Week 7 - Upper Housing

I tried creating the upper housing and buttons in one part using another surface loft.

I used a 3D sketch and the 'convert entities' tool to copy the top edge of the lower housing part.
I tried using this sketch as a profile for a loft, a boundary surface, a surface fill etc. but always ran into errors.

I solved these problems by splitting it into two sketches; one for each side, symmetrical around the right side plane.

I created a sketch on the right face plane for a profile running across the top of the part.
I drew a series of guide curves; I found I needed lots to make the loft resemble the upper housing, but was still left with a pinched nose and a very wrinkly and uneven surface.

Using the zebra stripes function to check the quality of the surface.

I created another surface, made up of a sweep and a loft, to create the valley detail around the wheel.
