With your 2 zones in place, export a hidden line isometric from your digital model into Illustrator or InDesign. This isometric view should match the isometric view from stage 03.04. Zone 1 should be identified using black fill set to 25% opacity, and Zone 2 should be identified using black fill set to 40% opacity. The fill layers should be set below any line work which occurs. Submit your file as a horizontally oriented jpeg measuring 3200x2000 pixels.

The file should be downloaded to your archlab folder by 8:30 AM Wednesday, and named as follows:
