Using Mutual trim option not able to select the required knitted surface. And also solidworks display "One or more surfaces cannot be trimmed into multiple pieces".
Hello Anand,.. if you look closely, it's most likely the trimming surface(s) are running onto a singular vertex/point or edge/coincident so it faults or the face(s) are not enough within the the boundary of area for the trim to resolve.. so, if you just move or extend, it can help with resolving.
Otherwise, if you can post/attach the file (or just the surfaces involved, export them as parasolid).. we can look at it.
