Thank you guys for the information, very informative. It appears there is no simple way to convert the NX human model to a solid model.
The solid model of a human in that thread is pretty much exactly what I need except in a bicycle riding position.
Is it possible to subtract the human model built into NX from another part, such as a box? I am trying to use the subtract command but I am unable to select the human model.
I am trying to do this in order to perform a fluid flow analysis. Any help would be appreciated.
