Technic Geometry Help

[aminnich]

I have been trying to make various different shapes using any kind of technic parts I have.  

I made a circle, no problem. 

I tried making a hexagon, failed

I tried making a triangular prism, failed.  

I am trying to make these as compact as possible with some strength to them, I do not want them just to be able to be pulled apart. 

If anyone has thoughts on how to make these shapes and other shapes successfully, show them down below. I am curious what you guys come up with.  

PS, I was building them in LDD so that I would know if the placement of the pieces was considered "legal" or not.

Several different hexagons here http://www.brickshelf.com/cgi-bin/gallery.cgi?f=193780

You could probably create these shapes using part 57585 and some axle joiners, or it's counterpart 10288. You would just end up with some extra axles protruding at the corners.

Can we see the attempts you have made? The parts described by Captainowie will help with creating shapes, such as the triangular prism. However. If you want to make the edges rather than a skeleton (over which the convex hull is the desired shape), then you might need other construction techniques.
