Lesson V - icosaedron construction

Today I have created icosaedron

1. The bottom and top of this object is created with pentagon base and 5 triangles.

2. Using 3DARRAY command I have created other faces.

3. 3DMIRROR gives me base of the icosaedron.

4. Rotate one base of 36 degrees.

5. Using triangle and 3DARRAY command I create other faces.

6. I copy 5 faces and use 3DMIRROR, ALIGN and MOVE to complete object.
