Zana polygon na yau da kullum
Polygon na yau da kullum yana da gefuna da kusurwoyi daidai: hexagon don nut, octagon don alama, pentagon don yanke na ado. A KulmanLab shi ne umarnin Polygon.
- Rubuta
Poligona tashar umarni, ko ka yi amfani da maɓallin Polygon a cikin kwamitin Shapes. - Shigar da adadin gefuna — kowace cikakkiyar lamba daga 3 zuwa 1024 — ka danna Enter. Umarnin yana zuwa da adadin da ka yi amfani da shi na ƙarshe.

Sakamakon polyline ɗaya ce a rufe, don haka duk abin da za ka iya yi da polyline — motsawa, juyawa, offset, sauya girma — yana aiki.
Tsakanin fuskoki ko tsakanin kusurwoyi?
Nan ne mutane ke tuntuɓe. “Radius” na iya nufin nisa biyu daban-daban, kuma ana bayyana hexagon da ɗaya ko ɗayan dangane da abin da kake zana:

| Inside a kashe | Tsakiyar kowane gefe | Siffa mai faɗin tsakanin fuskoki da aka bayar — nut, kan bolt, girman spanner |
Danna I a umarnin radius don canjawa. Ana sayar da hex nut da faɗinsa tsakanin fuskoki, don haka yi amfani da Inside a kashe ka rubuta rabin sa. Don M8 nut mai 13 mm tsakanin fuskoki:

Fuskokin suna da nisan 13 mm daidai; kusurwoyin suna kai 7.51 mm daga tsakiya, kusan 15 mm tsakanin kusurwoyi. Idan ka rubuta radius maimakon danna, polygon yana zama da gefensa na ƙasa a kwance, tsaye a ƙasa. Idan ka danna, yana ɗaukar alkibla daga inda ka danna.

Zana da’irar bolt
Da’irar bolt — “PCD” a zane-zane — zobe ne na ramuka a nesa daidai a kewayen tsakiya. Kana zana rami ɗaya ka maimaita shi. A KulmanLab wannan shi ne ArrayPolar.
Ɗauki ramuka shida na 6.6 mm a kan diamitan pitch circle na 50 mm, a tsakiyar asali:
