frames tool

How to mirror a frame part with features and keep the cut list with lengths? When I mirror a frame part and make a cut list I get the error "Failed to find frame start and end faces.". The frame shows up on the cut list but not with the correct lengths. Is it possible to mirror a frame part and keep the correct cut list?…

I have a set of extrusions that are absolutely always used in pairs with brackets to keep hem assembled. They are in fact assembled before mitering ends. When tried using a sketch with 2 profiles included the result is failure in the frame feature. No error messages, just nothing appears. Is there a way to accomplish this…
