I am currently building a frame where the top members are 100x60 box section and the vertical members are 60x60 box section. The problem arises when I come to trim these members. Ideally I would like to mitre trim these members using the "Trim/Extend" tool, but this only trims at 45 degrees and, as these members are different sizes, the result is incorrect. Can someone point me in the right direction in achieving the result I'm looking for. Thank you in advance.
