If you're working with Revit and want to delete cameras from the 3D view, it's actually quite simple. Here's how you can do it in just a few easy steps.

1. Open your Revit project and navigate to the 3D view where the cameras are located.

2. Once you're in the 3D view, look for the cameras that you want to delete. They will usually be labeled as camera symbols.

3. To delete a camera, simply select it by clicking on it with your cursor. You should see the camera highlighted with a bounding box or selection handles.

4. With the camera selected, press the 'Delete' key on your keyboard or right-click on the camera and choose the 'Delete' option from the context menu.

5. Confirm the deletion if prompted, and the camera will be removed from the 3D view.

That's all there is to it! Now you've successfully deleted the cameras from the 3D view in Revit.

It's important to note that deleting a camera from the 3D view does not remove the actual camera from the project. The camera will still exist in the project, but it will no longer be visible in the 3D view. If you want to completely remove the camera from the project, you will need to do so from the project browser or the 3D camera views.

Deleting cameras from the 3D view can help declutter your workspace and make it easier to work with your model. It can also improve performance by reducing the amount of geometry that needs to be processed and displayed in the 3D view.

So next time you need to clean up your 3D view in Revit, remember these simple steps for deleting cameras. It's a quick and easy way to tidy up your workspace and focus on the important elements of your design.
