QUICK CHECKLIST
First, make sure it actually exists. Check to see if it is still visible in other views.
Check Visibility/Graphics. Is the object category (and subcategories) ON?
Check Visibility/Graphics. Is there a View Filter changing the way objects are displayed?
Check to order of View Filters. Filters at the top of the list override filters below.
Check Visibility/Graphics. Is the linestyle set to Override?
Check Visibility/Graphics. Is the detail level set to By View?
Check Visibility/Graphics. Are all the worksets ON?
Check Visibility/Graphics. If the object is in a linked file check Revit Links.
Check Visibility/Graphics. Check each Design Option.
Try changing phase and phase filter in View Properties (VP).
Try changing the detail level of the view.
Are all your worksets opened? (it may be hiding in a closed workset).
Is it on the right workset?
Check View Range in View Properties (VP).
Check for Plan Regions if in a floor plan view (they may not be visible).
The object may have been moved to a new elevation.
Check Crop Region and Far Clip settings in View Properties (VP).
Set your view to wireframe. It may be hiding behind a filled region or other object.
Select the Linework tool (set to By Category) and see if it wasn’t hidden with this tool.
If the problem is with a family file open the family and check the visibility of the elements.
CAD FILES NOT VISIBLE
When CAD files are insert "Current View only" they come in as 2D objects, with their Draw Layer parameter set to "Background" by default. So if you can't see the CAD file it is probably behind other things. Change Draw Layer to "Foreground".
If "Current View only" is not ticked the CAD file comes in as a 3D object (even if it is a 2D drawing). The CAD file will exist on the level it is placed at so may be below (possibly hidden by other things) or above your current view's view range. To fix it change the level the CAD file is hosted on.
ITEMS DISPLAYING ON WRONG LEVEL
Model elements located outside the visible range generally are not shown in a view.
The exceptions are floors, stairs and ramps, and components that stay or are mounted on the floor (like furniture) are shown even when slightly below the visible range.
Floors will show up in a view when they are below a bottom range from 0 to 1200. This is a design feature of Revit so that floors slightly below the current level still show in a floor plan.
Elements that are strictly below the cut plane, but are at least partially within the visible range, are shown as viewed from above. For components this means display according to Family objects Element Visibility for Plan/RCP setting.
Walls shorter than 6 feet (approximately 1.83 meters) are not cut, even if they intersect the cut plane.
There are a few categories for which an element located above the cut plane but partially below the top clip is shown in plan. These categories include windows, casework, structural columns and generic models. These objects are shown as viewed from above. To stop this happening lower the top clip plane via View properties, View Range.
Visibility Rules in RCP view are similar to those in plan with the exception that objects are presented as viewed from below and mirrored.
Setting view range depth to a level below the associated level (or unlimited) causes windows and doors to display differently. e.g. lines appear across doorways. Use Linework tool to change extra lines to <invisible lines>.
LEVEL & SECTION MARKERS THAT WON'T DISPLAY, or MOVE AROUND
Check they are on the right workset.
First of all check the view properties and make sure the Phase is same as other windows.
Turn off Crops to see if level references are beyond the crop.
Move your level references and ensure the Annotation Crop boundary includes your level references.
Problem: When you change scales in a view the section or elevation marks disappear.
This is a setting in the properties of the section mark. This is intended to prevent HUGE section marks at scales like 1:1000. To change that parameter Click on section mark, Open Properties, change the Hide at scales coarser than parameter.
Problem: Level Reference change their position in a view automatically:
To move independently in each view you need to select the levels and change them to 2D extents (clicking on the 3D icon when the level is selected). This allows the annotation lines to be dragged independently in each view.
All levels/grids/sections (referred to as datums) have 3D and 2D extents. If the 3D extents of that level don’t cross the 3D extents of the section or the elevation they will not show. Therefore, to make them show you need to adjust them in an elevation/section so they do intersect. To do this:
Draw a new Level.
Switch to the ground floor Plan View.
Draw a Scope Box (Drafting tools) around the project.
In the Properties of the Scope Box give it a name.
In the Properties of the Scope Box edit its visibility settings so it is visible in Elevations (you will do this in the "override" column by selecting "visible" in the elevations rows).
Switch to an Elevation and adjust the top and bottom of the Scope Box to be above and below the project.
Select the new Level drawn at 1.
Right-click the Level and choose \"Select All Instances\".
Press the Properties button.
Under the Scope Box parameter, select the Scope Box created at 3.
The Levels will be constrained to the Scope Box.
Select all Levels and press "Propgate Extents" and choose all relevant Views.
Switch to an Elevation view at 90deg and repeat step 12.
If desired, remove the Scope Box (it can be safely left there as it will not print by default).
As a last resort right click on the datum in a view it does display in and select maximise 3D extents it will expand the extents to the full boundaries of your model, which makes it show up in all views at full extents.
