Display Z-Features without 3d-Surface

Question

Hello,

I have a kind of comprehension problem in the 3D scene-function of ArcGISPro (3.5). For 20 years I have only worked in ArcMAp and ArcScene - now I am changing into AGP since over a year and am missing or misunderstanding a few functions in AGP.
The following: I created a 3D line (Z-feature) that was always immediately displayed in 3D in ArcScene. I could rotate and pan these Z-line features and view them from all sides. In AGP, although this feature has Z values, I always have to place it on a 3D surface - but I don't even have this surface yet. On the contrary - the Z-line feature is part of the surface I want to create. To control the Z feature, I would like to view it in 3D - but that is not possible. Is this a fundamentally different function in AGP compared to ArcScene? Am I doing something wrong?
Thx
Frieder

Hey Ayan,
trying to move the "Abfahrt_sections1_z" Layer to "2d-Layers" does not change anything - BUT:
Moving it back to "3d-Layers" will show the Z-feature wit its origin z-values - hobering above my TIN - like it does in ArcScene. 
But this seems to be a workaround. I do not understand why it behaves like it does.

Sorry - you get me wrong. Thats exactly what I am talking about. 
the "Abfahrt_sections1_z" is a 3D-layer. And it is nor terferring to the Grund-Elevation. It has its own.

For better understanding:

The Ground Elevation TIN is a Quarry and the Z-Line Feature "Abfahrt_sections1_z" is a constructed road down to the bottom of the quarry. I cannot refer the elevation of the road to the surface of the quarry.

In ArcScene both features - the TIN and the z-Line - are beeing displayed in their right 3-dimensional postition - without referring them to some ground elevation (see screenshot)

@FriederDaeublin Try moving the Layer "Abfahrt_sections1_z" under 2d Layers.

Also select the appropriate option at Layer Properties > Elevation > "Relative/On the ground". Try different options here.
