Hello Michael.

@You : "...One thing to note is that the surfaces involved in the pocket are a lot more complex than they seem..."

Hmmm....very interesting...

@You : "...I'd probably recommend doing a boolean of a box to make this indentation instead of Inset..."

Many thanks for your help! :)

@You : "...Did you need any help to finish the model? It sounded like you were able to get a good result on it from Rhino..."

You already helped me with your reply.
Usually I much prefer to use Moi over Rhino :)

Thanks. I will let you know the results with the fillets after the boolean operation.
