How to Hide Layers in Revit: A Comprehensive Guide for American Users

Understanding and Managing Visibility in Revit

For anyone working with Revit, whether you're a seasoned architect, a diligent engineer, or a detail-oriented designer, managing what you see on your screen is crucial for efficiency and clarity. Often, users new to Revit or those transitioning from other software might refer to "layers" in a way that doesn't directly map to Revit's terminology. In Revit, we talk about "visibility" and "graphics overrides," but the concept of hiding specific elements or categories, much like hiding layers in other CAD programs, is very much a core functionality.

This article will guide you through the various methods of effectively hiding elements in your Revit projects, ensuring you can focus on what's important at any given moment. We'll cover the most common scenarios and provide clear, step-by-step instructions.

The Core Concept: Visibility/Graphics Overrides

Revit's primary tool for controlling what appears in your views is the Visibility/Graphics Overrides dialog box. This is where you'll spend most of your time when you need to hide or display specific categories of model elements, annotation elements, imported categories, and more.

Accessing Visibility/Graphics Overrides

There are a few ways to open this essential dialog:

• From the View tab on the Ribbon, click Visibility/Graphics in the Graphics panel.
• Use the keyboard shortcut VG or VV.

Hiding Elements within Visibility/Graphics Overrides

Once the Visibility/Graphics Overrides dialog is open, you'll see several tabs:

• Model Categories: This tab controls the visibility of all model elements, such as walls, doors, windows, structural framing, etc.
• Annotation Categories: This tab controls the visibility of annotation elements, like dimensions, text, tags, symbols, etc.
• Imported Categories: This tab controls the visibility of linework and elements imported from other CAD software.
• Analytical Model Categories: For structural analysis models.
• Worksets: If you are using worksharing, this tab allows you to control the visibility of elements on different worksets.

To hide a category:

1. Open the Visibility/Graphics Overrides dialog (VG or VV).
2. Navigate to the appropriate tab (e.g., Model Categories for walls).
3. Locate the category you wish to hide in the list.
4. Uncheck the checkbox next to the category name.
5. Click Apply to see the changes in your view without closing the dialog, or click OK to apply and close the dialog.

Hiding Specific Instances or Types

While Visibility/Graphics Overrides is powerful for hiding entire categories, sometimes you need to hide individual elements or specific types of elements without affecting the entire category.

Hiding Individual Elements (Temporary Hide/Isolate)

This is a very common and useful method for temporary adjustments:

1. Select the element(s) you want to hide.
2. On the View tab, in the Graphics panel, click Hide in View. You'll see two options:
   • Elements: This will hide the selected element(s) in the current view only.
   • Category: This will hide all elements of the same category as the selected element(s) in the current view.

To temporarily unhide these elements:

1. At the bottom of the view window, you'll see a pair of glasses icon. Click on it and select Temporary Hide/Isolate.
2. Choose Reset Temporary Hide/Isolate.

To permanently hide elements (which creates a filter):

1. Select the element(s).
2. Click Hide in View > Elements.
3. This action creates a new filter that is automatically applied to the view. You can manage these filters by going to Visibility/Graphics Overrides > Filters tab. Here you can edit, delete, or disable the filter.

Hiding by Element Type

If you want to hide all instances of a specific element type (e.g., all "Double Hung" windows), you can do so through Visibility/Graphics Overrides:

1. Open Visibility/Graphics Overrides (VG or VV).
2. Go to the Model Categories tab.
3. Find the category containing the element type you want to hide (e.g., "Doors").
4. Click the Edit... button next to the category name.
5. In the dialog that appears, uncheck the specific Family Types you wish to hide.
6. Click OK on all dialog boxes.

Controlling Imported CAD Layers

When you import CAD files into Revit, they often come with multiple layers. You can control the visibility of these imported layers individually within Revit.

1. Open Visibility/Graphics Overrides (VG or VV).
2. Go to the Imported Categories tab.
3. You will see a list of all imported CAD files in the view. Expand the imported file you want to manage.
4. Each layer within that CAD file will be listed. Uncheck the checkboxes for the layers you wish to hide.
5. Click OK.

Hiding Elements in Specific Views (View Templates)

For projects with many similar views (e.g., multiple floor plans at the same level), using View Templates is an incredibly efficient way to manage visibility settings. Once you've set up the visibility for one view, you can apply that template to other views, ensuring consistency.

1. Open the view you've configured with the desired visibility settings.
2. In the Properties Palette for the view, scroll down to the Identity Data section.
3. Under View Templates, click the button (usually says "None" if no template is applied).
4. In the View Templates dialog, you can either:
   • Create a New Template from the current view's settings.
   • Edit an Existing Template to apply changes to all views using that template.
5. When creating a new template, give it a descriptive name (e.g., "Architectural Floor Plan - No MEP").
6. You can choose which properties of the template are editable when applied to a view. For visibility, ensure "Visibility/Graphics Overrides" is checked.
7. Once a template is created, you can apply it to other views by selecting the view, going to its Properties Palette, and choosing the template from the dropdown.

Using Filters for Advanced Visibility Control

Filters are a powerful way to selectively hide or override the graphics of elements based on their parameters. You can create custom filters to hide elements that meet specific criteria.

1. Open Visibility/Graphics Overrides (VG or VV).
2. Go to the Filters tab.
3. Click Add...
4. Click Create Filter...
5. Give your filter a descriptive name (e.g., "Hide Non-Load Bearing Walls").
6. Under Category, select the category you want to filter (e.g., "Walls").
7. Under Filter Rules, define your criteria. For example:
   • Parameter: Is Exterior Built-in Wall
   • Operator: Equals
   • Value: No
8. Click OK to create the filter.
9. Back in the Filters tab of Visibility/Graphics, select your newly created filter.
10. In the Visibility column, uncheck the checkbox to hide all elements that match your filter criteria.
11. Click OK.

Best Practices for Managing Visibility

• Be Consistent: Use View Templates to maintain consistent visibility settings across similar views.
• Name Appropriately: When creating custom filters or templates, use clear and descriptive names.
• Understand the Difference: Differentiate between temporary hides and permanent hides (which create filters).
• Organize Your Worksets: If using worksharing, organize your project elements into logical worksets and manage their visibility accordingly.
• Regularly Review: Periodically review your visibility settings to ensure they are still relevant and efficient for your current task.

By mastering these techniques, you can significantly improve your workflow in Revit, making it easier to navigate complex models and present clear, focused views of your designs.

Frequently Asked Questions (FAQ)

How do I make hidden elements reappear in Revit?

The method to make hidden elements reappear depends on how they were hidden. If you used "Temporary Hide/Isolate," click the glasses icon at the bottom of the view and select "Reset Temporary Hide/Isolate." If elements were hidden permanently (via Visibility/Graphics Overrides or by creating a filter), you need to go back to the Visibility/Graphics Overrides dialog (VG or VV) and re-check the relevant category or disable/delete the filter. For elements hidden using "Hide in View" > "Elements," you'll need to find the corresponding filter in the Filters tab of Visibility/Graphics Overrides and re-enable its visibility.

Why can't I see certain elements in my Revit view?

There are several reasons why elements might not be visible. They could be hidden due to Visibility/Graphics Overrides settings for their category, a filter applied to the view, or they might be on a workset that is turned off. Additionally, elements might be outside the view's crop region, or their phase settings might not align with the view's phase. Always start by checking the Visibility/Graphics Overrides dialog (VG or VV).

What's the difference between hiding elements and deleting elements in Revit?

Hiding elements is a visual control that makes them disappear from a specific view or set of views without removing them from the project's database. They can be easily unhidden. Deleting elements permanently removes them from the project. Once an element is deleted, it cannot be unhidden; you would need to recreate it or use a backup of your project file.

How do I control the visibility of imported CAD details?

To control imported CAD details, open the Visibility/Graphics Overrides dialog (VG or VV), navigate to the "Imported Categories" tab, select the imported file, and then uncheck the specific layers within that CAD file that you wish to hide. You can also use filters for more complex control over imported elements.
