CAD: txhua yam txog computer-aided design software

CAD

Puas tau txij li thaum cov khoos phis tawm tau siv rau hauv kev lag luam, ib qho ntawm thawj yam uas lawv tau thov ua ntej yog nyob hauv CAD tsim ntawm Cheebtsam. Cov khoos phis tawm tuaj yeem ua tus tsim qauv ntau dua li siv cov txheej txheem sib txawv ntawm lub sijhawm, thiab tseem tso cai hloov kho tus qauv tsim, yooj yim ua cov ntawv luam ntawm tus qauv, thiab lwm yam.

Tam sim no, cov cuab yeej CAD tau hloov ntau heev. Tam sim no cov software muaj ntau dua tiav thiab tso cai rau ua ntau yam dua li txheej txheem CAD txheej thaum ub. Thiab nrog rau cov sij hawm tuaj txog ntawm 3D luam ntawv, cov kev pab cuam no tau dhau los ua tswv yim ntxiv hauv kev lag luam thiab kos duab.

Dab tsi yog CAD?

Excavator tsim CAD software

CAD yog cov ntawv sau rau Computer-Aided Designing, uas yog, siv computer-aided. Ib hom software yuav muaj peev xwm los tsim ntau txoj haujlwm thiab uas yog siv rau hauv cov lag luam sib txawv ntawm kev lag luam, los ntawm kev tsim ntim, mus rau architecture, los ntawm kev tsim qauv ntawm cov tshuab, tshuab, cov qauv ntawm txhua yam, tsheb, ncig, thiab lwm yam. Cov.

Nws kuj tseem siv tau los tsim cov cim thiab siv lawv hauv kev ua yeeb yaj kiab ua yeeb yaj kiab, simulations, thiab lwm yam. Tus software Hnub no lub CAD tau dhau los ua tiav, cia ua ntawv thov muaj ntau heev tshaj dua. Qhov tseeb, cov kev pab cuam tau pib tso cai rau 2D, 3D tsim, daim ntawv thov ntawm cov ntawv sau, cov khoom siv, cov txheej txheem kev teeb tsa, teeb pom kev zoo, txav mus los thiab lwm yam.

Tab sis mus txog rau tam sim no, ntau tau hloov txij thaum pib. Thiab kom pom tias cov keeb kwm koj yuav tsum rov qab mus tus 50s, thaum qee cov kev pabcuam duab pib pib siv ntawm MIT los ua cov ntaub ntawv tau los ntawm cov kab ke radar ntawm North American Air Force. Txoj kev ntawd nws tuaj yeem pom qhov pom tau los ntawm radar ntawm ib tus CRT saib.

Hauv tib lub chaw sim tshuaj no, Lincoln Laboratory, cov hauv paus ntawm lub koos pis tawj uas peb paub niaj hnub no yuav pib nteg. Qhov no yuav tshwm sim hauv 60s, tso cai rau koj siv cov keyboard thiab ib qho cuab yeej los kos cov duab ntawm qhov screen. Hauv txoj kev yuav luag sib luag, lwm cov haujlwm zoo sib xws tau tsim kho hauv cov tuam txhab xws li General Motors, xws li ITEK qhov project, PDP-1 khoos phis tawm nrog lub vijtsam vector nrog lub hard disk refresh nco, nrog rau lub ntsiav tshuaj thiab hluav taws xob cwj mem nkag mus rau cov ntaub ntawv Cov.

Los ntawm me me los ntawm cov kab ke tau txhim kho, los rau tom bds (Cov lus piav qhia txog Lub Tsev Lub Tsev Kawm los ntawm Charles Eastman, tus xibfwb ntawm Carnegie Mellon University. Nws yog lub tsev qiv ntawv lossis lub hauv paus nrog cov qauv txheej txheem yooj yim uas tuaj yeem sib sau los tsim ntau cov qauv txheej txheem nyuaj.

Cov txheej txheem raws li ITEK tau pib ua lag luam nyob rau xyoo 1965, yog thawj qhov system Kev Lag Luam CAD Nws tau siv li 500.000 Asmeskas las thaum lub sijhawm. Ob peb xyoos tom qab, aerospace thiab automotive tuam txhab xws li General Motors, Chrysler, Ford, thiab lwm yam, tau pib siv thawj lub tshuab CAD los tsim lawv cov khoom.

Tsis ntev tom qab thawj kab yuav los txog CAD / CAM (Kev Tsim Kho Khoom Siv Computer (Computer-Aided), uas yog, CAD tsim ua ke nrog kev tsim khoom siv los tsim cov khoom tsim hauv CAD. Nws yuav siv txoj hauv kev tho kev ua ntej los ntawm Lockheed, lub tuam txhab ntawm cov tshuab huab cua.

CAD cov tshuab los ntawm xyoo 70s tso rau hauv nqe mus rau $ 130.000, tab sis tseem kim heev. Nws yuav tsis tau kom txog thaum lub 80s thaum pheej yig dua CAD software pib siv, ua ke nrog lub hauv paus tsim ntawm AutoCAD (Autodesk) nyob rau xyoo 1982. John Walker lub tuam txhab tau txiav txim siab kev lag luam txij li hnub, muab software rau tsawg dua $ 1000 thiab ua rau nws siv ntau dua thiab siv.

Hauv 90s, CAD cov tshuab pib kov yeej lwm lub platform (dhau li ntawm Sun Microsystems workstations, Digital Equipment, thiab lwm yam) ntawm cov khoos phis tawj tsis tshua kim, mus txog Microsoft Windows thiab PCCov. Txij lub sijhawm ntawd, hom software no tau txuas ntxiv hloov zuj zus thiab txo tus nqi, txawm tias muaj ntau ntau cov haujlwm pub dawb thiab pub dawb tau tshwm sim ...

CAD cov kev pab zoo tshaj plaws

Yog koj xav paub txog CAD tsim software uas koj tuaj yeem siv hnub no, ntawm no yog qhov kev xaiv zoo ntawm lawv. Thiab txawm hais tias muaj qee qhov tseem ceeb thiab siv dav hauv kev lag luam xws li Autodesk AutoCAD, vim tias nws yog blog kho vajtse dawb, peb tseem yuav tsom mus rau software dawb:

3D luam ntawv software

3D lub luam ntawv

Tam sim no, yog tias koj xav paub txog cov kev pabcuam twg yog siv los tsim cov khoom siv thiab tom qab ntawd luam tawm ntawm lawv lub tshuab luam ntawv 3D, tom qab ntawd koj yuav tsum muaj qee qhov kev pabcuam uas koj tuaj yeem siv rau qhov ntawd. Kuv twb hais txog ib ntawm lawv ua ntu lus dhau los, vim nws yog FreeCAD. Dhau li ntawd, koj kuj tseem muaj lwm yam pub dawb lossis qhib qhov kev xaiv xws li:

  • Tsim Tsim Txim Mechanical- yog dawb CAD software tsim los ntawm RS Cheebtsam thiab SpaceClaim Corporation. Qhov project no tau tsim tshwj xeeb rau kev siv thiab rau kev tsim qauv 3D. Ntxiv rau qhov no, nws yooj yim heev rau siv, nrog lub qab ntxiag graphical interface haum rau cov neeg siv qib nruab nrab.  download.
  • Txawj kos- Nws muaj qhov kev ua tau yooj yim heev dawb uas tau txais qhov muaj koob npe vim nws tso cai rau kev kos duab ceev thiab muaj kev thov zoo hauv kev tsim qauv kos duab. Nws lub vev xaib yog lub vev xaib, yog li nws tuaj yeem siv tau los ntawm ntau lub tshuab, tso cai rau export rau STL rau 3D tshuab luam ntawv. Kev nkag.
  • TinkerCAD: Nws tseem muaj qhov Web site pub dawb los kos cov me me yooj yim hauv 3D. Dav dav siv hauv kev kawm vim nws cov yam ntxwv, muaj peev xwm siv nrog cov thawj coj, xws li cov thawv, kheej, lub tog raj kheej, thiab lwm yam, kom muaj peev xwm sib koom ua ke, tig thiab tso lawv los tsim cov duab ntau dua. Tau kawg koj tuaj yeem xa cov qauv mus rau STL rau 3D luam ntawv. Kev nkag.

Cov ntsiab lus ntawm tsab xov xwm ua raws li peb cov ntsiab cai ntawm kev tswj hwm kev ncaj nceesCov. Tshaj tawm ib qho yuam kev nyem no.
