Suppose I give input as global x-axis direction, I need the first node in same direction for the FE

    1. Ignore nodes that have globalx < 0 use *createmark

    2. With nodes have globalx > 0, get closest node to (-1000000, 0, 0) use hm_getclosestnode

    @tinh get closest nodes are not selecting the right node. This is because I have bracket in front but at bottom position. So, it selects closest node in front but misses the bracket as its away down. I need the node which touches first like a plane crossing

    So, Ignore nodes which are far from X axis

    Use createmark with option 'on plane' or 'by cylinder'
