Michael,

Thanks for the info. I am modeling the leg as a separate item. The leg model will be exported as a STL file into Aspire to generate tool paths for my CNC. The top can be model in Aspire very easily. The issue is making the "Maloof" joints between the top and legs. Those joints need to fit together like a hand in a glove. I have no doubt MOI can do what I need. The issues is my lack of experience with the program. I downloaded the 90 day trial of Rhino and found that program is simply way to complex to learn in a reasonable amount of time.
