Add the ability to trim/adjust toolpaths (such as ones generated with Trace) so that they do not collide with the part or the fixture. Other CAM programs either allow you to control the roll off angle of the tool or automatically generate "trimmed" toolpaths which check for collisions between either the tool or holder and the part or fixture. Right now the only way to do this in fusion is no manually generate a sketch which is very "clunky".
