At times, you may come across a scenario where you have a floor plan with various windows, but some might be missing because they are situated at different heights. In this case, the Revit Plan Region feature is very useful as it lets you define multiple cut planes within the same floor plan.
Plan Regions in Revit consists of closed sketched lines in any shape required for your floor plans. Elements enclosed in this area can be assigned a different view range with another cut plane and height. Using this feature allows you to improve the clarity of floor plans by showing elements at heights beyond the view range of the rest of the floor plan.

In this article, I will explain the basics of Plan Region in Revit, how to create a Plan Region, and how to configure its view range and visibility settings.
Revit allows you to effortlessly create floor plans for each level using a specified view range that applies to the entire view. Sometimes you might come across a design with a split level with windows at different heights. For example, some hopper windows may not be visible in the floor plan. This is when the Plan Region in Revit becomes useful.
In short, a Plan Region can be used to define new top, bottom, and cut planes in a floor plan that already has a view range. Plan Regions consist of closed sketch lines in any shape you need for your floor plan. The regions cannot overlap each other, but the lines can coincide.
Most Revit users, use the Plan Region to control the visibility of hosted elements such as windows and doors. This function has a restriction when it comes to MEP model elements because you cannot control the visibility using the Plan Region.
TipYou can easily copy and paste Revit Plan Regions within or between views as they are specific to each view. The view range settings for the Region will remain the same as the ones you copied from.
Create Plan Region Revit
To ensure that elements with varying height settings are visible, you can create a Plan Region in your floor plan. This method works for elements that are above the cut plane or below. Make sure to open a plan view and follow the steps outlined below:
- Open the View tab > Create panel
- Click Plan Views
- Select Plan Region from the dropdown menu
- From the Draw panel take a drawing tool
- Draw a closed loop in any shape you require
- Click Finish to create the Plan Region
After you finish the Plan Region you might notice the green boundary lines (default settings) but the elements are still not visible. This is because we haven’t set the view range yet. The Plan Region settings adopt the same settings from the view it is in.
Now that you have placed the Plan Region we can continue by modifying its view range. To change these settings open the view containing the Plan Region and follow the steps written below:
- Select the Plan Region
- Go to the Modify | Plan Region tab or the Properties Browser > Click View Range in the Region panel or Edit… in Properties Browser > View Range dialog opens
- In the View Range dialog, change the settings to your requirements
- Click Apply or OK
After you apply the view range settings the view changes immediately. In the example above I only changed the Top range to make the window visible. Of course, it is possible to change the Cut plane level and Offset. This is particularly useful when working with split levels in Revit.

Plan Region Visibility and Appearance
There are various ways to modify the appearance and visibility of the Plan Regions. However, the most commonly used approach to control this for Plan Regions is with the visibility/Graphic Overrides settings. Using this method allows you to change the settings for the whole view.
- Open the View tab > Graphics panel
- Click Visibility/Graphic Overrides (Shortcut: VV) > Visibility/Graphic Overrides dialog opens
- In the Visibility/Graphic Overrides dialog, click on the Annotation Categories tab
- In the Visibility column search for Plan Region > Click Override… in the Projection/Surface Lines column > Line Graphics dialog opens
- Change the appearance settings in the Line Graphics dialog
- Click OK when finished
You can turn off the visibility of Plan Regions by unchecking [A] the box inside the Visibility column of the Visibility/Graphic Overrides dialog.
When a Plan Region is visible inside your view while exporting or printing to PDF or CAD format, it will be visible in your output. To disable the visibility of Plan Regions in the output, you can either hide them or turn off the settings in the print or export function.
To prevent Plan Regions from being exported or printed, select the Hide ref/work planes option in the Print Setup menu. For CAD formats, you can do the same by selecting the Hide reference planes option.
TipCreate a View Template to display Plan Regions on your floor plan. The visibility of Plan Regions can be toggled by selecting different View Templates. Learn more about View Templates: View Template Revit – Everything you need to know.
The Revit Plan Region feature is a helpful tool for refining floor plans, especially when dealing with doors and windows at different heights. Plan Regions are closed boundaries that can be used to control the visibility range within them.
To manage Plan Regions inside the views, you can use the Visibility/Graphic Overrides settings to hide, unhide, or change their appearance. When exporting your design in 2D, keep in mind that you can adjust the settings to include or exclude Plan Regions in the output.
