When i choose miter joint in the joints tool, and move my cursor on a pipe(which was made using the profiles tool) it doesnt get highlighted and i cant select it so i cant make a miter joint. Corner joints are also not working, but t-joints, normal cuts, cutout, trim, replace are working. I tried restarting creo, restarting the computer, try to make miter joints(with pipes) in a new assembly, the problem remained. I tried with other profiles like U beams and i could perform a miter joint succesfully.

Creo 3.0 M100

Can somebody help me fixing this problem?
