I need a program to make a 3D drawing easy and carefully at a half of a day.
3D drawing consists of:
3 arcs for angle between two vectors or lines vector,
4 vector, line, arc labels.
1 Greek symbols (phi, alpha, theta, ...)
2 showing a fraction ability (phi/2)
3 font style such as italic, bold, ...
I need to insert this drawing in my paper, but it will be great if an editor allow to watch the image in 3D.
