Viewing Plane Lines - How to Thicken?

[ThoRig]

Community,

Is there a way to thicken the viewing plane lines in Creo 6?  The first snippet below is from ASME Y14.2, and I know that Creo can make the first two viewing plane lines, but I have not found a way to thicken them.  There is an option cutting_line_segment_thickness, but only for ends and corners, but I couldn't even get that to work.  Thanks in advance.

Line thickness is usually handled by pen table files.  These also can apply to PDF output and publishing.

I only want to thicken the viewing plane lines, not all the lines on the drawing.

These appear to be the options:
