Rotating Ref Planes in Multiple Axes

[Limbatus]

Hello,
I am trying to accurately rotate reference planes in multiple axes, but struggling. When I rotate the Plane in the South Elevation, it disappears from my East and West Elevations. How do I accomplish this in the Project Modeling Environment?

Care to elaborate waht your really after?

If a reference plane is not perpendicular to a view, it will not be visible.

I have a steep site with a lot of topography. I want the top edge of my retaining walls to mimic the slope of the earth below, so that if there is a set of walls in a series, they all have a consistent trend for a top / cut constraint.

If your comfortable creating a surface in the conceptual massing environment...

Marcello's example is a parking lot, but you could just as easily create a retaining wall with the aid of entourage families
