Revit Snippet: Batch-Hide roof & floor interior mesh edges
If you use Revit regularly, you have probably seen how distracting interior floor and roof edges can be. These tangled lines often show up across multiple views, cluttering your drawings and pulling attention away from more important elements.
While these folding lines are helpful for visualizing the 3D shape of a floor or roof, they often get in the way when you are preparing clean, readable presentation drawings.

The Problem with Manual Fixes
The typical way to hide these lines is by going to the Visibility and Graphics settings, expanding the Floors or Roofs category, and turning off Folding Lines. This method works but it is painfully slow when you need to apply it across many views.
Some people rely on view templates to control visibility settings. That can help if your views all share the same template. But in most real-world Revit models, views are varied and inconsistent. This means you are either stuck making manual changes or constantly tweaking multiple templates.
A Faster Way Using Dynamo and Python
In my latest YouTube video, I walk through how to solve this problem with a Dynamo script. This script automatically turns off interior edges for all floors and roofs across all valid views in your model. You can do it with just one click.
The script checks each view in the model and applies the visibility change only where it makes sense. It skips over views that are locked to templates or that cannot display floors and roofs in the first place. The result is a fast and clean solution that leaves you with clearer views and more time to focus on design.
You can download the ready-to-use script from the video description. If you prefer to learn and code it yourself, the video also includes a step-by-step tutorial explaining how to write the Python script inside Dynamo.

What You Will Learn in the Tutorial
This tutorial explains how to use Python in Dynamo to automate repetitive visibility tasks in Revit. You will learn how to
- Identify and collect all views in your model
- Safely skip over views tied to templates or with no visibility control
- Turn off specific categories like floor and roof folding lines
- Create lists to track which views were successfully modified
- Run your changes in a clean and safe transaction
