How to renumber nodes for infinite elements? - abaqus interface

The purpose is to define specific infinite directions for elements using Abaqus as a solver. From the Abaqus manual, the infinite elements should have an origin pole and the first-second nodes pointing indicates the infinite direction. If I would like to achieve infinite directions as follows, how should I modify the node numbers in Hypermesh?

This is a 2D model and I am going to use CINPE4(4-nodes 2D elements).

I referred to this method too but I am confused by what should be the order of numbering.

    Look like you are saying about orientation

    Try enter pull-down menu Tools>Orientation Review

    change to tab 'Orientation', select elems, 

    change 'function' to 'Align N1-N2 dir'

    then select an appropriate method to do

    Thanks! That's exactly what I want.

    So according to the definition of Plan strain infinite elements, I should turn the orientation of Y to the supposed infinite direction?

    Besides, is there any advice for better aligning the direction when creating the mesh?

    I am not sure, I think it depends on your study
