This show the diameter of the bigger circle as the arrows point in at the two far edges of it. By using calculations you can discover the diameter of the bigger circle and also the smaller circle within. This shows the diameter of the inner, smaller circle as it has the two arrows pointing at the two far edges of the inner circle. This line shows as section parts because it cuts straight through the circle, we know it’s not hidden detain because it’s not a consistent dash line it’s only partly broken and not a full line. This shows the 3^rd angle projections. This shows the Angular and Linear measurements of the drawing. This is hatching. I know this because the area has multiple lines such as on hatching. We use hatching to show bits of the object with will be cut out and removed in the production.

THERE IS NO HIDDEN DETAIL

This line shows as section parts because it cuts straight through the circle, we know it’s not hidden detain because it’s not a consistent dash line it’s only partly broken and not a full line. This shows the date it was made. This shows the scale. This shows hidden detail as it is a consistent dashed line, all the other consistent dashed lines are also hidden detail. This line shows as section parts because it cuts straight through the circle, we know it’s not hidden detain because it’s not a consistent dash line it’s only partly broken and not a full line. This is 3^rd angle projection.

THERE IS NO HATCHED AREAS, NO DIAMETER OR RADIUS and NO ANGULAR AND LINEAR MEASUREMENTS.

THERE IS NO DIAMETER OR RADIUS ON THIS DIAGRAM
