I begun modelling the sunglasses for the final assessment. I begun with the trim piece because it is the pivotal component that all the others are modeled around. I am quite impressed how quickly they are coming together now that I am not watching tutorials as I model.
I made the trim piece by projecting a curve and then filling the surface. I then projected a second curve for the back which is slightly skewed to one side of the front. I lofted these two surfaces to get the trim. I tested this a few times to see how the bridge looks once it is mirrored and adjusted the curve accordingly.
I made the rim by making a boundary surface based off the trim curve and cutting it with a sketch of the rim taken from my 1:1 model photo. I used the offset surface command repeatedly to create the rim and then the lens to fit inside. Once I had both the rim and the lens I created another part that is the same width as the rim the whole way along and used this to make a cavity in the trim so that the rim can slide in perfectly with the lens inside.
My design does not have separate nose grips like the smooth operators did so I had to figure out how to make the rim shape into the correct position to grip the nose. I did this using the freeform command and a lot of trial and error. I had not used this command much before but I eventually got to a stage where I was pretty happy with the result.
