I could not figure out a good way to do this in DD3 last night. I have a large cave which has a central pillar that stands about 20 ft above the ground. A narrow ledge circles around the pillar climbing to the top. I could not find a good way using sheet effects to create that effect. I could always just make something in Photoshop and import it as a symbol. But I'm really trying to learn more of the ins and outs of CC3, DD3 and CD3. Any advice?
