I've just about finished modelling the lamp (http://www.robertschofieldaudio.co.uk/ebay/anglepoise3.max) using Max 6, but I've really no idea about rigging it so that all the joints work correctly. The lower legs are a parallelogram style thing, supported at the bottom by three springs. Two of these springs are missing from the model at this stage.
I just need the 'legs' of the thing to move properly when I move the nuts that support the head of the lamp around. The head can also rotate separately around a pivot at these nuts. If anyone can offer advice on how to rig this thing up, or point me in the direction of a tutorial which borders on this, I'd really appreciate it.... I'm so out of my depth here!
I'd recommend doing a tutorial on linking and look at controllers (not done the tuts with max for many a year but there should be some on this) then applying it to this case. You need to work out how it'll move and where each piece should pivot, move its pivot point (use align tool) etc etc.
BTW, I really would recommend not using groups at all, especially groups within groups within groups! When you come to animate, things can go screwy. Also, if you have a nut and bolt that will never move etc, why group? Just attach them all together....it's good scene management - when you get to complex scenes it saves having millions of nested objects.
