About Visibility States

You can modify the set of entities displayed in a CustomBlock reference using visibility elements and visibility states.

A visibility state is a property of the CustomBlock that specifies which entities of the CustomBlock appear in the Block reference.

For example, you can use a single CustomBlock with two visibility states (V1 and V2) to represent rectangular and round tables. Each visibility state displays the corresponding geometry, as follows:

• V1 displays the circle
• V2 displays the rectangle.

At creation time, a Block reference displays the entities from the default visibility state. You can use the visibility grip point to specify another visibility state.
