When I right click in the feature tree area and Document Properties comes up, and I go to Colors, the Model/Feature colors window comes up and When I try to edit the different categories...shading, hidden,bend, boss, cavity, etc, all to a light metalic grey, the only color that comes up after I extrude a rectangle for example is a very dark charcoal grey, and not suitable for visibility at all. Please tell me where I am going astray with the configuration. My eyesite prefers that my models be a light grey, rather than darker colors. Thank you, Uma
