How to change the print color in plan of a 3d sink downloaded from Kohler

[L.S.]

I downloaded a 3d sink from the manufacturer (Kohler). In 3d, when I hide contour lines, it looks fine, but in plan the contour lines are purple, and unfortunately when I print to PDF they stay purple. Does anyone know how I can make them print to pdf in black? When I open the family it won't let me modify it (can't even select the object).

Post the family.

How about a Kohler Tub instead?

Your family might have been created in AutoCAD.  If so, change these in Object Styles, under Imported Objects.

This is the link to the RFA file. https://www.us.kohler.com/us/Whitehaven-Self-Trimming-Smart-Divide-35-11-16-x-21-9-16-x-9-5-8-under-...

Thank you Tim, but I looked in imported objects and it's not there.

 So, are you unable to change these line colors?
