Amabhuloho wokuhlanza amathangi aphezulu enziwa yithi asetshenziswa kakhulu emkhakheni wokuhlanza udonga lwangaphakathi, ipayipi lokuhlanza udonga lwangaphakathi neminye imikhakha. Phakathi kwabo, ukuhlanzwa kodonga lwangaphakathi lwesitsha kuyinkimbinkimbi kakhulu. Ngenxa yomehluko wobubanzi bodonga lwangaphakathi lwesitsha esidinga ukuhlanzwa, siklame futhi sathuthukisa ngokuya ngobubanzi obuhlukile. Uchungechunge lwemibhobho yokuhlanza amathangi ingahlangabezana nezidingo eziningi zohlelo lokusebenza.

Imibhobho yokuhlanza amathangi ihlukaniswe izindlela ezintathu zokuhlanza. Owokuqala ngumbhobho wokuhlanza ohleliwe. Umbhobho awunazo izingxenye ezihambayo emzimbeni wonke. Konke kulungisiwe. Umzimba wonke wombhobho ugcwele umbhobho wesigaxa ogcwele, ongafafaza esikweleni ngasinye. Ukuze uhlangabezane nezidingo zokuhlanzwa okuphelele kodonga lwangaphakathi lwesitsha.

Uhlobo lwesibili imbhobho yokuhlanza ejikeleza i-axis eyodwa. Ikhanda lalo lokufafaza lingazungeza kuphela othini lokuphotha lwentambo lombhobho, ngakho-ke ukuqondiswa kwalo kwesifutho ngokuvamile kuyisimo somphathi oyisicaba, ngoba kungakumboza ngokuphelele yonke ingaphakathi lesitsha.

Uhlobo lwesithathu ngumbhobho ojikelezayo we-3D, ongazungezi kuphela uzungeze umbhobho wentambo yokuphotha, kodwa futhi uzungeze i-eksisi yombhobho ojikelezayo, ukuze kuthi noma ufafaza iphuzu kuphela, ungahlanzwa ngokuphelele ngemuva kwesikhathi esithile ukuzungezisa. Odongeni lwangaphakathi lomgqomo, amandla okuthinta lo mbhobho mkhulu kakhulu, ngakho-ke kufanelekile ukuhlanza udonga lwangaphakathi lweziqukathi ezinobubanzi obukhulu.
