In Catia V5, I have a basic assy with a part, which shows all black annotation in an MBD view. If I send the part to open in a new window, it shows white, as it should. It may be a dumb question, but what is causing this? Thanks in advance.
You probably changed the color of that part at the assembly level. Go into your assembly and from the tree Change the color of that part/instance to none. It will then match the colors of the catpart.
