Flicker on thin volumes |
Turn on two-sided lighting. Thin volumes such as I- beams may have a special type of coincident surface bleed through caused by the back side of the I-beam behaving as a coincident surface with the front side of the I-beam at some view angles. |

Coincident surface shading issues |
Coincident surface bleed through occurs when two surfaces are defined at the same coordinates. This problem is especially obvious when two planes are coincident on the ground, floors or walls of a plant. To work around the coincident surface flicker problem: 1. Turn off the level of all but one of the coincident planes in the offending files. 2. Assign the same material and /or color to all elements coincident at one place. This will help disguise the bleed through problem. |

Flicker caused by element center lines and line strings |
During motion the lines may show up at some view angles, causing some flickering to occur. We recommend not keeping the lines and line strings when creating the project database. |

Improve curvature of many circular graphic elements |
Increase the stroking tolerance from the minimum setting of 16 to give a smoother curve on round surfaces such as pipes, elbows, valves, and so on. Increasing the stroking tolerance to between 30 and 50 is usually adequate to give smoothly stroked curves on basic circular elements. Increasing this setting may reduce performance but will improve visual quality. |

Lighten or darken the display |
Adjust the ambient and brightness settings. If you have the Photo-Realism module, add lights to the model. |

OpenGL lights too bright in shaded modes |
Reduce the brightness setting on the View > Settings > View > Lighting dialog box. Reducing the brightness may help most with directional and positional lights. |
