Daim Duab 3D nrog AutoCAD - Tshooj 8

36.1.2 References rau 3D khoom

Hauv tshooj 9 peb tham txog qhov zoo ntawm Cov Lus Qhia rau cov khoom thiab thoob plaws cov ntawv peb tau hais ntau nyob rau hauv. Ntawm no, qhov yooj yim, peb yuav tsum taw qhia tias peb tuaj yeem ua tiav cov kev xa mus ntawm 3D cov khoom, uas yuav muab ntxiv rau yav dhau los. Txhawm rau ua kom lawv, peb siv lub pob ntawm lub xwm txheej bar. Nws cov ntawv qhia zaub mov ntsiab lus yuav cia peb teeb tsa lawv kom paub meej.

36.2 Yam Hom

Raws li peb yuav pom tom qab, ntau hom 3D cov khoom sib hloov nrog txhua lwm yam. Los ntawm cov khoom peb tuaj yeem tsim cov khoom saum npoo, los ntawm no ib qho khoom siv mesh thiab los ntawm cov khoom siv mesh cov khoom tawm. Hauv txhua qhov ua tau ua ke thiab hwm cov cai hloov ua lwm yam, tau kawg. Thaum ib yam khoom 3D yog ib hom tshwj xeeb, nws muaj hauv cov txheej txheem kho cov cuab yeej uas nws tsis muaj thaum nws yog ntawm lwm hom. Piv txwv li, qhov ntim ntawm cov khoom kwv yees tuaj yeem muab rho tawm los ntawm lwm qhov loj dua, los ntawm kev ua haujlwm sib txawv, tawm qhov sib txawv hauv nws. Ib zaug yog li ntawd, nws tuaj yeem hloov mus rau thaj chaw saum npoo los kho qee cov ntsiab lus los ntawm kev tswj hwm cov kab ke thiab tom qab ntawd lub mesh ib qho los ua kom zoo rau kev sib luag ntawm lawv cov ntsej muag, ntawm cov neeg muaj peev xwm ntau.

Cia peb txhais cov hom 3D cov khoom uas peb tuaj yeem tsim nrog Autocad.

36.2.1 Solids

Cov khib nyiab yog cov khoom kaw uas muaj lub cev: lub cev, qhov ntim, qhov nruab nrab ntawm lub ntiajteb txawj nqus thiab lub sijhawm ntawm inertia, nrog rau lwm cov ntsiab lus qhia tawm los ntawm Propfis cov lus txib (uas muaj cov cim txwv yuam kev thaum qhov khoom tsis tau tsim).
Cov khib nyiab tuaj yeem tsim los ntawm cov qauv yooj yim (hu ua thawj zaug) thiab tom qab ntawd ua ke, lossis tsim los ntawm cov ntaub ntawv 2D kaw. Nws kuj tseem tuaj yeem ua Boolean kev khiav haujlwm nrog lawv, xws li koom ua ke, kev sib tshuam thiab sib txawv.

36.2.2 Plaub Hlis

Qhov saum npoo yog "hollow" 3D khoom uas yog li tsis muaj huab hwm coj, ntim, lossis lwm yam khoom siv lub cev. Lawv feem ntau tau ua kom tau txais txiaj ntsig ntawm ntau yam kev sib koom ua qauv thiab cov cuab yeej sculpting. Muaj ob hom ntawm qhov chaw: txheej txheem thiab NURBS nto, uas, raws li peb yuav pom, muaj feem xyuam rau splines, vim lawv kuj tuaj yeem hloov kho nrog kev tswj vertices.

36.2.3 Tights

Mesh khoom paub zoo tias yog cov uas tau tsim ntawm lub ntsej muag (lub voos plaub lossis duab plaub fab) uas hloov ntawm cov kaum qaum thiab npoo. Lawv tsis muaj qhov loj lossis lwm yam khoom siv ntawm lub cev, txawm hais tias lawv faib qee cov cuab yeej ua nrog cov khib nyiab thiab qee qhov nrog thaj chaw. Lawv lub ntsej muag tuaj yeem raug cais mus rau ntau lub ntsej muag kom muag tau yam khoom, nrog rau lwm cov kev hloov kho.

36.3 3D khoom ua haujlwm

Raws li peb tau hais, txhua yam khoom ntawm 3D tus kheej muaj nws cov cuab yeej kho kom raug. Txawm li cas los xij, lawv txhua tus faib qee cov lus txib uas, dua li ntawm kev kho lawv tus kheej, cia peb tswj hwm lawv yam tsis muaj qhov txwv ntawm 2D cov cuab yeej uas peb tau pom hauv ntu 36.1.1. Peb mus saib

36.3.1 Gizmos 3D

Hauv seem Hloov ntawm nplooj ntawv Lub Tsev ntawm 3D Lub Chaw Haujlwm peb muaj cov cuab yeej 3 hu ua Gizmos 3D: Tsiv Mus, Kev Sib Hloov thiab Nplai. Qhov tseeb, thaum peb xaiv ib qho 3D kwv, los ntawm lub neej ntawd ib ntawm cov gizmos tshwm nyob rau hauv nruab nrab ntawm cov khoom, uas tau teeb tsa hauv ntu Xaiv (thiab ntev li ntev los, ntxiv rau, hom kev pom tsis yog 2D tus qauv). Txawm hais tias peb tseem tuaj yeem xaiv cov gizmo uas xav tau nyob hauv txoj kev pob tw, tau kawg.
3D Offset gizmo tso cai rau koj rhais lub npov lossis cov khoom raug xaiv los ntawm kev yooj yim qhia qhov axis lossis dav hlau (XY, XZ lossis YZ) los ntawm kev peb xav tsiv lub zog. Txhawm rau ua qhov no, ntxiv rau lub cim SCP ntawm lub hauv paus taw tes ntawm kev tshem tawm. Qhov no thiab lwm yam gizmos kuj tseem siv tau nrog 2D khoom.

Kev sib hloov 3D, raws li lub npe cuam tshuam, tso cai rau koj kom tig cov khoom lossis cov khoom raug xaiv siv cov txheej txheem zoo ib yam, uas yog, kab kos axis ntawm gizmo nws tus kheej. Tom qab ntawd peb tuaj yeem qhia lub kaum sab xis ntawm lub qhov rai kab hais kom ua, lossis siv tus nas. Nyob rau hauv txhua rooj plaub, txoj kev sib hloov tau txwv rau txoj kab uas raug xaiv.

Thaum kawg, 3D Nplai resizes qhov khoom lossis khoom siv kom tag nrho (yog li tsis tuaj yeem txwv nws. Qhov ntsuas ntsuas yuav raug ntes nyob rau ntawm lub kab ntawv hais kom ua kab, lossis qhia sib cuam tshuam nrog tus nas, tej zaum siv cov khoom xa mus rau nqa cov khoom mus rau qhov loj me me.
Peb yuav tsum ntxiv hais tias cov ntawv qhia zaub mov hauv keeb kwm ntawm gizmos tso cai rau peb hloov ntawm ib qho mus rau lwm lub gizmo thiab, yog tias Hloov thiab Kev Sib Hloov, xaiv qhov axis lossis dav hlau uas peb xav txwv txoj haujlwm, ntawm lwm yam kev tuaj yeem.
