And :) of course, after a common coordinate system is defined, directly Cutting and Pasting the Mathematica 3-D patch image directly into Ansys screen... by right click or GUI.. that is my final Graphics Import (Important) dream ! Anyhow Mathematica can now itself identify tangents, normals and binormals, useful for defining of load application along correct directions, to arrest not required DOFs etc. Narasimham
