This is a second tutorial after the first basic one to make a sphere construction using Buckminster Fuller. The downloadable pdf file contains demonstration videos. Please check this before you start this tutorial: http://www.slideshare.net/yudhidayak/how-to-make-the-organic-sphere-using-buckminster-fullers-ball-principle

1. How to make the spokes using Buckminster Fuller’s ball
Step 1 – You have 1 pentagon surrounding by 5 hexagon
Step 2 – Create curves to build a spoke
Step 3 – Create a solid spoke

2. Step 4 – Copy rotate 2 more spokes based on hexagon centre.

Step 5 – Copy rotate 4 more set of
spokes based on pentagon centre.

You can use these files to evaluate your creation:
-sphere-basic-lpdu-model-01-
spoke_curve_construction-result.igs Note:
-sphere-basic-lpdu-model-03-make_solid_spoke-
result.igs The spokes can be anything, then copy-rotate 5
-sphere-basic-lpdu-model-04- spokes for pentagon and 3 spokes for hexagon.
copy_rotate_3_spokes_on_hexagon-result.igs
-sphere-basic-lpdu-model-05- Or you can configure with others way (e.g. 6
copy_rotate_5of3spokes_on_pentagon-result.igs
spokes for hexagon)
