How to check free 1D's in RBE2 or RBE3 element's rigid loops?

Hi Everyone,
Is anybody knows ,
1.How to check free 1D's elements (In RBE2 or RBE3 elements rigid loops,) in NX Nastran Quality Checks? ,
2.How can one review the RBE2/RBE3 elements' dependent/independent nodes?
3.2D shell mesh is looking one side transparent, Why? 2D Element's Normal have to reversed, to view it . How can we see a Shell Mesh from both sides ( I don't want to view it one side transparent )?
What should be done for better mesh/element visibility?

Thanks in advance...

Hello!,
I understand you are using NX AdvSim as pre-processor, not FEMAP, right?.
1.- In NX AdvSim is difficult you have any free RBE2/RBE3 elements, NX control everything if you mesh in NX. Only if you import the FE model could be the case. In any case, in the FEM environment look for free nodes.
2.- If you have any "double" dependence then NX NASTRAN will give you error when solving. Double dependencies occur when two elements share a dependent node. If your model contains double-dependencies, the solver may not be able to correctly resolve the degrees of freedom in your model.
3.- Set OFF the BACKFACE CULLING
