaub ntawv muab rau ntawm lub rooj xwb.

Peb muab koj ob peb versions ntawm icosahedron scans uas tau muab luam tawm, muab xa mus rau daim ntawv tuab thiab daim ntawv duab, khoov cov kab thiab ua ke zoo.

Yuav ua li cas ua ib qho icosahedron ntawm daim ntawv:
Yuav kom sib sau ua ib qho icosahedron los ntawm ib daim ntawv los yog xa ntawv, koj yuav tsum npaj cov ntaub ntawv hauv qab no ua ntej:
- mock-up ntawm icosahedron;
- kua nplaum PVA;
- txiab;
- kav.
- Sau tawm ib lub thuam tawm ntawm icosahedron rau ib daim ntawv.
- Txiav nws tawm los ntawm kev cim sau ntawv. Qhov no yog qhov tsim nyog thiaj li muaj qhov chaw pub dawb rau lub nplhaib ua ke. Nws yog ib qho tseem ceeb kom txiav tawm lub icosahedron li qeeb sai li sai tau, vim hais tias nyob rau hauv lub slightest hloov lub cwj pwm yuav nws thiaj li pom npeeb. Qhov no xav tau ntau tshaj yog txiav qhov tseeb tias tag nrho cov vaj tse peb sab hauv icosahedron muaj tib sab, thiab yog tias ib sab yuav txawv sijhawm, qhov kawg xws li qhov tsis sib thooj me me yuav caum koj lub qhov muag.
- Peb quav cov icosahedron nrog cov kab.
- Nrog kev pab los ntawm cov kua nplaum peb cov kua nplaum rau ntawm qhov chaw delineated los ntawm cov kab dashed, thiab txuas rau cov tog sab hauv ntawm cov vajvoos peb sab. Nws yog ib qho tsim nyog yuav tau tuav nyob rau hauv xws li mob txhua tus glued sab rau 20 seconds rau ntau lub ntom fixation. Zoo sib xws, koj yuav tsum nplua tag nrho cov sab ntawm icosahedron. Qhov kawg ntawm ob txoj kab qhua tuaj yeem yog qhov nyuaj tshaj plaws hauv tsevneeg, vim lawv xav tau kev txawj thiab ua siab ntev. Icosaedr yog npaj txhij.
Thaum tsim ib qho icosahedron, nws yog ib qho tseem ceeb uas yuav tsum tau them nyiaj tshwj xeeb rau cov txheej txheem ntawm kev siv tag nrho cov ntsiab lus: thiaj li yuav muab cov ntawv khawm khawm, koj siv tau cov cwj pwm niaj zaus.
Nws yog noteworthy tias icosahedron kuj muaj nyob rau hauv txhua txhua hnub lub neej. Piv txwv li, ncaws pob npas yog ua rau hauv daim ntawv ntawm ib daim duab icosahedron (ib lub hnab polyhedron uas muaj 12 pentagons thiab 20 hooj ntawm cov duab zoo). Qhov no yog qhov tshwj xeeb yog tshwm sim yog tias koj pleev xim rau qhov icosahedron uas tshwm sim dub thiab dawb, zoo li lub npov nws tus kheej.

Xws li ib lub npas tuaj yeem ua nws tus kheej tau luam tawm tau luam tawm ib qho kev luam tawm thawj ntawm cov cim icosahedron hauv 2 phau ntawv luam:
Tsim ib qho icosahedron nrog koj tus kheej tes yog kev nthuav tswv yim uas yuav tsum tau xav txog kev xav, ua siab ntev thiab ntau ntawv. Txawm li cas los xij, cov txiaj ntsim tau los ntawm qhov kawg yuav thov lub qhov muag kom ntev. Tus cim icosahedron tau muab pub rau menyuam yaus yog tias nws twb muaj hnub nyoog peb lawm. Kev ua si nrog cov duab hauv daim duab, nws yuav tsim tsis yog kev xav xwb, kev txawj ntse, tab sis kuj paub txog lub ntiaj teb ntawm geometry. Yog tias ib tus neeg laus txiav txim siab los tsim ib qho icosahedron ntawm nws tus kheej, ces zoo li txheej txheem rau kev tsim ntawm icosahedron yuav tso sij hawm kom dhau mus, thiab tseem khav txog nws txoj kev muaj peev xwm los tsim cov duab xis.
