Angular Layout by Using a Ruler

This form of angular layout is generally not shown as an angle on the drawing. It just shows the distance from a corner along with the two adjacent sides. Figure displays a typical layout using a ruler. The corner A is the just only one that doesn't illustrate an angular dimension.

Figure: Layout

The process for laying out angle by using a ruler is as follows:

(1) Eliminate all burrs and clean the face of the work-piece.

(2) Apply the layout dye to the surface to be laid out.

(3) Compute 1cm from the corner along the two sides by using a ruler and scribe the line on each edge.

(4) Join these points along with the edge of the ruler.

(5) Lightly mark this line at interval of 6 to 9 mm through using prick punch.
