Lub koom haum ntawm kos duab nrog AutoCAD - Seem 5

22.2 Layers thiab khoom

Yog tias qhov kev npaj ntawm peb cov duab kos yog tam sim no raws li lawv lub koom haum los ntawm cov txheej, ces peb yuav tsum paub tias lawv tswj lawv li cas thiab cov txiaj ntsim zoo li cas thaum lawv tsim khoom.
Piv txwv li, yog tias peb txiav txim siab tias ib yam khoom uas twb twv dhau los lawm yuav tsum zwm rau lwm txheej, ces peb xaiv nws thiab xaiv nws cov txheej tshiab ntawm daim ntawv teev lus nyob rau hauv seem ntawm txoj cai. Thaum hloov khaubncaws sab nraud povtseg, qhov khoom tau txais nws cov khoom. Obviously, qhov zoo tagnrho yog kos cov khoom sib txawv hauv lawv cov txheej coj, ces koj yuav tsum saib xyuas tias koj cov txheej txheem tam sim no yog qhov uas cov khoom tsim yuav nyob. Los hloov cov txheej, peb tsuas xaiv nws los ntawm daim ntawv teev npe.
Yog tias peb xaiv ib qho khoom uas yog lwm tus txheej, qhov kev hloov pauv los qhia tias txheej, tab sis qhov ntawd tsis hloov qhov txheej txheem nyob rau hauv cov txheej txheem tam sim no, rau qhov ob khawm ntawm seem yog pab tau.

Koj tuaj yeem pom tias cov txheej txheem tseem ceeb tshaj plaws nyob rau hauv ob daim ntawv teev npe, hauv qhov chaw khiav dej num hauv tsev kawm ntawv thiab hauv cov khawm nyob hauv seem Ribbon. Qhov no yog qhov teeb meem ntawm cov lus txib uas yuav pab peb thaiv ib txheej, uas ua rau cov tsab ntawm nws muaj cov txheej txheem. Nyob rau hauv ib txheej thaiv peb muaj peev xwm tsim tau cov khoom tshiab, tiam sis tsis hloov cov khoom uas twb muaj lawm, uas yog ib qho zoo tshaj plaws kom tsis txhob hloov kev hloov.

Raws li peb tau piav thaum pib, peb tuaj yeem ua cov khoom ntawm ib txheej pom los yog ploj ntawm qhov kev tshuaj ntsuam txhais tau hais tias peb tau rho tawm los yog ntxiv cov acetates. Vim li no peb tuaj yeem lov tes taw los sis tsis tso nws. Cov nyhuv ntawm qhov screen yog thaj tib yam: cov khoom ntawm cov txheej txheej no tsis pom dua. Txawm li cas los, muaj dab tsi sib txawv hauv kev saib xyuas, cov khoom ntawm cov xiam khaubncaws sab nraud povtseg ua invisible, tab sis nws geometry yog tseem xam tau tias yog rau suav thaum ua Autocad regenerates lub screen tom qab ib tug Regen los yog Zoom hais kom ua, uas redraws txhua yam. Ntawm qhov tod tes, ua ib txheej tsis siv tsis tau tsuas yog ua rau cov khoom nws muaj tsis pom, tab sis nws tseem yuav tsum tsis pom zoo rau cov lus teb sab hauv. Nws zoo li yog tias cov khoom no tsis muaj nyob, txawm tias tsis muaj txheej txheem.
Qhov txawv ntawm ob qho tib si no tsis yog qhov tseem ceeb hauv kev kos duab yooj yim uas tau muab cov kev sib txuas ntawm cov lus teb sab hauv. Tiam sis thaum ib daim duab ua heev complex, disabling nws tej zaum yuav tswv yim yog hais tias peb dispense nrog ib co khaubncaws sab nraud povtseg rau ntev, vim hais tias peb txais kev cawm seej teb thiab yog li ntawd lwm lub sij hawm nqus ntawm lub screen. Tiam sis yog tias inutilizamos khaubncaws sab nraud povtseg nrog phav phav ntawm cov khoom yog mus yuav pom rau ib tug lub sij hawm ntawd thiab ces peb rov qab siv lub, peb yuam Autocad ua tag nrho cov suav tsuaj, uas yuav kav ib ob peb feeb. Nyob rau hauv cov mob nws yog qhov zoo dua rau deactivate.

22.3 txheej lim

Cov neeg ua hauj lwm hauv txhua qhov ntawm engineering los yog architecture, paub tias cov qauv siv ntawm cov haujlwm loj, xws li ib lub tsev loj lossis ib qhov chaw loj engineering, muaj kaum los yog pua pua pua cov txheej txheem. Qhov no txhais tau qhov teeb meem tshiab, raws li kev xaiv ntawm cov khaubncaws sab nraud povtseg, lawv txoj kev ua lossis kev ua kom tsis zoo los yog, qhov yooj yim, qhov hloov ntawm ib qho mus rau lwm tus txhais tau tias yog ib txoj haujlwm tseem ceeb ntawm cov pua lub npe.
Yuav zam tau qhov no, Autocad kuj tso cai rau koj rau kev ntxub ntxaug rau kev siv los ntawm kev tso npe lim. Lub tswv yim no zoo ib yam li cov duab lim uas peb pom hauv 16 tshooj. Li ntawd, peb tuaj yeem thov lub lim kom ua hauj lwm nrog cov pawg txheej uas muaj qee cov khoom los sis ib lub npe. Tsis tas li ntawd, nws tseem tuaj yeem tsim cov qauv uas cov txheej yuav tsum tau lim thiab txuag lawv rau yav tom ntej.
Cov ntxaij lim dej, tau kawg, yuav siv tau los ntawm Layer Properties Manager. Thaum koj nias lub khawm kom tsim tshiab cov ntxaij lim dej, cov dialog box qhov chaw uas koj muaj peev xwm nkag mus rau lub npe ntawm lub taub lim thiab xaiv ntawm khaubncaws sab nraud povtseg cov txheej txheem ntawm nyob rau hauv txhua zoo nkaus li. Hauv txhua kab, peb yuav tsum qhia meej txog cov yam ntxwv ntawm cov khaubncaws sab nraud povtseg kom pom. Ib qho piv txwv yooj yim yuav tsum xaiv cov txheej uas nws cov kab xim liab. Yog li, nws yuav suffice siv tej yam thaum lawv tseem cov khoom nyob rau hauv lub kab rau filtering khaubncaws sab nraud povtseg: kab hom, thickness, zajlus style, lub npe (siv wildcards) los ntawm lub xeev, yog hais tias lawv yog khov los yog muab xauv, thiab hais txog.

Qhov tseeb, qhov style ntawm lim cov khaubncaws sab nraud povtseg yog dab tsi, hauv databases, yog hu ua "query by example". Ntawd yog, nyob rau hauv kab peb muab cov txheej txheem uas peb xav tau, tsuas yog cov uas ua tau raws li qhov yuav tsum tau nthuav tawm.
Ntawm qhov tod tes, nws tseem tau lim cov khaubncaws sab nraud povtseg siv lawv cov npe, vim qhov no peb tsim cov kev lim kev siv cov cim tsiaj ntawv.
Piv txwv, xav tias peb muaj ib daim duab nrog cov txheej txheem hauv qab no:

1 Pem Teb Ntsa
2 Pem Teb Ntsa
3 Pem Teb Ntsa
4 Pem Teb Ntsa
1 Pem Teb Tu Hluav Taws Xob-a
1 Hluavtaws Hluav Taws Xob Hauv Tsev
2 Pem Teb Tu Hluav Taws Xob-a
2 Hluavtaws Hluav Taws Xob Hauv Tsev
3 Pem Teb Tu Hluav Taws Xob-a
3 Hluavtaws Hluav Taws Xob Hauv Tsev
4 Pem Teb Tu Hluav Taws Xob-a
4 Hluavtaws Hluav Taws Xob Hauv Tsev
1 Pem Teb Hydraulic thiab Kev Kho Mob Kom Huv
2 Pem Teb Hydraulic thiab Kev Kho Mob Kom Huv
3 Pem Teb Hydraulic thiab Kev Kho Mob Kom Huv
4 Pem Teb Hydraulic thiab Kev Kho Mob Kom Huv

Txhawm rau Autocad lim ob peb txheej, kom tsuas yog cov kev teeb tsa hluav taws xob tuaj yeem pom, peb tuaj yeem qhia cov cim cim nyob hauv ntu "Layer lub npe" los ntawm kev sau ntawv:

Pem Teb # Installation E *

Tej zaum muaj ntau yam zoo li paub lawv cov cim los tsim cov ntxaij lim dej rau hauv qhov tseeb yog tib yam li tau siv nyob rau hauv lub MS-DOS kev khiav hauj lwm qhov system commands xws li DIR nyob rau hauv ancient sij hawm, thaum Aragon tawm tsam Sauron yog li ntawd lub hobbit yuav ua kom puas lub nplhaib thiab cov computers tau tso rau qee qhov ntawm Gandalf tus khawv koob. Nws hais tias nyob rau hauv cov xyoo lub Microsoft software yog qhov chaw ua hauj lwm ntawm orcs.

Tab sis cia saib cov cim siv los tsim cov lim saum toj no. Lub cim # yog sib npaug rau ib tus neeg tus lej cim, yog li thaum siv cov lim dej, cov khaubncaws sab nraud povtseg uas muaj tus lej ntawm ib mus rau plaub tshwm nyob rau hauv txoj haujlwm ntawd; Lub hnub qub hloov pauv rau txhua txoj hlua ntawm cov cim, yog li muab nws tom qab "E" tshem tawm tag nrho lwm cov khaubncaws sab nraud povtseg uas tsis muaj "Electric" hauv lawv lub npe. Cov lim no kuj yuav tau ua haujlwm raws li hauv qab no:

Pem Teb # Hluav taws xob Installation- *

Lub cim hnub qub thiab cov kos npe # tsis yog cov cim uas siv los tsim cov txheej lim. Cov npe nram no nthuav txog qee yam siv:

@ (ntawm) Nyob rau hauv koj txoj hauj lwm muaj peev xwm ua tau cov cim ua yeeb yam. Hauv peb
Piv txwv li, 2 Hluavtaws Hluav Taws Xob-lub npog ntsej muag yuav qhia li cas
2 ua cov khaubncaws sab nraud povtseg.

. (lub sij hawm) Sib npaug rau ib qho tsis-alphanumeric tus cwj pwm, xws li hyphens,
ampersand, quotes los yog tej qhov chaw.

? (kev nug lus) tuaj yeem sawv cev txhua tus neeg. Piv txwv,
nws yuav zoo li qub kom tso Pem Teb # M * tias, Pem Teb? M *

~ (Tilde) Tsim ib qho kev lim tawm tshwj xeeb yog tias nws siv thaum pib ntawm lub npog ncauj.
Piv txwv, yog peb muab tso ~ Pem teb # Inst * yuav cais tawm ntawm qhov kev xaiv
rau tag nrho cov txheej ntawm hydraulic thiab sanitary sib.

Txawm li cas los xij, nws tseem tuaj yeem tsim cov pab pawg ntawm txheej tsis tas muaj qhov sib txawv, xws li kab los yog xim yam ntxwv lossis qee lub cim ntawm lawv lub npe thiab, yog li ntawd, yuav tsum tau hais txog cov ntaub ntawv kaw tseg.
Pawg Cov Filters yog cov txheej ntawm cov txheej uas tus neeg siv tau xaiv ntawm yuav. Los tsim ib qho, peb nias qhov sib thooj khawm, peb muab nws lub npe thiab, yooj yim, peb ntes cov txheej uas peb xav ua ib feem ntawm pawg ntawd los ntawm cov npe ntawm sab xis. Nyob rau hauv no txoj kev, thaum nias ntawm lub lim tshiab, cov khaubncaws sab nraud povtseg uas peb tau ua tiav rau nws yuav tshwm sim.

Xav txog tias kev tsim cov ntxaij lim dej thiab cov neeg lim dej tsis muaj kev cuam tshuam rau cov khaubncaws sab nraud povtseg ntawm lawv tus kheej thiab, tsawg dua, ntawm cov khoom uas lawv muaj. Yog li koj tuaj yeem tsim tau ntau ceg ntoo raws li koj xav tau nyob rau hauv koj qhov ntoo pom nrog lub tswv yim ntawm ib txwm muaj ib daim ntawv teev cov txheej txheem ntev. Nyob rau hauv no txoj kev nws yuav hardly poob tswj dua.
