This is a Curved Staired Pyramid, made of 9 stair stages. It would be ideal as a decoration for outdoors ancient or modern and why not futuristic scenes. It was made with Blender and rendered with Workbench, I also proposed other formats than .blend as : .abc, .dae, .usdc, .fbx, .glb, .obj, .ply, .stl and .x3d.
There are no material or texture applied to the mesh, its purpose is more likely to be a base mesh to begin a work so you can save some time.
I first made small one which is the original shape and then made 2 other taller version with a proportional scale tool, a medium one which just a little bit higher than the original and the taller at the right which looks like some ancient building shape. You can easily modify it by yourself to get other proportions.
Each pyramid is 54 polygons and 72 vertices.
I am at your disposal if you have any question or if you would like a custom model.
Thanks !
