Cov ntaub ntawv 3D Digital tau hloov txoj kev engineers ua hauj lwm nrog manufacturers.Cov engineers tam sim no tuaj yeem tsim ib feem siv CAD software, xa cov ntaub ntawv digital mus rau cov chaw tsim khoom, thiab kom cov chaw tsim khoom ua ib feem ncaj qha los ntawm cov ntaub ntawv siv cov txheej txheem tsim digital xws liCNC machining.

Tab sis txawm hais tias cov ntaub ntawv digital tau ua kev tsim khoom sai thiab yooj yim dua, lawv tsis tau hloov tag nrho cov duab kos duab, piv txwv li kev tsim cov ncauj lus kom ntxaws, annotated engineering drawings.Cov duab 2D no yuav zoo li qub piv rau CAD, tab sis lawv tseem yog ib txoj hauv kev tseem ceeb los muab cov ntaub ntawv hais txog kev tsim ib feem - tshwj xeeb tshaj yog cov ntaub ntawv uas CAD cov ntaub ntawv tsis tuaj yeem xa tau yooj yim.

Kab lus no saib cov hauv paus ntawm 2D kos duab hauv engineering: lawv yog dab tsi, lawv ua haujlwm li cas nrog rau cov qauv 3D, thiab vim li cas koj tseem yuav tsum xa lawv mus rau lub tuam txhab tsim khoom nrog rau koj cov ntaub ntawv CAD.

Dab tsi yog 2D kos duab?

Nyob rau hauv lub ntiaj teb no ntawm engineering, ib tug 2D daim duab los yog engineering kos duab yog ib hom kev kos duab uas qhia cov ntaub ntawv hais txog ib feem, xws li nws geometry, qhov ntev, thiab kam rau ua.

Tsis zoo li cov ntaub ntawv CAD digital, uas sawv cev rau qhov tsis tau tsim nyob rau hauv peb qhov ntev, ib qho kev kos duab kos duab sawv cev rau ib feem ntawm ob qhov ntev.Tab sis cov kev pom ob sab no tsuas yog ib qho ntawm 2D kev kos duab.Dhau li ntawm ib feem geometry, ib daim duab kos yuav muaj cov ntaub ntawv ntau yam xws li qhov ntev thiab qhov ntev, thiab cov ntaub ntawv zoo xws li cov khoom siv thiab cov khoom tiav.

Feem ntau, tus kws sau ntawv lossis tus kws tsim qauv yuav xa cov duab 2D, txhua qhov uas qhia txog qhov sib txawv los yog lub kaum ntse ntse.(Qee qhov 2D kos duab yuav yog cov ncauj lus kom ntxaws txog cov yam ntxwv tshwj xeeb.) Kev sib raug zoo ntawm ntau cov duab kos feem ntau yog piav qhia los ntawm kev kos duab sib dhos.Standard views muaj xws li:

Kev lig kev cai, 2D kos duab tau ua manually siv cov khoom siv kos duab, piv txwv li lub rooj sau ntawv, xaum, thiab cov cuab yeej siv kos duab kos duab zoo meej thiab nkhaus.Tab sis niaj hnub no 2D kos duab kuj tuaj yeem tsim siv CAD software.Ib daim ntawv thov nrov yog Autodesk AutoCAD, ib daim ntawm 2D kos duab software uas kwv yees cov txheej txheem sau ntawv.Thiab nws tseem tuaj yeem ua kom tau txais 2D kos duab los ntawm 3D qauv siv CAD software xws li SolidWorks lossis Autodesk Inventor.

2D kos duab thiab 3D qauv

Vim tias cov qauv 3D digital yuav tsum xa cov duab thiab qhov ntev ntawm ib feem, nws yuav zoo li 2D kos duab tsis tsim nyog.Hauv qee qhov kev txiav txim siab, qhov tseeb yog: tus kws tshaj lij tuaj yeem tsim ib feem siv CAD software, thiab cov ntaub ntawv digital tib yam tuaj yeem xa mus rau ib lub tshuab rau kev tsim khoom, tsis muaj leej twg tuaj tos ib tug cwj mem.

Txawm li cas los xij, qhov ntawd tsis qhia tag nrho zaj dab neeg, thiab ntau tus neeg tsim khoom txaus siab tau txais 2D kos duab nrog rau CAD cov ntaub ntawv thaum ua cov khoom rau cov neeg siv khoom.2D kos duab ua raws li cov qauv thoob ntiaj teb.Lawv nyeem tau yooj yim, tuaj yeem ua haujlwm hauv ntau qhov chaw (tsis zoo li lub khoos phis tawj lub vijtsam), thiab tuaj yeem hais meej meej txog qhov tseem ceeb thiab qhov ntev.Nyob rau hauv luv luv, manufacturers tseem hais cov lus ntawm 2D technical drawings.

Tau kawg, cov qauv 3D digital tuaj yeem ua tau ntau qhov kev nqa hnyav, thiab 2D kos duab yog qhov tsim nyog tsawg dua li lawv ib zaug.Tab sis qhov no yog qhov zoo, vim tias nws tso cai rau cov kws tsim khoom siv 2D kos duab feem ntau rau kev xa cov ntaub ntawv tseem ceeb tshaj plaws lossis tsis zoo: cov lus qhia tshwj xeeb uas yuav tsis meej tam sim ntawm CAD cov ntaub ntawv.

Hauv cov ntsiab lus, 2D kos duab yuav tsum tau siv los ua kom tiav cov ntaub ntawv CAD.Los ntawm kev tsim ob qho tib si, koj muab cov tuam txhab tsim cov duab meej tshaj plaws ntawm koj cov kev xav tau, txo qhov tshwm sim ntawm kev sib txuas lus tsis zoo.

Vim li cas 2D kos duab yog qhov tseem ceeb

Muaj ntau qhov laj thawj vim li cas 2D kos duab tseem yog ib feem tseem ceeb ntawm kev tsim khoom.Nov yog qee qhov ntawm lawv:

Cov yam ntxwv tseem ceeb: Cov neeg siv kos duab tuaj yeem qhia cov ntaub ntawv tseem ceeb ntawm 2D kos duab kom cov tuam txhab tsis hla ib qho tseem ceeb lossis nkag siab yuam kev rau qhov tsis meej meej tshwj xeeb.

Portability: Luam tawm 2D kev kos duab tuaj yeem txav tau yooj yim, sib koom, thiab nyeem hauv ntau qhov chaw.Kev saib tus qauv 3D ntawm lub vijtsam computer yog qhov muaj txiaj ntsig zoo rau cov tuam txhab, tab sis yuav tsis muaj lub monitor nyob ib sab ntawm txhua qhov chaw machining lossis chaw ua haujlwm tom qab.

Kev paub: Txawm hais tias txhua tus neeg tsim khoom paub txog CAD, muaj qhov sib txawv ntawm cov qauv digital sib txawv.Drafting yog ib qho txheej txheem tsim, thiab cov qauv thiab cov cim siv ntawm 2D kos duab yog pom tau los ntawm txhua tus hauv kev lag luam.Tsis tas li ntawd, qee cov tuam txhab lag luam tuaj yeem ntsuas 2D daim duab - txhawm rau kwv yees nws cov nqi rau kev tsocai, piv txwv li - sai dua li lawv tuaj yeem ntsuas tus qauv digital.

Cov Lus Ceeb Toom: Cov kws ua haujlwm yuav sim suav tag nrho cov ntaub ntawv ntsig txog ntawm 2D daim duab, tab sis cov tuam ntxhab, cov tshuab tshuab, thiab lwm tus kws tshaj lij yuav xav sau cov qauv tsim nrog lawv tus kheej sau ntawv.Qhov no yog ua kom yooj yim nrog kev luam 2D ​​daim duab.

Kev Tshawb Fawb: Los ntawm kev xa 2D cov duab kos uas sib haum rau 3D qauv, cov chaw tsim khoom tuaj yeem tso siab tau tias cov ntawv teev geometries thiab qhov ntev tsis tau sau tsis raug.

Cov ntaub ntawv ntxiv: Niaj hnub no, CAD cov ntaub ntawv muaj cov ntaub ntawv ntau dua li cov duab 3D nkaus xwb;nws tuaj yeem teev cov ntaub ntawv xws li kam rau ua thiab xaiv cov khoom siv.Txawm li cas los xij, qee yam tau yooj yim sib txuas lus hauv cov lus nrog rau 2D daim duab.
