Display Material Orientations for CQUADX4 Elements in NX 8 Nastran

[FreeJBird]

Hi All,
Please help me to display the material orientations of antisymmetric CQUADX4 elements. I set the material orientation angle to 45 deg in the "Edit Mesh Associated Data..." dialog box. I then tried to plot the material orientations by click check->material orientations. However, I received the following error:

These marked elements were skipped due to invalid orientations:
------------------------------------------------------------
570
571
572
... (elements 573 to 698 are listed here)
699 (last element in mesh)

Please tell me how to correctly plot the material orientation.

Thank You!

Hello!,
Please note axisymmetric elements CTRAX3, CQUADX4, CTRAX6, and CQUADX8 of NX NASTRAN should be defined in the X-Z basic coordinate system, all grids and loads must lie in the X-Z plane of the basic coordinate system, where the Z axis of the basic coordinate system is the axis of symmetry and the X axis of the basic coordinate system is the radial direction. I tell you this because you mentioned on yur post "antisymmetric CQUADX4", and not any "antisymmetric" element exist in NX NASTRAN, antisymmetric refers to boundary conditions not element type.

If you do things correctly then plotting of material angle will success, here you are proof of this:

Best regards,
Blas.

PD
Of course, when defining the NX NASTRAN SOLVER ENVIRONMENT in the study make sure to select "ZX Plane" for "2D Solid Option" question, this is "NONE" by default, OK?

Hello!
Thank you for the detailed reply. You are correct that I meant to type axisymmetric and not antisymmetric. However, I am still getting the same error as before. Can you post the Mesh Information? My Mesh information is:
