In ArcScene you can change the drawing priority of each of the layers being displayed, so the more important layers will render on top of the less important layers. Using the 3D Effects toolbar you can change this property quickly.
- On the 3D Effects toolbar, click the Layer drop-down arrow and choose the layer you want to change the draw order for.
- Click the Change Depth Priority button and move the slider to a value.
In the numeric scale for depth priority, 1 is the highest and 10 is the lowest. If you want to decrease priority, choose a higher number.
