Component Color

When the layer for the Model was created, the color override option was not selected. When the color box of the layer is shown in non-override mode, shown below, the color of the component can be changed infinitely in the editor. When a color is selected, this represents an override and only the selected color will be used for this part.

Layer color override off for layer Model; on for Sketch.

When the layer color override is off, shown above for layer Model, the component color drawn on that layer can be changed at any time. This is useful when there are multiple components or sub-assemblies as it provides an easy contrast between parts.

Position the cursor over either part, then right click and select Color. Select different colors for the components, similar to the illustration below.
