Gutter Material Changes to Siding??

This looks like what is called z fighting. Basically it boils down to how the algorithm for rendering 3D works. You can think of it as taking a fixed number of very thin slices of the model that are parallel to the plane of the computer screen and then layering them on top of each other. This is done 1 pixel at a time so if two items are very close to each other or share the same plane you will get somewhat random results when the computer computes which item is in front.

In the case of things being very close to each other you can help the situation by moving the front clipping plane of the camera further away from the camera location. This can be set in the camera properties.

In the case of two items occupying the same plane what you can do depends on how it was created. If it was created by Chief automatically you may not have the control to change this. But if it was created by you, for example if you pushed a polyline solid into a wall where the outer surface was exactly at the outer wall surface then you can deal with the problem by either moving the solid around or perhaps creating an opening for it.

I hope that all makes sense. You can always contact our support team and they can help you out.
