Summada tolsan waa summada ugu caansan ee dharka, Theku calaamadeewaxaa lagu tolaa tolka iyadoo lagu hagaajinayo duntaduntaiyo isticmaalka haraggaduntasi ay u muujiyaancalaamad,erayada, xarfaha, garaafyada, tirooyinka, calaamadaha saddex-geesoodka ah.

Marka loo eego sifooyinka alaabta, waxaa loo qaybin karaa laba qaybood: heerka diyaaradda iyo heerka satin.

Halbeegga diyaaradda: Maro sida qaab-dhismeedka maro, fudud mar dunta dhex-xidhay heerka diyaaradda fudud.Guud ahaan, dagaalku wuu go'an yahay, ama madow, ama caddaan, markaa waxaa jira madow iyo caddaan iyo fidsan, calaamad midab asal ah, guud ahaan leh dabaq cad, madow badanaa leh dabaq madow.Habka iyo midabka calaamadda marada waxaa inta badan lagu muujiyaa dunta dunta, iyo midabka la muujiyay wuu ka duwanaan doonaa sababtoo ah saameynta ka gudubka dunta fidsan.Sababtoo ah mashiinku wuxuu leeyahay xaddidaadda noocyada dunta dunta, sidaas darteed midabka waxaa lagu muujin karaa xaddidan, guud ahaan 8 nooc.Sida kor laga arki karo, qaybaha qiimuhu waa: ballaca marada, taas oo ah, qadarka qulqulka loo isticmaalo;Dhererka marada, iyo dhererka midab kasta oo weheliya meeriska.Si aad u muujiso tafaasiil badan iyo midab, labanlaab dhammaan weftyada, oo loo yaqaan laba-dhinac, haddii midabku u baahan yahay saddex-geesood oo dheeraad ah, ku dar miisaanka dunta, oo loo yaqaan shuttle culus.Dhaqidda iyo cabbiridda ka sokow, inta badan isticmaalka calaamado siman oo laba-dhinac ah.Calaamadaha dharka ayaa ah dun si ay u muujiyaan qaabka, waana in ay jiraan kala duwanaansho naqshadeynta garaafka asalka ah, sidaas darteed suurtagal maaha in la sameeyo wax soo saar ballaaran iyada oo aan la xaqiijin muunad.
