[Woodcarver] Pyramid Thanks

[WorkingInWood]

Your welcome Jean.  I solid modelled a pyramid in AutoCad and extracted the 
dimensions I gave you from the drawings so they should be very close.  I 
can't totally guanantee them since I haven't actually built the pyramid.  I 
don't believe you can build a pyramid using triangles with 60 degree angles 
(all the same length sides).  Try it using cardboard pieces (cereal box 
cardboard works well).  Good luck.

Larry
