Drafting pyramid shapes and working on rounded corners with slanted sides. Began by building a 30x30m block. Pushed the base up 4 m. Offset the next step by 2m from the sides. Set a point 10 m from the corner of the base layer. Cut the corners at 10m using the Arc tool. Relied on inferences to set the Arc poitns on the other corners. Repeat this process for the four layers. To get slightly slanted edges on the sides I used the followme tool. Still fumbling with ramps and stairs. Opted for a ramp on this one.
