I know that I have a terrain polygon on my plan because I can see and manipulate it in 3D view, however it is not visible when I view the plan. I don't see it on any level, therefore, I can't create terrain data lines or create a terrain. If I start a new plan and create a terrain perimeter, it is visible in that new plan. I am not aware that there is any way to turn visibility on or off. Anybody got any ideas?
I am using HomeDesigner Pro 2021 on a Mac Mini running OS 11.6.1
