The joist size is set to 125mm which I would say is not really to any code- and can't be changed

Using Home Designer Architectural 2015 They're disabled in the screenshot you are showing. But I'm surprised that they are missing from the 3D Frameview

Good afternoon I just found out that I can't edit the height of the floor joists / ceiling structure Should I be able to see the Rim Joists in 3D Framing view or is this deliberately invisible in Architectural 2015 Thanks
