Mix 2D- and 3D sketches to create this platonic body.

1. Step 1: 1st polygon and 1st 3D sketch

   

   First, draw a hexagon.

   start a 3d sketch by projecting two sides. At the vertex start a line and dimension the angles.

2. Step 2: create work planes and continue sketching

   

   with edges define the appropriate work planes and continue sketching one pentagon and another hexagon.

3. Step 3: circular pattern

   
   

   

   make a pattern and with two edges, create the work plane for the next hexagon. continue with one more hexagon and a pentagon, pattern this group three times.

   

4. Step 4: work point, plane and mirror

   

   Create a workpoint on edge, stitch all surfaces to one single surface body.

   

   define plane with workpoint and top plane, then mirror

5. Step 5: move body

   tt

   

   use "move body" and rotate 60 degrees. stitch all.
