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.
