Finite Element Modelling using NX4

Dear All,

I am trying to do a structural analysis of a 3d truss. Using NX3 in the past I was able to model the truss memebers as 1D elements and apply loads and boundary conditions. I have since upgraded to NX4 and find that I am unable to do analysis of 1D Meshes.

If you are able to tell me how to apply loads and boundary conditions using NX 4 to specific points (i.e. line junctions - not to faces or surfaces) that would be very helpful

Thank you
Droo
