Umurongo woherezaInguni y'icyuma, kandi ibyingenzi byingenzi bifata inguniumunara w'icyuma, aribwo buryo bwo gushyigikira umurongo wohereza hejuru kandi ushyigikira kiyobora hamwe ninsinga zubutaka. Iremeza ko kiyobora yujuje intera isabwa kuva hasi nibintu, kandi irashobora kwihanganira umutwaro wuyobora, insinga zubutaka n'umunara ubwawo, kimwe n'imizigo yo hanze.Icyuma, bizwi cyane nka angle angle, ni umurongo muremure wibyuma impande zombi zikora inguni iburyo. Hariho ibyuma bingana ibyuma hamwe nicyuma kingana.Inguni inganas bifite ubugari bungana kumpande zombi. Ibisobanuro byayo bigaragarira muri mm ibipimo by'ubugari × ubugari × ubugari. Kurugero, "∟30 × 30 × 3" bisobanura icyuma kiringaniye gifite ubugari bwa mm 30 n'ubugari bwa mm 3. Irashobora kandi kugaragazwa nicyitegererezo, ni, ubugari, muri santimetero, nka ∟3 #. Umubare wikitegererezo ntugaragaza ibipimo byubunini butandukanye muburyo bumwe, bityo ubugari nubunini bwibyuma byinguni bigomba kuzuzwa kumasezerano nizindi nyandiko kugirango wirinde gukoresha nimero yicyitegererezo wenyine. Ibisobanuro byibyuma bishyushye bingana impande zingana ni 2 # -20 #. Inguni irashobora gukusanyirizwa mubice bitandukanye bitera guhangayika ukurikije ibikenewe bitandukanye, kandi birashobora no gukoreshwa nkibintu bihuza ibice.

Ubumenyi bwibanze nibisabwa tekinike kuriumurongo wohereza inguni umunaraIgishushanyo kirimo ibintu byinshi nko guhitamo ibikoresho, ingano yibigize, igishushanyo mbonera, ibisabwa byo kubaka, no gutegura gushushanya. Ibishushanyo birimo ibishushanyo rusange n'ibishushanyo mbonera. Igishushanyo mbonera kigomba kugabanywamo ibice nkibice, amaboko yambukiranya, imibiri yumunara, namaguru y umunara. Mu bishushanyo mbonera, usibye ibice bisanzwe nkaBolt, flanges, amasahani yomeka, ibirenge byogeshejwe, ibice byose bigomba kubarwa.
