Angled Beams on Gable Porch

[QD5NS-4WAEZ-YRB7]

I am attempting to complete a gable porch with pillars and angular beams within the gable. I have been able to complete all of the beams without a problem but have hit a snag with the two remaining angled ones shown as polylines in the below image.

I cannot find a way to rotate the object I created. I created the pillars using a slab and adjusting the dimensions. I am thinking it is not letting me rotate because it is concrete? Not sure... I have spent a couple hours on this and search the forums and I cannot find it.. 

 

I am using Home Designer Pro 2021.
