A good example of using the ability to hide cached elements is in sections where elements in the distance reduce the clarity of the drawing. In this obvious example, windows cills at a lower height than the window being cut have equal prominence to the cill that is actually cut by the section.
Single instances can easily be hidden by right-clicking.
Multiple instances can be hidden by selecting the element to hide then running the key-in 'reference visible edges cached hide'.
To reveal hidden cached elements either key-in REFERENCE VISIBLEEDGES CACHED HIDDENTOGGLE or highlight the relevant references in the Reference Dialog and toggle on the 'Display Hidden Elements From Visible Edge Cache' setting. Hidden elements will be highlighted, unhidden elements will be greyed out:
Right-click and pick 'Unhide Cached Element' for each element.
The Copy/Hide Cached Element option goes further. The selected elements are both hidden and copied to the active file. The copied elements can then be modified as required.
If a Cached view is changed back to Dynamic hidden cached elements will be un-hidden as the information about what elements are hidden will be lost. Always use the update/synchronize cache tools to update the content.
