@solver
Thank you very much! I changed what you showed in the video and it's working as it should. Thanks again for taking the time to help me solve my issue.
I'm not sure if I have something set wrong in my settings.
I opened up another plan and it worked on that one so I copied and pasted it to the plan I'm working on.
After drawing in a floor truss with the truss tool, it’s definitely not a floor truss when looking at it in the 3D view.? Is this not available in HomeDesigner Pro software.?
