Tyring to push ahead with my assignments with the feastiveseason approaching! But need a confirmation on this actually quite straight forward question on one of my papers:
Draw a diagram showing the thin and thick edge substances on a toroidal surface of a lens and name the base and cross curves on both the convex and concave surfaces.
Now i have one drawn out but i have no way of uploading it thanks to internet at home being down and using the work pc but any help or direction would be great, i kinda just need to know im on the right track even!:hammer:
