LCS & Ground Body

Can anyone give a definition of these ?



PTC help is kind of sparse, they tend to overlook the most basic items...



Also, how do you set the LCS for a body ?

When I set the LCS for an animation it doesn't remain in the same location so when I do a rotation everything wanders.



Any suggestions as to how to fix ???

Don't think LCS is located at the centroid of a part - or assembly for that matter.



From what I can tell these can only be located at a csys. but I'm not clear on this nor is PTC documentation.



I have an assembly that consists of only one part which has only one csys and the assembly has one csys itself. This means two LCSs.



When I use the part LCS to rotate around everything works as expected. When I rotate about the assembly LCS this LCS wanders.



The only reliable LCS is the part LCS but unfortunately any translation or rotation moves this LCS too.



I apologize for asking such basic questions. Have you actually used animation ???
