how to know inner and outer loop??
hi all,
i have odbrface, and from this face i am getting odbrloop.
but i couldn't find weather loop is inner or outer in case of multiple loops.
i am attaching dwg file which has one face and 4 loops.
please help me to decide weather those loops are inner or outer.
thanks for your time..

hi
there is no method like getlooptype. you should calculate it yourself.
hi,
could you please give me a hint how to do that??
thanks..
hi
you should calculate 2d loops from 3d loops. 2d loops are loops in uv plane of surface and check loop orientation cw or ccw. this is not trivial task.
