Descriere

Acest instrument desenează un arc de cerc definit prin 3 puncte: punctul de start, punctul final și un alt punct de pe arcul de cerc.

Cum se folosește

See also: Drawing aids.

Când instrumentul este activat, indicatorul maouse-ului se schimbă într-o curuce albă cu o iconiță formată dintr-un arc de cerc roșu. Coorodnatele indicatorului sunt afișate alături în culoarea albastră în timp real.

• Selectați punctele într-o zonă liberă din vizualizarea 3D, sau pe un obeict existent (auto constrângerea poate fi activată în TaskView).
• Apăsați Esc sau click drepta butonul mouse-ului pentru a abandona această funcție.
