NOTE

REVISION OF ISOMETRIC CIRCLES

Isometric circles, also known as isocircles, are geometric shapes often encountered in technical drawings and computer graphics. In isometric projection, these circles appear as ellipses due to the distortion caused by the viewing angle.

Isometric drawings include three axes: one vertical axis and two horizontal axes that are drawn at 30 degree angles from their true position. The application of this type of drawing extends to many fields, such as engineering, mechanics, physics, and architecture.
