Using Layers to Filter Entities (Viewer)

Drawings may contain several transparent Layers. The entities of a complete drawing are onto different Layers. The Layers, imposed on top of one another, form the entire drawing. Layers aid in visualizing the part or drawing. You can display or hide entities using Layers.

Layer Visibility

An advantage of Layers is that they aid in visualizing the part or drawing. Improve the clarity of a drawing by choosing Layers and hidding drawing entities.

You can control the visibility and the influence of entities within the Layer.

Switching the layer on and off
When a Layer is shown, the entities on it are visible. Entities on hidden Layers are invisible.
Freezing and thawing Layers
A frozen Layer is invisible and protected and thus impossible to change. A frozen Layer is not included when you rebuild a drawing. When working with complex drawings, freezing unneeded Layers can increase performance. When you thaw a Layer, it becomes visible and you can make changes to it.

The Layers Palette

Use the Layers palette to view and filter the layers of the drawing.

The Layers palette displays the list of layers from the current drawing.

The first column indicates the Layer's LineColor.
The button symbol indicates whether the Layer is shown or hidden. You can turn each Layer on or off independently.
The button symbol indicates whether the Layer is frozen or thawed. You can freeze or thaw each Layer independently.
In drawings with many Layers you can search for a specific Layer if you know a portion of the name.
