Model under process

The model what I showed before is for an other student. We have to swap our's to a classmate so I got mine from somebody else too. This is that model what I have to create in Rhino. First we made photos about it and after that we inserted into Rhino to help us how the lines go.

Here are some renders about the half of the model what I have to continue on class. I have created it by repeating the same triangle just I have to rotate it in 3D as you can see on the model photos. The only difficulty is that at the other half, what I haven't made yet this type of triangle will become half size so it means more shapes, more rotations, more details. The point, lines, edges which ones stand on the ground helps me to make the right shape.
