I am trying to set up a rig with certain relationships between the bones, and having real problems working it out. Any assistance appreciated!
I am (still) using 2.49b.
I have attached a .blend file to illustrate the concept (I am aware that the model itself is not great). There is no rig in this .blend, because all of my attempts so far have been less than successful.
What I would like to acheive is a rig where the front plate would be flat against the larger cube, with the arms inside the cube. Moving a bone outward to open the plate so that it opens in a way that it is hinged on top (to result in a position like that in the .blend file) would also cause the Upper arms attached to it to slide along the groove in the Lower arms, until the pin in those grooves that is attached to the Upper arms reaches the end of the groove in the lower arms, at which point the Lower arms also slide out (again resulting in a position like that given in the .blend file).
I hope I haven’t made it sound more complicated than it is: hopefully you can open the .blend file and see what I am talking about.
Again, if anyone has the time and inclination to give me any clues about how to rig this, I will be forever grateful. Thanks in advance.
