With apologies to the mods in case this is in the wrong place, but I couldn't see a more appropriate location.
So, a friend has set a little problem for me, and unfortunately I'm struggling with it, so I thought I'd throw the question out to a wider audience.
What I need to do is to connect all of the similar coloured dots (circles). Have a look at the attached jpg and you should get a flavour of what I'm trying to do.
If anybody fancies having a play, I've sketched a dwg with the 6 fixed length components (blocks A - F) and the donuts are free pivot points.
The geometry as sketched is more or less right, in terms of the alignment of the two top members, but obviously the mid member doesn't connect, so it's not right.
So if anybody can come up with a solution (I'm sure that there are many possible solutions), I'll buy them a cold one. If anybody can explain to me how I can investigate alternative solutions, other than trial and error, I'll buy them a 6 pack ...
