Igicapo cyibumba cya plastiki gishobora kuba gikozwe muri 45 # ibyuma, bizimya kandi bigashyuha kugirango byongere imbaraga zo kwambara.Imyanya yimyanya iyobora irashobora kuba imbere cyangwa inyuma, ishobora kugenwa neza ukurikije ubunini bwikibumbano.Nyamara, inguni n'uburebure bwa oblique bayobora inkingi bigomba kugenwa ukurikije intera igenda ya slide;muri rusange, inguni ya oblique iyobora inkingi ni 20 ° cyangwa 25 °.Kugena inguni ihamye birashobora koroshya umusaruro wicyuma cya pisine, kugirango wirinde gukenera buri gihe.Gukora amahembe yegamiye impande zitandukanye.Koresha amategeko ya cosine yimikorere ya trigonometrici kugirango ubare uburebure bwa post ya oblique.

Hariho ubwoko bwinshi bwo kuvura hejuru yububiko, ibisanzwe ni ubuso bworoshye nubuso bwa pockmarked, nizo ngaruka zo hejuru zigomba gukorwa ukurikije ibyo umukiriya yahisemo.
Urwego urwo arirwo rwose rurangiza muruganda rwacu rushobora gukoreshwa.

Urufatiro rusanzwe rusobanura ko ibishushanyo mbonera bikozwe mu bikoresho bya P20, naho ibishushanyo bikozwe mu ikoranabuhanga ryerekana indorerwamo.Mubisanzwe bikoreshwa muburyo bwo kohereza hanze.Ibyiza byo gukoresha ni uko niba hari ikibazo kijyanye nububiko, birashobora gusanwa gusa mugusimbuza ibice, nibyiza.
