I need some help here.
I have a corridor and are building my sections from the middle and out and i need to do a subgrade in my sideslope, look at the picture.
I need to do a subgrade 70cm perpendicular from node 6 at a given elevation and from the surface created between node 4 and 5 and the slope between those 2 are changing.
Is this possible? I cant figure this out.
