Txhua lub tsev kawm txuj ci thiab cov tsev kawm txuj ci muaj cov kev kawm uas cuam tshuam txog kev kos duab. Kev piav qhia geometry thiab engineering graphics yog cov ua tiav ntawm ob lub tsev kawm ntawv kev qhuab qhia: kos duab thiab geometry. Tag nrho cov kev tshawb fawb no yog inextricably txuas. Tab sis, txawm li cas los xij, txhua qhov chaw muaj nws tus kheej cov cai, cov kev pab cuam thiab cov kev kawm.
Cov cuab yeej xav tau
Hmoov tsis zoo, tsis yog txhua lub tsev kawm ntawv thiab cov tsev kawm txuj ci muaj kev kos duab. Nws yuav nyuaj dua rau cov tub ntxhais kawm kom paub txog engineering graphics, tab sis yog tias lawv xav tau, lawv tuaj yeem ntes tau. Vim li cas nws tau hais saum toj no txog geometry? Nws yog ib qho tsim nyog thaum kawm cov duab, rau kev tsim kho, kev txheeb xyuas. Koj tuaj yeem kwv yees li cas yam tsis muaj geometry tias lub kaum sab xis ntawm lub nqaj yog 45 degrees? Los yog lub kaum sab xis yog dab tsi? Kev kos duab ntawm engineering graphics tsis ua tiav yam tsis muaj cov cuab yeej tsim nyog. Feem ntau muaj polygons, cones, spheres thiab lwm yam duab los ntawm geometry.
Koj xav tau lub peev xwm los siv tus pas ntsuas thiab xaum, nrog rau lub ntsuas phoo, tus neeg saib xyuas, lub xwmfab thiab tus thawj coj saib xyuasyog tias tsim nyog. Cov duab geometry thiab engineering graphics xav kom koj muaj txhua yam koj xav tau nrog koj. Nws raug nquahu kom coj mus rau hauv tus account tias cov kab khoom ntawm cov duab tau nthuav tawm nrog ib tus cwj mem nrog tuab tuab. Txhua tus tub ntxhais kawm yuav tsum tsis txhob hnov qab nqa cov cwj mem yooj yooj yim nrog nws rau cov kev qhuab qhia zoo li no, nco ntsoov coj cov cwj mem xim, vim hais tias nyob rau hauv cov lus piav qhia geometry qee cov haujlwm nyuaj yuav tsum xaiv cov xim sib txawv ntawm cov kab. Lub lwv yuav tsum muab tso rau ib sab ntawm cov xaum ua ntej kom tsis txhob hnov qab.
piav txog geometry thiab cov tub ntxhais kawm tsis to taub
Nyob rau hauv thawj xyoo nyob rau hauv thawj lub semester ntawm cov kev tshwj xeeb, tag nrho cov xib fwb thiab cov tub ntxhais kawm ntsib teeb meem. Rau qee qhov laj thawj, yuav luag 90% ntawm cov tub ntxhais kawm los ntawm cov kwj deg tsis tuaj yeem nkag siab txog kev tshawb fawb no. Zoo li lawv muaj qee qhov txawv txav: dab tsi thiab qhov twg los ntawm, txoj kab no tau tsim li cas?
Ntau tus kws qhia ntawv sim ua kom pom cov teeb meem tsis yog ntawm lub rooj tsavxwm nkaus xwb, tab sis kuj muaj tiag. Piv txwv li, lawv yuav khaws lub pyramid thiab hais kom cov tub ntxhais kawm hais tias cov ntsiab lus ntawm lub pyramid yuav ua li cas rau ntawm lub rooj tsavxwm. Ib lo lus "projected" twb pib ntshai cov neeg mloog. Qhov tseeb, txhua yam yog yooj yim heev. Hauv cov ntsiab lus yooj yim, koj yuav tsum tau kos cov ces kaum ntawm lub pyramid ntawm lub rooj tsavxwm nrog cov dots thiab kos kab uas coj los ntawm lub pyramid mus rau saum npoo ntawm lub rooj tsavxwm. Kev piav qhia geometry thiab cov duab kos duab engineering sib txawv heev ntawm kev paub los ntawm cov tub ntxhais kawm. Kev qhuab ntuas thib ob yooj yim dua.
Pab tub kawm li cas? Nws yuav tsum raug qhia kom nthuav tawm cov khoom. Piv txwv li, cia peb uaopaque kav thiab square. Tus kav yuav nyob rau sab laug tes yuav luag ntawm lub qhov muag, thiab lub square ntawm lub rooj. Nws pom dab tsi? Ib feem ntawm lub square lub cev ua tsis pom. Yog li, hauv daim duab kos, koj yuav tsum kos cov kab tsis pom nrog ib kab dotted.
Engineering duab thiab nws cov yam ntxwv
Cov neeg uas tau sau ntawv yuav kawm xyaum xyaum tsis muaj dab tsi tshiab. Kev kos duab cov ntsiab lus yog qhov nthuav ntau dua li kev kos duab thiab lawv qhov projections ntawm qhov chaw. Raws li txoj cai, nyob rau hauv lub semester thib ob, lub unloved descriptive geometry yog hloov los ntawm engineering thiab computer graphics. Cov tub ntxhais kawm zoo siab.
Ntawm no koj yuav tsum ua siab ntev, thiab tseem ceeb heev kom muaj kev mob siab rau. Nws tsis yog yooj yim los kos cov ntsiab lus kom raug thiab tib lub sijhawm kom raug nws. Thiab txhawm rau txhawm rau txhim kho qhov ntev, kev tsim qauv, tso cov cim hauv daim duab kos duab, ua txhua yam raws li GOST, koj yuav tsum siv phau ntawv siv thiab phau ntawv.
Engineering computer graphics - qhov no yog qhov nyiam cov tub ntxhais kawm. Nws yog qhov yooj yim dua los ua cov duab kos hauv qhov chaw virtual thiab luam tawm ntawm lub plotter hauv lub computer center dua li ua nrog daim ntawv loj loj thiab ntau qhov chaw dawb.
Nws yog ib qho tseem ceeb heev kom ua tiav qhov kev xeem lossis kev xeem kom kawm tsis yog cov ntaub ntawv tseem ceeb xwb, tab sis kuj muaj cov kev kawm. Dab tsi raws nraim? "Compass", "AutoCad", "ArchiCad" thiab lwm yam. Txhua yam nyob ntawm qhov profile ntawm lub tsev kawm ntawv thiab qhov kev zov me nyuam.
Engineering graphics thiab nyiaj tau los
Tam sim no, muaj ntau qhov chaw ua haujlwm hauv Is Taws Nem uas xav tau cov kws tshaj lij nrog kev paub"AutoCAD", "Compass" lossis "Archikada". Cov hauj lwm muaj peev xwm muab tau ob qho tib si hauv chaw ua haujlwm thiab nyob deb.
Yog li ntawd, txhua tus neeg uas xav tau cov nyiaj hli zoo rau cov haujlwm yuav tsum ua tib zoo kawm txog cov kev qhuab qhia xws li piav qhia txog geometry thiab engineering graphics. Los ntawm qhov kev xaiv thib ob ntawm cov nyiaj tau los yog txiav txim siab. Nrog thawj, koj tuaj yeem khwv tau nyiaj los ntawm kev qhia cov tub ntxhais kawm hauv tsev lossis hauv tsev kawm qib siab.
