This is my first time modeling a corridor using instructions. When I start my corridor the concrete median seen below has always been to the right of the alignment (magenta line). When the typical section changes the alignment is located inside the concrete median. If I insert an Offset/Slope instruction, the concrete median attaches to the alignment. In this case it is 6" lower than where it should be. Any idea how to get around this so the concrete median will model 6" higher?
