hey, that worked. thanks. didn't know there is limitations to the size.

Hi,

when i intersect a plane to the cone, part of the cone's face got deleted automatically. why is that happening? they are fine as two, but when i selected the two and "intersect face with model", part of the cone gets deleted.
i am trying to cut out part of the cone parallel to the blue axis. any advise is appreciated. thanks.

John
