Ukuzabalazela phambi kweendlela eziqhelekileyo zoshishino, sizama ukuvelisa umgangatho ophezulu wegranite ochanekileyo wesikwere esingunxantathu.Usebenzisa eyona granite emnyama yeJinan egqwesileyo njengemathiriyeli ekrwada, isikwere esichanekileyo segranite esingunxantathu sisetyenziswa ngokufanelekileyo ukujonga ulungelelwaniso oluthathu (okt X, Y kunye no-Z umgca ohamba phambili) wedatha ebonakalayo yezinto ezimatshini.Umsebenzi weGranite Tri Square Ruler uyafana neGranite Square Ruler.Ingakwazi ukuncedisa isixhobo somatshini kunye nomsebenzisi wokwenza oomatshini ukwenza uhlolo lwe-angle echanekileyo kunye nokubhala kwiingxenye / izinto zokusebenza kunye nokulinganisa i-perpendicular yamacandelo.
