UTM idibanisa igridi usebenzisa i-CivilCAD

Kutshanje wathetha nabo malunga KwiCACC, isicelo esisebenza kwi-AutoCAD kunye ne-Bricscad; ngeli xesha ndifuna ukukubonisa indlela yokuvelisa itafile yokulungelelanisa, nje njengoko sibonile ukuba kwenziwa nge-Microstation Geographics (Ngoku iMephu yeBentley). Ngokwesiqhelo ezi zinto Iiprogram ze-GIS zinalo ngezinga eliphezulu, kodwa kwinqanaba le-CAD liyakwazi, kuba nangona zivelisiwe kufuneka zenziwe ngendlela engavumelekanga, ilahlekelwe yintsholongwane kwaye idinga ukuhlelwa kohlelo lokuhlela.

Zimbini iindlela onokukhetha kuzo kwi-CivilCAD: ii-UTM Coordinates kunye neJografi.

1 I-Georeferencing ifayili ye-CAD.

Njengoko sinakho kuchaziwe ngaphambili, into yokuba umlinganiselo ungaphakathi UTM izilungiso akuthethi ukuba i-georeferenced, kuba ulungelelaniso olufanayo luphindaphindiwe kwezinye iindawo, ukwenzela ukuba kufuneka uchaze kwindawo osebenza kuyo.

Oku kwenziwa nge: CivilCAD> Guqula izinto eziguquguqukayo.

Ngendlela efanayo, ukuze sikwazi ukuvelisa ukulungelelaniswa kweendawo, kufuneka sichaze iipropati ze-ellipsoid, ukuba ngaba zihluke kwi-GRS80 / WGS84 sele isilungiselelwe:

• Indawo ye-UTM
• Ubude obude
• Ububanzi bebala (amazinga), ngokuqhelekileyo i-6
• Lo buxoki, ngokuqhelekileyo i-500,000
• I-coefficient engaphantsi
• Umgangatho wezinga eliphakathi
• Umda we-meridian ephakathi, lo yi-meridiya ephakathi kwendawo
• Amanga angasentla.

2 Grid Coordinate Grid

Ngenxa yoko, kukhethwe kwimenyu ye-CivilCAD, i-reticle uze u-UTM; okanye umyalelo ngesandla -RETUTM, ngoko ukungena.

Kumgca wokuyalela, umyalezo oza kukhetha ibhokisi yomdla wethu uyavela, emva koko kukhethwe iigumbi ezimbini zelebhile. Kuyacetyiswa ukuba i-snap isebenze, ukuze imigca ihambelane ngqo nomda, i i-snap isebenze okanye ivalwe ngokusebenza kwekhibhodi yeF3.

Emva koko umyalezo ubonakala ukuba igridi inomdla kangakanani kuthi; Kule meko ndiza kukhetha i-200. Kwaye apho sinayo, elula, ngaphandle kwengxaki enkulu kodwa ngeendlela ezimbalwa njengoko iMicrostation isenza.

Ukutshintsha umbala wesicatshulwa okanye i-crossheads, yenziwe yatshintsha kuyo iziqendu kuveliswe kule nkqubo; I-CVL_RETU TM kunye neCVL_RET_TX. Ukuze ungangcolisi i- imodeli, oku kufuneka kwenziwe kwi Kuluhlu.

3 Iingqungquthela zeendawo zokudibanisa

Kule nto, sikhetha ukhetho lwesibini, okanye umyalelo -RETGPS kwaye siphendula kwinto esiyicelayo (Umgama phakathi kwemilinganiselo ngemizuzwana)

Ukutshintsha ubungakanani bombhalo, kwenziwa nge:  CivilCAD> Umbhalo> Chaza ubude beetekisi.

I-cosillas elula, oko Civil3D Ndimele ndenze ngaphandle kokubuya okukhulu.
