Hi. I am trying to make a street with a median, the street should be 6" below the median and the curb. I imported the linework from an AutoCAD dwg. The median has an outer curb face and an inner face that will be a planting strip. The problem is, the linework separating the outer curb face from the street apparently isn’t connected on the street plane. As a result, when I drop the street level down, the part of the median that is its curb drops as well and leaves its outline hanging in the air (see pic). Is there a quick fix I can do to make the linework a part of the street plane so that when I drop the street, the median curb face stays intact where it is? Thanks.
