Structure View

In Building and Civil Assemblies, a 3D Design-Structure View switch is available in the BIM section of the action bar.

Structure View
Dedicated to working on structure, lets you edit and navigate structures as well as compose your environment using search and insert capabilities. Available in the product world only, 3D parts and products are visualized on turntables. For specialized product types with no associated geometry (under Types in the New Content dialog box), a thumbnail (simplified representation) of the type is displayed.
