How do I delete an imported CAD file from My revit Project

[Stephm419]

I am working in a Revit 2015 project.

When I went to the Visibility Graphics dialogue box under Imports, there are 15 CAD files.

How do I get rid of them?

You guys can try: go to Manage > Object Styles > Imported Objects then delete the subcategories. It works for me 😄

In order to remove I used CTRL Z since it had not been saved yet.

Hello Guys
Just an update 2023 to the matter mentioned in the question above,

there is now an add-in called pyRevit, it has many usefil tools to apply on your Revit file, but our main concern today is the one that called Links > then choose List DWGs - it will open a window have all the DWG imports categories with a search in a view option or USE THEIR ID number and search for them using search by ID method in Revit, once you select it- press delete and voila - you will get a clean file from the DWG stray parts everywhere. 

it will ask you when pressing List DWGs to select from the view or the ones in the model
select what you seek, most probably will the Model to have all of them at once

And then you will have the results listed with the information as attached below:

Thank you for bringing the matter up @Stephm419

If it doesn't matter that anything gets deleted. You can go into Manage tab > Object Styles > imported categories > and delete all the line types underneath your imported categories. Sadly I do not know how or if it is possible to delete the categories themselves - if you have exploded those CAD imports...
