    What do you mean 'disorded' ?

    i wanted to keep thetra mesh the same, only mid nodes added, but after change to 2nd order. midnodes are not in line between main nodes.

    Hi

    I think you switch the option to 'midnode projected to surf' so they are distored

    change to 1st, then change again to 2nd with 'mid node exactly mid point'
