Technical Drawing - Oblique Projection

In oblique projections, the projectors are perpendicular to each other but are not parallel to the plane of projection.

Circles, circular arcs, and other curved surfaces may be drawn using offset measurements.

In general, all types of sections for isometric drawing may be applied to oblique drawing.

In an oblique drawing, when an angle is specified in degrees in a receding plane, you should convert the angle into circular measurements.

In CAD, oblique drawings are difficult to create because you cannot use snap increments or draw similarly to drawing on grid paper.
