You can hide selected faces on a model such that you are able to see inside the model. This feature is especially useful for bodies with interior cavities, such as engine blocks. To use the feature, first select faces on the model that you want to hide, then right-click anywhere in the Geometry window and choose Hide Face(s) in the context menu. This menu choice is only available if you have already selected faces.

Choose Show Hidden Face(s) from the context menu to restore the visibility of faces previously hidden using Hide Face(s). The Show Hidden Face(s) menu choice is only available if there are hidden faces from choosing Hide Face(s). It cannot be used to restore the visibility of faces previously hidden by setting Visible to No in the Details view of a Named Selection object.
