Ellipse

Umarnin ellipse yana zana ellipse ta amfani da dannawa uku: tabon tsakiya, ƙarshen semi-axis na farko (babba) a kowace kusurwa, da tsawon semi-axis na biyu (ƙarami). Axes biyun koyaushe suna ta hankalta da juna — ana samun shugabancin axis na biyu kai tsaye daga na farko.

Zana ellipse

Rubuta ellipse a tashar umarni ko danna maɓallin kayan aiki na Ellipse.
Danna tabon tsakiya, ko rubuta X,Y ka danna Enter don daidaitawa madaidaiciya.
Danna ƙarshen axis na farko — yana saita duka shugabanci da tsawon semi-axis na farko. Shigar da daidaitawa yana aiki a nan ma.
Saita tsawon axis na biyu — motsa mai nuni ta hankalta a kan axis na farko, sannan danna ko rubuta tsawo.

               ● ← ƙarshen axis na farko (mataki na 3)
              /
  tsakiya ●  /  ← axis na farko (kowace kusurwa)
            |
            ● ← mai nuni a nan yana saita tsawon axis na biyu (mataki na 4)

Ana sanya ellipse bayan mataki na 4 kuma umarnin yana fita.

Shigar da axis — dannawa, daidaitawa, ko tsawo da aka rubuta

Tsakiya (mataki na 2): danna ko rubuta X,Y don matsayi madaidaici.

Ƙarshen axis na farko (mataki na 3): danna, ko rubuta X,Y don daidaitawa madaidaiciya. Kulle-kusurwa kuma yana snap zuwa matakan 45° — yayin an kulle, rubuta tsawo ka danna Enter don sanya ƙarshen a wannan nisan daidai.

Axis na biyu (mataki na 4): tsawon da aka rubuta koyaushe akwai — babu bukatar kulle-kusurwa. Shugabanci an riga an kwaɓe shi ta hankalta a kan axis na farko; rubutu yana saita tsawon kawai.

Gyaran grip — sake girma na axis mai zaman kansa

Ellipse da aka zaɓa yana nuna grips guda biyar:

Grip	Adadi	Aikinsa
Tsakiya	1	Yana motsa dukkan ellipse; axes biyun basu canzawa
Ƙarshen axis babba	2 (ƙarshen adawa na axis mafi tsawo)	Ja don sake girman tsawon semi-axis babba; girman axis ƙarami cikakke yana ci gaba da tsaye
Ƙarshen axis ƙarami	2 (ƙarshen adawa na axis mafi guntu)	Ja don sake girman tsawon semi-axis ƙarami; axis babba ba ya canzawa
