Daim Duab 3D nrog AutoCAD - Tshooj 8

TSHOOJ 37: KHOOM NO

Thaum cov 3D cov khib nyiab tau muab txhais hauv 36.2.1, peb pom tsis tau ntxiv cov kev sib txawv uas peb tau tsim thiab hloov kho thoob plaws hauv tshooj lus no.

37.1 Khoom los ntawm cov khoom yooj yim

37.1.1 Extrusion

Thawj txoj kev los tsim cov khoom ntawm 2D profile yog extrusion. Nws yuav tsum yog qhov profile kaw lossis lwm tus yuav tshwm sim, tsis yog ib qho khoom. Thaum twg tus profile yuav tsum extruded xaiv, peb muaj peev xwm tsuas yog qhia ib qhov siab qhov nqi los yog xaiv ib yam khoom uas ua hauj lwm raws li ib tug trajectory. Txawm li cas los, lub inclination thiab cov duab ntawm cov khoom ntawd yuav tsis txhais tias cov khoom ua tau overlaps nws tus kheej thiab yog tias muaj, Autocad yuav kos tus cim yuam kev thiab yuav tsis tsim cov khoom. Yog li, qee zaum, nws zoo dua yog siv cov txheej txheem cheb uas yuav tau los tham tom qab. Ntawm qhov tod tes, yog tias peb qhia ib lub kauj inclination ntawm koj cov kev xaiv, cov tawv yuav hwv. Thaum kawg, qhov Chaw Nyob Txuj Nkag tso cai rau, los ntawm kev xaiv 2 cov ntsiab lus, los qhia txog qhov kev taw qhia thiab ntev ntawm extrusion, uas yog, nws yog lwm txoj hauv kev los mus qhia ib tus trajectory.

37.1.2 Cheb

Nrog rau kev hais kom ua sweep peb tuaj yeem tsim ib qho khoom los ntawm ib qho kaw 2D nkhaus, uas yuav los ua ib qhov profile, cheb nws raws lwm 2D khoom uas ua hauj lwm raws li ib tug trajectory. Ntawm nws cov kev xaiv peb tuaj yeem tig cov khoom thaum lub sij hawm sweep, los yog hloov nws qhov kev ntsuas.

37.1.3 Lightening

Lub Loft hais kom ua ib qho khoom los ntawm kev kaw 2D nkhaus profiles uas ua hauj lwm raws li kab lus. Autocad tsim cov khoom hauv qhov chaw nruab nrab ntawm cov tshooj no. Nws tseem tau siv ib co kev nplua los yog polyline ua ib txoj kab sab nraud. Yog tias daim ntawv kawg ntawm cov khoom tsis txaus siab rau koj, koj tuaj yeem siv cov kev xaiv ntxiv uas muaj lub thawv tawm tswv yim uas muaj tshwm sim nrog cov kev xaiv kawg.

37.1.4 Revolution

Revolution Solids kuj xav kom kaw 2D profiles thiab ib qho khoom uas ua hauj lwm raws li lub axis ntawm kiv puag ncig los yog cov ntsiab lus uas txhais tau hais tias cov axis. Yog hais tias lub nruas axis tsis yog ib txoj kab, ces tsuas yog nws pib thiab qhov kawg taw tes yuav muab suav hais tias yog txhais lub axis. Losyog, lub lemkem pheej hloov yog 360 degrees, tabsis peb tuaj yeem qha tau lwm yaam ntxiv.
