Drawing Oblique CrateStart the oblique view by drawing a crate to fit the clock into.

For Standard Grade drawings the depth of the crate should be drawn at 45o with the size measured at either full size or half full size. In this case half sizes have been used.
In this case the size of the crate will enclose the body of the clock but does not include the clock face. This will be added to the main drawing later.

Draw a 45o line through each centre to find the tangent points where the curves are joined by straight edges.
Project the centre of the curve back at 45o to locate the centre of the back curve.
