Hi @anass2010,
Unless this element came from Forma (it doesn't appear so), you may want to post this question in the Revit forum.
Thanks!

I Can not change or rotate the elements as i clearify in pic attached
Hoping to help me
if i understand, you need to change the direction or rotate the structural beam and column, the normal with chose direction of your drawing make a mirror element for u, but for make the rotate you need to change the Cross-Section Rotation and this make a great problem , he rotate the direction of element and axes too.
for this problem i make the new family with extra variable that have no problem to change the direction.
i hope the picture help more.
