Ngā tīwiri Sems, ngā tīwiri whakakotahi pane paraharaha,

Ko te tīwiri whakakotahi e pā ana ki te huinga o te tīwiri me te horoi puna me te horoi papatahi, e herea ana mā te mirimiri i ngā niho. Ko ngā huinga e rua e pā ana ki te tīwiri me te horoi puna kotahi anake, ki te horoi papatahi rānei. Ka taea hoki te rua ngā huinga me te niho putiputi kotahi anake.

Ko te rauemi o te tīwiri whakakotahi kua wehea ki te kowiri tira me te rino, ko te rino ia he mea hanga ki ngā waea porowhita rino rerekē. Ko te waea e whakamahia ana mō ngā tīwiri whakakotahi whānui ko te 10101018, 10B21, me ētahi atu. Ka whakamahia te 10B21 hei hanga tīwiri whakakotahi taumata 8.8, pērā i ngā tīwiri whakakotahi hexagonal taumata 8.8. Ko ngā tīwiri whakakotahi kowiri tira e whakamahia whānuitia ana me ngā tīwiri whakakotahi SUS304201, he onge te whakamahinga nā te mea he uaua ki te whakahaere i te pakeke o te waea tīwiri kowiri tira 201, ā, he ngāwari ki te pakaru. 

Ko te whakakikoruatanga hiko o ngā tīwiri whakakotahi e pā ana ki te whakakikoruatanga hiko o ngā tīwiri whakakotahi rino. Ka taea te wehewehe i te whakakikoruatanga hiko ki ngā tae pai mō te taiao me ngā tae kore pai mō te taiao. Ko ngā tae whakakikoruatanga hiko e whakamahia whānuitia ana mō ngā tīwiri whakakotahi ko te tae pai mō te taiao ko te konutea, te konutea kikorangi pai mō te taiao, te konutea mā pai mō te taiao, te nikara pai mō te taiao, te tae whero, te konutea mā, te nikara mā, me ētahi atu. Ko te kaupapa o ngā tīwiri whakakotahi whakawhiti-kōpuku, ngā pūtu whakakotahi hexagonal, me ngā tīwiri whakakotahi ā-ringa he rite tonu ki ngā tīwiri whakawhiti-kōpuku, ngā pūtu pane hexagonal, me ngā tīwiri ā-ringa. Ko te āhuatanga matua o ēnei tīwiri whakakotahi ko te mea he rite tonu ngā horoi katoa, he tino watea ki te whakamahi. 

I te nuinga o te wā, he whānuitia te whakamahinga o ngā tīwiri whakakotahi i roto i ngā taputapu hiko, hiko, mīhini, hikohiko, taputapu whare, taonga whare, kaipuke, me ērā atu mea. Engari he rerekē ngā mahi a ngā tīwiri whakakotahi rerekē, pērā i ngā tīwiri whakakotahi pane whakawhiti, e whakamahia whānuitia ana ki ngā hua hiko iti. Ko ngā tīwiri whakakotahi tapawhā whakawhiti nui ake e whakamahia ana ki ngā hua hiko nui ake, pērā i ngā kaitahuri auau. He maha ngā tīwiri whakakotahi tapawhā whakawhiti e wātea ana i ētahi kaitahuri auau nui ake. Pāwhiria te anga o te kaitahuri auau hei wetewete me te whakau.

Ā, ko ngā tīwiri huinga e rua me ngā niho putiputi ka whakamahia ki te kaitahuri auau hei wawahi i te peita, kia whakakahangia ai ngā tīwiri huinga e rua i runga i te papa anga. Hei tauira, ko te tīwiri huinga waea pēhi tapawhā e rua he tīwiri pane paraharaha me te tīwiri huinga papa tapawhā e rua. He mea whakamahi whānuitia ki ngā pito waea mō ngā mahi waea me te whakakoi. 

Te rerekētanga i waenga i ngā tīwiri whakakotahi me ngā tīwiri noa 

(1) Kei te tīwiri whakakotahi he horoi puna tāpiri, he horoi papatahi rānei, ki te whakatauritea ki ngā tīwiri noa, he wāhanga whakakotahitanga toru rānei me te horoi puna tāpiri. Koinei te rerekētanga o te āhua. 

(2) Ngā Rerekētanga o ngā Āhuatanga Ā-ringa. E toru ngā taputapu e titoa ana i te tīwiri whakakotahi, ā, mō te mahi, e toru ngā whakapiripiri e hiahiatia ana kia mahi tahi ai. He haumaru ake, he watea ake hoki te whakamahi i ngā āhuatanga ā-ringa o ngā tīwiri whakakotahi. Ko te painga nui o te whakakotahi i ngā tīwiri ko te mea ka taea e rātou te whakahaere i ngā mahi raina whakaputa kia watea ake, kia pai ake ai hoki, kia pai ake ai te mahi. 

(3) Ngā rerekētanga o te whakamahinga. He whānui ake te whakamahinga o ngā tīwiri noa i ērā o ngā tīwiri whakakotahi. I te nuinga o te wā, ka whakamahia ngā tīwiri noa i roto i ngā hua ahumahi, ā, he pai anake ngā tīwiri whakakotahi ki ngā rauemi hua motuhake. Ina hiahiatia ngā tīwiri me ngā horoi puna me ngā horoi papatahi, ka hiahiatia noa ngā tīwiri whakakotahi i tēnei wā.
