Yog tias koj txiav txim siab los kawm CAD ntawm koj tus kheej, ces ib nrab ntawm qhov kev vam meej twb tiav lawm. Tus so yog tswj hwm qhov kev txiav txim siab no, nkag siab txog CAD kos duab software thiab cov txheej txheem ua haujlwm, thiab tom qab ntawd xyaum, xyaum, thiab xyaum. Niaj hnub no, kuv xav qhia rau koj thawj 21 cov ntaub ntawv ntawm CAD cov ntaub ntawv kawm tus kheej, vam tias yuav pab cov phooj ywg uas tsis paub yuav pib kawm tus kheej CAD li cas.
1. Cov cuab yeej kab (tus yuam sij luv L, cov ntaub ntawv tsis txaus ntseeg). Thaum kos ib txoj kab ncaj nraim, yog tias koj ua raws qhov ntev ntxiv lub kaum sab xis, tom qab nkag mus rau qhov ntev, nias lub tab khawm hloov
2. Kev siv lub khawm nruab nrab nas hauv CAD: "Zoom hauv thiab tawm", "Nias thiab tuav lub khawm nruab nrab nas kom txav", "ob zaug nias lub khawm nruab nrab nas", tag nrho cov duab hauv cheeb tsam kos duab tuaj yeem pom. Rau cov duab uas tshaj tus ncej loj, koj tuaj yeem nias lub pob nas nruab nrab ob zaug kom pom lawv tag.
duab
3. Rho tawm cov cuab yeej: "Xaiv cov khoom yuav tsum tau muab tshem tawm, thiab tom qab ntawd nias lub Delete", siv cov cuab yeej rho tawm shortcut key E
4. Polar coordinates: Nkag mus rau polar coordinates, nkag mus rau qhov deb thiab lub kaum sab xis, sib cais los ntawm lub kaum sab xis, piv txwv li:
Txhawm rau qhia qhov taw tes ntawm lub kaum sab xis ntawm 45 degrees, ib chav nyob ntawm qhov taw tes dhau los, nkag mus rau 1<45.
Los ntawm lub neej ntawd, lub kaum sab xis nce nyob rau hauv lub counterclockwise kev taw qhia thiab txo nyob rau hauv lub clockwise kev taw qhia. Yog tias koj xav txav mus rau hauv txoj kev coj ua clockwise, koj yuav tsum nkag mus rau qhov tsis zoo ntawm lub kaum sab xis.
Koj tuaj yeem siv UNITES cov lus txib kom sau lub kaum sab xis ntawm daim duab tam sim no.
5. Kev tsim kab: shortcut key XL
6. Kev xaiv CAD:
a, xaiv los ntawm sab laug mus rau sab xis, koj yuav tsum ua kom tiav nws los xaiv
b, xaiv los ntawm sab xis mus rau sab laug, kov tuaj yeem xaiv
C, nyem
7. Ray: shortcut key RAY
8. Arc: shortcut key A/ARC
duab
9. Polyline: shortcut key PL
Lus Cim: Polylines tuaj yeem tsis tsuas yog kos cov kab ncaj nraim, tab sis kuj kos arcs, thiab txheej ntawm ib nrab-dav thiab dav tuaj yeem kos cov xub.
10. Vajvoog: shortcut key C
11. Trim tool shortcut key TR Feem ntau siv yog TR-Space-Xaiv Object rau Trim" Qee lub sij hawm cov khoom uas tsis tuaj yeem txiav tuaj yeem xaiv tau thiab muab tshem tawm.
Nco tseg: Tuav cia ua haujlwm kom ncua qhov khoom.
12. Drawing txoj cai: thawj txoj hauj lwm, ces zoo li.
13. Ellipse shortcut key EL
14. Offset hais kom luv tus yuam sij O
Yuav siv li cas: xaiv qhov offset hais kom ua - nkag mus rau qhov offset nrug - xaiv cov khoom yuav tsum tau offset - qhia qhov kev taw qhia offset (rau sab twg rau offset)
15. Tus yuam sij shortcut F rau lub kaum sab xis kuj tseem siv tau los ua cov ces kaum sib npaug nrog tangent thiab tangent vojvoog vojvoog, thiab tsuas yog rho tawm cov khoom seem.
16. Tus yuam sij shortcut rau kev luam cov kev sib hloov cov lus txib yog CO, thiab koj tuaj yeem siv Ctrl ntxiv rau C (qhov kev taw qhia ntawm daim duab tom qab luam ntawv tseem tsis hloov)
Nco tseg: qhov theej lub hauv paus taw tes yog taw tes hauv daim duab theej
Tus yuam sij shortcut rau kev sib hloov yog RO,
Nco tseg: Qhov taw tes tig yog qhov chaw xaiv qhov chaw, thiab cov duab tig ib ncig ntawm qhov taw tes, uas tsis nyob hauv cov duab xaiv.
17. Daim iav duab hais kom ua: shortcut key MI Thaum ob yam khoom muaj tib lub duab thiab sib luag txog ib kab, koj tuaj yeem siv daim iav duab hais kom ua.
18. Daim duab plaub lub cuab yeej shortcut tseem ceeb REC
19. Daim duab kos duab code ntawm daim duab ncej
duab
20. Decompose tus yuam sij shortcut X (decompose tag nrho rau hauv ntau qhov chaw). Piv txwv li, thaum kos tus ncej puab ntawm daim duab thav duab, ua ntej decompose cov txheej txheem, thiab ces offset lub decomposed ncaj kab los ntawm ib qho kev ncua deb kom tau lub puab ncej.
21. Lub spline nkhaus shortcut key SPL yog siv los qhia qhov tawg ntawm qhov tawg lossis qhia qhov uas yuav tsum tau muab tshem tawm.
