Contours kusukela polylines (Isinyathelo 1)
Ngaphambi kokuba sibone ukuthi kanjani dala ama-contours ukuqala kunethiwekhi yamaphoyinti athathwe ensimini. Manje sizobona ukuthi singakwenza kanjani, kusuka kumajika akhona kumephu eskeniwe.
Njengoba senza ne ukuklama komgwaqo, asiphule sibe yizinyathelo, ukuze okuthunyelwe kungapheli isikhathi eside kunalokho inyoka yezinyoka.
Faka isithombe
Ngalokhu, uma unezixhumanisi eziseceleni ku-UTM, umsebenzi wenziwa lula kakhulu. Kulokhu, imiphambanandlela yezixhumanisi eziseduze nemikhawulo iyabonakala, ukube ukuhlangana kwamakhona bekungaba kuhle kakhulu.

Amaphuzu afakwe ngomyalo iphuzu, nokufaka ukuxhumanisa okuhlukaniswe ngukhefana, njengoba kukhonjisiwe esithombeni esingezansi. Ukushintsha ifomethi yamaphoyinti ibe wuphawu olubonakalayo, kwenziwa kusuka ku- Ifomethi> isitayela sephoyinti. Kepha njengoba lezi zinguqulo ze-Civil 3D zikwenza kube nzima ukuthola imenyu Amathuluzi, ungabhalela endala: i-ddptype kusuka emgqeni wokulalela, ke faka futhi sikhetha uhlobo lwephoyinti.
Kule ngxenye engaqondakali i-Microstation, lapho iphuzu liwubude besikhathi sobude, futhi lungaba nobukhulu obunamandla ngokubuka kwemephu.
Manje sifaka isithombe, sisebenzisa Faka> Ukubhalwa kabusha kwesithombe se-Raster. Sikushiya unike amandla amathuba okubeka i- Iphoyinti lokufaka y isikali kusuka kusikrini.
Bese ubeke iphuzu ngakwesokunxele kwezixhumanisi bese uhambisa igundane uze ubone ukuthi isithombe sisayizi esilinganiselwe.
Uma isithombe sihlanganisa amachashazi, sithumele futhi. Lokhu kwenziwa nge Amathuluzi> Khombisa ukuhleleka> Thumela emuva.
I-Georeferencing isithombe.
Sizodinga amaphuzu esithombeni alingana nalezo esizifakile sisebenzisa izixhumanisi. Ngalokho, sijoyina imigqa eseceleni, ukuze sithole iziphambano.
Ukusebenzisa umyalo Imephu> Amathuluzi> Ishidi Lenjoloba, njengoba sasisebenzisa izinsuku ezimbalwa ezedlule guqula ama-vectors, sibonisa iphuzu eliluhlaza njengesisekelo, bese kuthi elibomvu njengesethenjwa. Lapho sesikwenze ngakho konke okune, siyakwenza faka futhi umyalo usicela ukuthi sikhethe izinto ezizoguqulwa. Sibhala izingoma S, ngokukhetha Khetha, futhi sithinta isithombe, bese sikwenza faka isikhathi sokugcina naso sinawo.
Okufanayo okufana nalokho i Warp i-del Umphathi we-Raster ku Microstation. Njengoba siyichaza ukuthi kufanele nini imidwebo ye-georeferencing kusuka ku-Google Earth.
Bona ukuthi manje isithombe sifana kanjani namachashazi abomvu, lawo aluhlaza angaqedwa. Manje isithombe sesibonisiwe futhi esikalini esifanele ukuqala ukwenza i-digitization. Kulesi sixhumanisi kunjalo Ungabona isinyathelo se-2 ukuqedela lo msebenzi.
Eshu, angizange ngibone ukuthi sasingekho isixhumanisi sesinyathelo esilandelayo. Ekupheleni kokuthunyelwe ngikhombisile ukuthi ungayibona kanjani i-athikili lapho kushiwo khona ukupheleliswa komsebenzi.
A ukubingelela.
Okuthakazelisayo kakhulu, le miyalo isebenzisa nsuku zonke. Izinyathelo ezilandelayo zokwenza ama-curves kusuka kuskena, ngibathola kanjani?
Gracias
Sawubona, lesi sihloko siyathandeka kakhulu. Ngingawulanda kanjani lolu lwazi oluwusizo?
I-gracias
Kunjalo, ivele ijikelezise, ikale futhi inyakaze. Akukho ukuhlanekezela ngale kwalokho, ngokubona kwami.
Sawubona sawubona… Lesi sihloko siyathakazelisa, uma sikhuluma iqiniso angikaze ngisebenzise lowo myalo othi “Ishidi Lerabha”.
Lapho wenza i-georeferencing nalo myalo, uma iphikisana nesithombe? o Ukulinganisa isithombe kuphela.
Futhi ngokusho komqulu we-autocad, kungenzeka kuphela ngamaphoyinti aphezulu we-4 (uma kwenzeka endaweni) kuyiqiniso? Kwenzekani uma isithombe siphenduka sibheke maphakathi nesithombe?
