Got a call from a friend today describing a situation he was sorting through. He needs a gridwork to overlay on his project that defines the project much like a map defines each grid cell by the letter on the vertical and horizontal borders. Just like the National Cadd Standard Uniform Drawing System (NCS/UDS) suggests for our sheets. In this case the project is so large that they want this grid to help find parts of the project. So this grid needs to appear in all views possible automatically.
The obvious issue with just using Revit grids in the project itself is that they compete with "real" grids for structural steel etc. The answer? We came up with nesting a separate Revit project with the grid layout. Guess we'll see how well it works as it goes forward. The grid below is a mockup and each square is 150 ft. x 150 ft.
The catch? Since you probably want grid cell labels you need to set up a view for each scale so you can add some text in between each grid. So for each scale view that you need to see the grid in the host project, you create a view and annotation for it. Then in the host file you override the visibility graphics for each view to assign the correct scale view.
