Select the geometry, and click Modify | <Element> tabMode panel (Visibility Settings).
In the Family Element Visibility Settings dialog, select the views in which you want the geometry to display:
NoteAll geometry automatically displays in 3D views.
If desired, select When cut in Plan/RCP (if category permits).
If you select this option, the geometry appears cut if it is intersected by the cut plane of the view. If the element is cut by a section view, it also shows if you select this option.
Select the detail levels at which you want the geometry to display in a project:
Detail levels are dependent upon view scale.
NoteThe Family Element Visibility Settings dialog is different for families of profiles and detail components. For these families, you can set only the detail level.
TipYou can set family elements to be visible or not visible in the project by associating the Visible parameter of solid geometry tools with a family parameter for that element. The Visible parameter is available for solid and void geometry tools (blends, sweeps, swept blends, revolves, and extrusions). This lets you create one family type with optionally visible geometry on it. Note that the family geometry still exists in the project, it is just invisible. For example, it may still be involved when you join geometry in the project.
