I am using Revit 2013 student version. I have successfully attached a decal on one of my walls and managed to show a realistic mode of the decal in my elevation. I would like to remove the decal lines (rectangle with x inside) but I am struggling to do this.
I have done some research on the web and so far, found out that I need to select the decal lines (or cross), right click and choose Override Graphics in View > By Element, and check Transparent. The problem is, my system does not display the option for Transparent; I am only given the boxes for Visible and Half-tone.
