Working with Linked CAD Files in Revit When printing our sheets we noticed the linked in CAD Files were printing a lot lighter than the work done in Revit. There are two ways to fix this, one is to create a View Template and going into the V/G overrides and change the line weights in the Imported Sheets category. However, we found an issue with this solution, the View template kept resetting itself for some reason. So we found another solution using Object Styles, this is located in your Manage tab, go to Imported Objects and change the line weights under the imported CAD Link.
