Hello all, I'm having an issue when connecting a terrain curb or sidewalk to a terrain wall. When I connect the wall, they seem to want to attach to the top of the terrain wall causing a spike or peak in the terrain. I don't have any elevation changes on my plan - it just a flat property. Any help would be great. I tried to upload my plan but it's larger than allotted size for this forum. Thanks! E Home Designer Architectural 2022
