I have a machine frame assembly where the center of mass was created. I have the center of mass symbol viewable in the assembly. I created a drawing to show the weight distribution using the center of mass. The symbol initially show up but disappears when I start dimensioning. I have the center of mass viewable in the drawing...but it disappears. Sometimes I can successfully capture the drawing with the COM symbol when printing, other times, I cannot.

Any ideas? Thanks - Frank
