This is based on a picture of Chichen Itza.
I did not use loop tools to create these ramps. Not knowing the next lesson challenge would have me creating a ramp. What I did was I made 1 step and lined it up in roughly the middle using orthographic view. Then I extruded 1 edge along the z axis using orthographic view facing the front of the ramp to line it up with the top level. Then, switching to a side orthographic view, I grabbed that edge and moved it along the Y axis until it touched the top edge. From there I extruded it inward 2 units and replaced the face. Then I made sure the normals were facing outwardly and removed any doubles I might have created. Then, since my pyramid is sitting squarely over the center, I hit shift c and then changed my pivot point 3d widget to the center and rotated copies of the ramp around the model. The only thing I did not necessarily achieve was making sure the ramp was directly in the middle, but I can’t tell if the rotation of the copies would show this or not. Using a loop cut one can create a center line of reference to better use the method that I did.
I hope this is useful information to you.
