Are you using this for medical or dental models such as the first example of the dental prosthesis? Zbrush will do those additions but without the ability to relate the thickness to real world measurements. I have done very similar things using Zbrush in conjunction with other programs. As long as you establish a datum, you can govern your dimensions.

If you can be more specific, I'm sure someone can provide a more suitable answer.
