Ketiv's Modern Medium Library has been converted into Vasari families and made available on the Web. Modern Medium families cannot be altered structurally within Vasari. You can, however, change the appearance of a Modern Medium family type by changing the render appearance of the material linked to its object style.
For example, you could download and load a Modern Medium piano so the family displays under Families\Specialty Equipment in the Project Browser. To change the color to natural wood, you can create a new material called Piano, and then select the color and texture desired. The appearance of the piano will change after you apply the new material to the object style of the piano.
