 ====== Entering Inertial Values Using Expressions ======
-It is possible to include any regression equations for the inertia and center of mass because Visual3D allows the user to put expressions into the edit boxes. Consider a typical right thigh segment, which is populated with the default inertial values.

 ===== Example: Frustra of Right Cones =====
-For the sake of this example, we will create an expression for the Axial component of the center of mass based on the default computations described elsewhere in the documentation
+In this example we consider a conical segment:
