Element transparency is a display setting that lets you apply transparency to elements in a model. Transparency may vary from 0% to 100%. A value of 0 indicates no transparency at all, while a value of 100% indicates almost complete transparency.

When transparency is applied to a

• Reference, it includes all elements in that reference.
• Level, it includes all elements on that level.

Elements, references, and levels can have different transparency values assigned to them. If different transparency values are assigned in multiple places, the formula below calculates the effective transparency:

Effective transparency = 1 - (1 - level transparency) * (1 - element transparency) * (1 - reference transparency)
