So you can’t see a grid or reference plane in a view that you need it to show up in. What is the problem? Most will check visibility and graphics first, perhaps check to see if the workset is turned on, but what if other grids or references planes are already visible?
We sometimes lose a reference plane or Grid in a view. You’re not crazy; the reference plane just did not get up a walk away. In fact, you can probably see it if you switch to a different view. The problem is that it won’t display in the view you need it to. Most of the time 2 things can fix this problem, both work, it’s up to you to choose how you want to fix it.
The problem could be caused by two things. First, the grid or reference plane you are missing is not at a right angle to the view you would like to show it in. This unfortunately, is only correctable by making the view be perpendicular to the line you want to see. Revit cannot display a grid or reference plane that is not perpendicular to the view. This problem stems from Revits inability to be inaccurate (inaccuracy is not something computers are really good at, nor should you really want them to be).
Revit cannot display the grid because placing a line in that view to represent the grid or reference plane would not show it correctly. Even in a section view, Revit cannot display a grid line at an angle that is not perpendicular to the view. Again, it just doesn’t know how to show line that might not actually be there.
The second reason is much simpler. The grid or reference plane does not touch the cut plane for the view that you want to see it in.
The second example can be fixed by changing the view range for the view you would like it to display in or change the extents of the grid or reference plane. Click here for video explaining all of this
Hopefully, this helps you the next time a grid or reference plane goes missing.
