I am sure there is a pretty simple answer to this one. I am using the defalt styles that came with C3D 2011. How can I change the colors of the corridor "frequency" lines. The lines I am referring to are those that are from the last sub assembly to the daylight line. This is prior to making any section views or surfaces. The colors have to be determined somewhere within the corridor styles I think, but I can't find where. Can somebody help?
