How to Hide Lines in a Linked Revit Model

To hide lines in a linked Revit model, particularly annotation elements like Grids, you typically use the Visibility/Graphic Overrides settings. This allows you to control the display of categories within the linked file from your host project.

The most common way to hide specific types of lines or elements from a linked model is through the Visibility/Graphic Overrides dialog box. This method provides granular control over the visibility of categories (like Grids, Walls, Doors, etc.) within the linked file.

Here's how you can hide elements, using the provided reference steps for hiding Grids as an example:

Using Visibility/Graphic Overrides (VV or VG)

This is the standard approach for controlling the display of linked models.

1. Open the Visibility/Graphic Overrides dialog box by typing VV or VG on your keyboard, or by navigating to the View tab > Graphics panel > Visibility/Graphics.
2. Go to the Revit Links tab.
3. Find the linked model you want to modify and click the button in the Display Settings column (it will likely say "By Host View" or "Custom").
4. In the RVT Link Display Settings dialog box, ensure the Basics tab is active.
5. Under Display Settings, select Custom. This allows you to override the linked model's display settings.
6. Now, navigate to the Annotation Categories tab.
7. Under Annotation categories, select Custom.
8. Scroll down to find Grids.
9. Clear the Visibility check box for Grids. This will hide all Grid lines originating from the linked model in this view.
10. Click OK on the RVT Link Display Settings dialog box, and then OK on the main Visibility/Graphic Overrides dialog box.

Reference Steps Included:

Based on the provided reference:

1. On the Basics tab (within RVT Link Display Settings), click Custom.
2. On the Annotation Categories tab, for Annotation categories, select Custom, and then clear the Visibility check box for Grids.

This method effectively hides the Grid lines from the linked model in the current view.

Hiding Other Types of Lines or Elements

The same Visibility/Graphic Overrides method can be used to hide other "lines" which are part of model or annotation categories in the linked file:

• Model Lines/Detail Lines: Go to the Model Categories or Annotation Categories tab within the RVT Link Display Settings (Custom), find "Lines" or "Detail Items", and clear their visibility.
• Edges of Elements: Edges are part of the geometry of model elements. To hide the edges of walls, for example, you would go to the Model Categories tab, find "Walls", and hide the entire category or adjust its line style/transparency.
• Levels: Similar to Grids, Levels are typically annotation categories. Go to the Annotation Categories tab, find "Levels", and clear the visibility checkbox.

By utilizing the RVT Link Display Settings within the Visibility/Graphic Overrides, you gain precise control over which categories from the linked model are visible in your host view.

Other Potential Methods (Briefly Mentioned)

While V/G Overrides is the primary method based on the reference, other techniques exist for more complex scenarios:

• Worksets: If the linked model is organized by worksets, you might be able to control visibility based on workset status (though this requires coordination with the linked model).
• Filters: You can create filters in your host project that apply specifically to elements from linked models based on their parameters.

In summary, controlling the visibility of lines and other elements in a linked Revit model is best achieved through the Visibility/Graphic Overrides dialog, specifically by setting the linked model's display to Custom and adjusting the visibility of individual categories like Grids.
