Utilizing Layers in Assembly Models

Unlike parts, you can add components to layers in an assembly and hide the geometry of those components.
• Add almost any feature to a layer.
– Only non-solid geometry is hidden.
• Add assembly components.
– Solid geometry is hidden.
• Cascading layer control available for layers of same name.
• Placing external items options.

Utilizing Layers in Assembly Models
Similar to parts, you can hide non-solid geometry of assembly features including assembly datum features and surfaces. For example, if you create an assembly level hole, add it to a layer, and then hide the layer, the hole geometry still displays, while the hole axis is hidden.
Unlike parts, you can add components to layers in an assembly. If you add components to a layer and then hide the layer, the component geometry hides. In Figure 2, the nut and bolt components were added to the HARDWARE layer and hidden. Notice that the components are removed from the display in the graphics window.
Cascading Layer Control in Assemblies
Layers in assemblies provide cascading control. You can control a part level layer from an assembly if the part and assembly both contain a layer of the same name. When this circumstance occurs, you can edit the layer properties and layer display of each component individually, as shown in Figure 1.
