Human Modeling - How to "fit" a person on a bike

[jonashaug]

Hey guys, I'm quite new to human modeling in NX. I've made a model of a bike and wish to put a woman on it and then make a motion simulation and animation.

In the bike-assembly I can't seem to move the woman where I want after adding her. She's stuck with her left toe in the origo which is in front of the bike. I can move the arms etc.

Is there a way to use mating conditions to get the foot to stick to a pedal and the ass to a seat? and thus making the persons legs move when i spin the pedals...

Any ideas on how i can get this done?

Thanks,
Jonas

OK, to start with, you have to be in the Human Modeling application before you can actually move any of the body parts since these are not simple mating conditions but in fact each 'joint' in the body has designed in limitations as to how far it can articulate based on real human anatomy, thus preventing you from actually putting your subject's elbow in his/her ear. What you will need to do first is double click on the manikin which will bing up the 'Edit Human' toolbar. Once this tool bar is open all you need to do is simply select each joint which should then display a 'handle' which you can then use to move that body part about it's joint(s), such as an arm or a leg or a finger or whatever. Remember to pick 'above' (or 'ahead') of the part you wish to move, such as selecting the forearm to move the wrist or the wrist to move the thumb, and so on. Note that in the case of moving the hand you might be better served by using one of the preprogrammed hand shapes accessed by selecting the 'Hand Shape Library' icon. Or you can even start out using one of the whole body setups found under the 'Human Posture Library' icon (perhaps one of the setting positions will be a place to start).

Anyway, give that a try.
