Hloov Cov Khoom Siv nrog AutoCAD - Tshooj 4

TSHOOJ 18: TXHEEJ TXHEEM

Tshaj li cov txheej txheem editing uas yuav ua tau rau txhua txoj haujlwm, xws li luam lossis rho tawm, Autocad muaj ib txheej ntxiv ntawm cov lus txib los hloov cov khoom uas yog kev teeb tsa kev kos duab. Raws li koj tuaj yeem pom hauv qab no, ntau cov kev hloov kho tshwj xeeb no tsim cov khoom tshiab thiab hom CAD daim duab.

18.1 Offset

Cov lus hais tawm Offset tsim cov khoom tshiab ntawm qhov kev ncua deb ntawm cov khoom uas twb muaj lawm. Nws tsis yog ib txwm hais txog ntau yam ntawm lawv. Piv txwv, nyob rau hauv cov ntaub ntawv ntawm lub voj voog, Cov neeg ua haujlwm tsim cov voj voog tshiab uas muaj, vim li no, ib lub vojvoog txawv ntawm lub vajvoog qub, tab sis tib qhov chaw. Nyob rau hauv cov ntaub ntawv ntawm cov hlab ntsha, tus duplicate tuaj yeem muaj tib lub chaw thiab tib lub zeem muag, tab sis ntau dua los sis tsawg dua arc ntev nyob ntawm sab ntawm thawj qhov uas nws muab tso rau. Hauv kev sib piv, thaum peb siv qhov hais kom ua nrog ib tus kab kab, peb tau txais ib kab tshiab raws nraim tib yam li thawj kab, tab sis nyob ntawm qhov kev qhia tau hais tias qhov chaw nyob.
Thaum ua tiav qhov kev hais kom ua, Autocad nug peb rau qhov kev ncua deb uas qhov khoom tshiab yuav los yog qhov taw qhia ntawm qhov point uas nws yuav tsum hla. Tom qab ntawd thov kom cov khoom yuav tsum tau duplicated thiab, thaum kawg, lub sab nyob rau hauv uas nws yuav tsum tau muab tso rau. Txawm li cas los xij, qhov kev hais kom tsis txhob xaus rau ntawm no, Autocad rov thov dua tshiab cov khoom, nrog lub tswv yim tias peb muaj peev xwm tsim ntau yam duplicates ntawm tib qhov chaw nyob deb.
Ib daim ntawv thov uas piav txog qhov kev hais kom ua no yog kos duab ntawm phab ntsa hauv tsev.

18.2 Symmetry

Symmetry tsim, raws li lub npe implies, cov khoom cim rau lub hauv paus ntawm ib txoj kab xo. Colloquially, peb tuaj yeem hais tias nws duplicates xaiv cov khoom tab sis txhais tau hais tias lawv muaj kev cuam tshuam hauv ib daim iav. Qhov saum npoo ntawm daim iav, pom perpendicularly, yuav yog qhov axis ntawm symmetry.
Thaum peb qhib qhov kev hais kom ua thiab xaiv peb cov khoom, Autocad nug 2 cov ntsiab lus tsim lub axis ntawm symmetry thaum peb kos ib kab. Yam khoom siv tshiab uas nyob ntawm qhov ze thiab lub kaum sab xis ntawm txoj kab ntawm symmetry uas yog yam khoom qub. Tom qab txhais lub axis, peb tuaj yeem xaiv los rho tawm qhov qub lossis khaws nws.
