Do you want to make your Revit modeling experience more convenient and efficient? One way to achieve this is by making levels visible in the 3D view. Here's how you can do it.

1. Open the 3D View: First, open the 3D view that you want to work with in Revit. This can be an existing 3D view or you can create a new one specifically for this purpose.

2. Visibility/Graphics Overrides: Once you have the 3D view open, go to the 'View' tab on the ribbon and click on the 'Visibility/Graphics' button. This will open the Visibility/Graphics Overrides dialog box.

3. Modify the Visibility/Graphics Overrides: In the Visibility/Graphics Overrides dialog box, you will see a list of categories and subcategories of elements that are visible in the 3D view. Look for the 'Levels' category and make sure it is checked. If it is not checked, simply tick the box next to 'Levels' to make them visible in the 3D view.

4. Adjust Display Settings (Optional): If you want to further customize the display of levels in the 3D view, you can click on the 'Override' button next to the 'Levels' category. This will allow you to modify the color, line style, and other display settings for the levels in the 3D view.

5. Apply and Close: After making the necessary changes, click 'OK' to apply the modifications and close the Visibility/Graphics Overrides dialog box. You should now be able to see the levels in the 3D view.

By following these simple steps, you can make levels visible in the 3D view in Revit, which will help you better understand the spatial relationships in your model and improve the overall clarity of your design. Try it out and see the difference it makes in your modeling workflow!
