    Hi
    If you want to make arc contour in Femmview, the simplest way is to
    make that contour as an arc in FEMM (before solving the problem).
    After that, if you try to make contour in FEMMVIEW (as a straight
    line) i.e. you choose the endpoints of arc (by left button of
    mouse), FEMMVIEW recognises the arc and highlight the arc.

    In LUA scripting, if you want use that funcionality, you have to make
    contour by "selectpoint(x,y)" instead of "addcontour(x,y)", which
    makes all the time just straight contour.
