AJS Ramps - what am I doing wrong?

Hi there,

I am trying to connect a spline to the AJS Ramp templates, which are named as "Grade Adjustable".

My understanding is that means you could completely remove the slope if you want to. However, I can not, for the life of me, find where you do this.

Am I missing something really obvious, or am I misunderstanding the meaning of "Grade Adjustable"?

Any help is greatly appreciated.

Grade adjustable means the whole asset can be angled to match a slope in the terrain. I don't follow when you say "remove the slope"
