High and medium retain the virtual MPN in its reviewed location. All four exclude the footprint outlines, pad labels and silkscreen used by the separate annotated wiki hero; the EDA board supplies those layers.++Cached PNG/WebP previews show each level without starting another 3D viewer. Choose **Turn on 3D preview** to inspect zoom-driven detail changes. Closing or hiding that preview releases its models and viewer resources.
