I-grid yokuhlela i-UTM usebenzisa i-CivilCAD

Ngisanda kukutshela I-CivilCAD, uhlelo olusebenza ku-AutoCAD nakuBricscad; ngalesi sikhathi ngifuna ukukhombisa indlela yokwenza itafula lokuxhumanisa, nje njengoba sibonile ukuthi kwenziwa nge-Microstation Geographics (Manje iMephu yeBentley). Imvamisa lezi zinto Izinhlelo ze-GIS zinakho eliwusizo kakhulu, kodwa ngaleso CAD ezingeni namanje ikani, nakuba kufanele elakhiwe Vector indlela, ukulahlekelwa ashukumisayo futhi ezidinga ezinye ethehlsasi kwemaphutsa.

Kunezinketho ezimbili ku-CivilCAD: UTM Coordinates neGeographic.

I-1 I-Georeferencing ifayela le-CAD.

Njengoba sinakho kuchazwe ngaphambili, iqiniso lokuthi ukulinganisa kungaphakathi UTM iqondisa akusho ukuthi kuyisimo se-georeferenced, ngoba izixhumanisi ezifanayo ziphindaphindiwe kwezinye izindawo, ngakho-ke kufanele uchaze ukuthi iyiphi indawo osebenza kuyo.

Lokhu kwenziwa nge: I-CivilCAD> Shintsha okuguqukayo.

Ngendlela efanayo, ukuze sikwazi ukukhiqiza izixhumanisi zendawo, kufanele sichaze izakhiwo ze-ellipsoid, uma zihlukile kulowo i-GRS80 / WGS84 isivele isilungiselele:

• Indawo ye-UTM
• Ubude obukhulu
• Ububanzi be-Zone (degrees), ngokuvamile i-6
• Le manga, ngokuvamile i-500,000
• I-coefficient engenalutho eqondile
• Isici sezinga eliphakathi
• I-longitude ye-meridian ephakathi, lena yi-méridian ephakathi nendawo
• Amanga enyakatho.

I-2 Igalari yokuxhumanisa ye-UTM

Kulokhu, kukhethwe kwimenyu ye-CivilCAD, i-reticle bese i-UTM; noma umyalo ngesandla -RETUTM, ke faka.

Kulayini wokuyala, umyalezo wokukhetha ibhokisi lesithakazelo sethu uyavela, bese kukhethwa amakhona amabili endawo ezofakwa ilebula. Kungakuhle ukuthi i-snap isebenze, ukuze imigqa iqondane ncamashi nonqenqema, i snap ivuliwe noma ivinjelwe ngomsebenzi wekhibhodi we-F3.

Ngemuva kwalokho umyalezo uvela wokuthi igridi iyasithanda kangakanani; kulokhu ngizokhetha abangama-200. Futhi lapho sinayo, elula, ngaphandle kwenkinga enkulu kodwa enezinketho ezimbalwa njengoba kwenza iMicrostation.

Ukuze ushintshe umbala wetheksthi noma we-crossheads, kuyenziwe ukuguqula kuwo izingqimba kwenziwa kule nqubo; I-CVL_RETU TM ne-CVL_RET_TX. Ukuze ungangcolisi i- imodeli, lokhu kufanele kwenziwe ku- layout.

I-3 I-reticle yezixhumanisi zezwe

Ngenxa yalokhu, sikhetha ukhetho lwesibili, noma umyalo -RETGPS futhi siphendula kulokho okusibuzayo (Ibanga phakathi kokulinganisa ngemizuzwana)

Ukuze ushintshe usayizi wombhalo, kwenziwa nge:  I-CivilCAD> Umbhalo> Chaza Ukuphakama Kwombhalo.

I-cosillas elula, lokho I-Civil3D Kufanele ngikwenze ngaphandle kokubuya okuningi.
