There is not enough information in what you submitted to know what the problem is... And the attached pdf only shows a warning dialog... Please give us a step-by-step procedure explaining how we can reproduce your problem, and if possible a screenshot showing the problem happening, thanks! |

This is a know phenomenon in 3d rendering called z-fighting and actually not a bug. See: https://en.wikipedia.org/wiki/Z-fighting If a shaded and a wireframe display of the _same_ model is done this can be fixed by the use of a polygon offset. But with two independent objects like in this case it's nearly impossible to do something against it. |

Understood - thank you - sorry for the hassle. I am returning to using CAD after teaching it to high school kids back in the 80's and 90's - things have changed just a little. Cheers. Case closed! :-) |
