When working in Autodesk Revit, clarity in visual representation is paramount—especially in complex architectural, structural, or MEP models. One useful technique for enhancing drawing readability or providing visual hierarchy is halftoning. By making certain elements appear subdued or “grayed out,” you can highlight more relevant components while still showing the context. This makes halftoning an essential presentation and coordination tool. Whether you’re preparing construction documents, presentation views, or modeling in collaboration with other disciplines, learning how to halftone a family in Revit can significantly enhance your workflow.
TL;DR: Halftoning a family in Revit allows you to visually de-emphasize elements by making them appear semi-transparent or gray in your views. This can be achieved using Visibility/Graphics Overrides, View Templates, or custom parameters. You can apply these settings to individual instances, types, or entire categories for maximum flexibility. Mastering this technique improves design clarity, especially in shared or detailed views.
What Is Halftoning and Why Use It?
Halftoning in Revit refers to applying a visual override that reduces an object’s visual prominence in a view. This is often used to:
- Show existing conditions faded compared to new construction
- Diminish background elements like linked models
- De-emphasize certain categories in complex views
- Highlight design changes or focus areas
In Revit, halftoning typically results in a gray, semi-transparent effect. It can be applied at the project-wide level, per view, or even per element depending on the level of control you need.
Step-by-Step: How to Halftone a Family in Revit
Step 1: Open the View You Want to Modify
Navigate to the plan, section, elevation, or 3D view where you wish to apply the halftone. Remember, halftoning is a view-specific visual setting unless applied via View Templates.
Step 2: Access Visibility/Graphics Overrides
Press VG or go to the View tab > Graphics panel > Visibility/Graphics (or press shortcut VG). This dialog box is your primary control panel for adjusting the visual style of categories, filters, and imported elements.
Step 3: Locate the Family Category
Within the Visibility/Graphics dialog, find the family you want to halftone by browsing the appropriate category list (for example, Furniture, Doors, Casework, etc.). If you’re not sure which category the family belongs to, you can click on the family in the model and look at the Properties palette.

Step 4: Apply Halftone Option
Once you’ve located the category, check the box in the “Halftone” column. This applies a halftone effect to all elements under that category within the current view.
Note: If you only want to apply the halftone to specific families or types and not the entire category, continue to the next step for a more refined method using filters.
Step 5 (Optional): Use Filters for More Control
If your model has multiple families under the same category, and you only want to halftone one of them, follow these steps:
- Create a new parameter or use an existing one (e.g., “Halftone Control”) in the family.
- Assign a unique value to the family instance or type that you wish to halftone (e.g., “Yes” or “Halftone”).
- Go back to Visibility/Graphics > Filters in the view.
- Add a filter that looks for the parameter with a specific value (“Halftone Control = Yes”).
- In the filter settings, enable Halftone and optionally override line color or pattern.
This method gives you much finer control over which families are halftoned and can be reused across multiple views.
Step 6: Apply View Templates (Optional)
If you want to standardize the halftone effect across multiple views (sections, elevations, floor plans), use View Templates. Here’s how:
- Go to View tab > View Templates > Manage View Templates.
- Create or edit a template, then access the Visibility/Graphics Overrides within it.
- Apply the same halftoning method—by category or filter—as above.
- Assign the View Template to desired views to maintain consistency.
[h3]Alternate Method: Halftoning with Linked Models[/h3]
Are you working with a linked model (such as structural or MEP data)? You can halftone an entire link to set it apart from your primary model:
- Open Visibility/Graphics (VG).
- Go to the Revit Links tab.
- Select the link and click Custom or By Host View depending on your control preference.
- Enable Halftone for either the entire link or specific linked categories using filters or overrides.
This approach is perfect for coordination drawings, where you want to differentiate between architectural and engineering components.
[h3]Tips for Effective Halftoning[/h3]
- Combine halftoning with color overrides to create more interesting or clear visuals (e.g., gray + dashed lines).
- Use View Filters to target tags and annotations as well as model elements.
- Test printing: Always print a test sheet to see how halftones appear on paper or PDFs, especially if issuing final documents.
- Halftone clarity may vary depending on your visual style (Hidden Line, Shaded, etc.).

Common Mistakes to Avoid
- Trying to halftone instances directly: Revit typically requires view-level or category-based overrides for halftoning.
- Not using filters for specific families: Applying halftone to an entire category can affect unrelated elements.
- Overusing halftone: Too many halftones can make your drawing look washed out—use strategically.
- Forgetting about templates: Applying settings view-by-view can be inefficient; use templates for consistency.
Final Thoughts
Halftoning is a subtle yet powerful tool that enhances the clarity, legibility, and professionalism of your Revit drawings. Whether you’re emphasizing new work, de-prioritizing background content, or simply improving graphic presentations, understanding how to halftone families properly is a smart move for any BIM manager or Revit user. With the steps outlined above, you’re well-equipped to control the visibility of your models with greater nuance and precision.
Start with simple halftoning by category, then experiment with filters and templates to scale your control. The more you utilize these tools, the more efficient—and visually compelling—your projects will become.
Happy halftoning!
