No. I just want to cheat, designing only one part when an actuator has at least two. > At least, the only things I can think of off-hand that actually changed size > were the inflatable engine intake edges on very early Harriers. > > It would be better to try to figure out how the mechanism you're trying to > animate actually works, which for fixed size parts is going to consist of > translations and rotations, and try to duplicate that.

Look at the main gear of the A320 when retracting to see what I mean. There is no translation yet but combining rotations by hand and calculator is already a pain. > Trying to mimic the mechanism will also make it possible to simulate failures > more accurately - not necessarily the most obvious consideration but it's a > strong 'plus' feature. -Fred _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
