Patrick,
The flashing is caused by a 3D model that has issues. In your model, some flashing is caused by model "faces" being inverted and/or model pieces overlapping. Inverted faces should be selected and inverted again or deleted and recreated.
Within the "fuse" object it looks like you started with a "pipe" object as the basic primitive instead of starting with the "cylinder". Now you have faces covered up by faces. This is not good. It might be easier to recreate the "fuse" based on all the changes needed.
However, there is a way to get rid of them. Click off the [Ln] and [Fc] buttons until you only have a wireframe. Then under edit options, click off the [Ln] and [Fc] buttons as we will only want to select points. Select points that are the inside of the pipe and delete them. That should help a lot. If you have areas that open up on your model, select two close points and <Join> them together under menu <Selected> <Join> or Ctrl-J.
If you want to see what issues your model might have, select each object and then go through the <Object> menu and <Join Closed Vertices> at "0" to make any two points that are together become one point, if the model looks worse, Ctrl-Z to undo, <Align Faces>, if zero your model is OK, if not zero, Ctrl-Z to undo and fix the problems, same thing with <Delete Overlapped Faces> and <Unify Faces>.
Once your model passes these basic integrity checks, you will have a better 3D model that is more efficient with fewer polygons and fewer issues.
Thanks to Treehugger for helping me understand some basic issues with my models. Pass it on....
