Profile with 2 terrain

Hi

I have two terrain in my drawing, on future terrain and one existing. I have insert a "hole" feature line to remove existing from inside this bounduary in my plan. In my profile I jusrt want existing to shot up to to where future terrain begins. But it is visable all te way, no matter what feature type I chose..."Void, Drape Void or "Hole"

I am using Powercivil SS4 for Denmark

regards

Sigfus
