Tips for Missing Grid Lines

Here are some tips for things you can check if your grid lines are missing (click on images to enlarge):

1. Is the Grid category turned on?
   Check Visibility/Graphics in the view and make sure that the Grids Annotation Category is turned on.
   
   
   
   
2. Are the grids hidden in the view?
   To see if this is the problem, toggle on the Reveal Hidden Elements tool. If you see the missing grid, select it, right click and choose Unhide in View.
   

   
   
   
3. Is your grids workset opened in the project?
   To check, click the Worksets icon in the Collaborate tab. Verify that your grids workset display Yes in the Opened column.
   

    
   
   
4. Is your grids workset turned on in the view?
   Check the Worksets tab in Visibility/Graphics to see if your Grids workset is turned on in the view. 

    
   
   
5. Do the extents of the grid cross the view in question?
   Datum planes such as grids aren't visible in views if they don't intersect the view's plane. Try going to a view where you can see the grid, right click it, and choose Maximize 3D Extents and see if it shows up in the view in question. A good general rule would be to set up the primary levels before laying out the grid. This will force the display of grids to show on all levels. 

    
   
   
6. Are the grids perpendicular to the view?
   Grids must be perpendicular to views to display. So if your elevation and grid line don't intersect at a perpendicular angle, the grid it won't show up in the elevation.

7. Is your grid line curved?
   Arc grid lines will display in section views where the center of the arc intersects and is perpendicular to the section line.
   

    
    

Another good resource for more information on this topic is in the Datum Extents and Visibility document in the Help menu within the product.

Very useful post. For anybody that runs through this and discovers that its due to grids not been perpendicular to the view or curved, I would recommend this workaround as posted on the Design Re-form website, http://designreform.net/2008/05/revit-missing-grids-in-elevation/
