Rendering simple shapes procedurally

I see this tutorial :
https://docs.unrealengine.com/latest/INT/Programming/Tutorials/Components/1/index.html
There is section :
static ConstructorHelpers::FObjectFinder SphereVisualAsset(TEXT(“/Game/StarterContent/Shapes/Shape_Sphere.Shape_Sphere”));

I’m using the same code to load simple shape.
I’ve copied Sphere.uasset from :
Engine/Content/BasicShapes/Sphere.uasset
to my game subdirectory:
/Content/BasicShapes/Sphere.uasset

Now I just want to load this asset, but whatever path I will specify in place of :
“/Game/StarterContent/Shapes/Shape_Sphere.Shape_Sphere”
it never works.

I find it very hard to display simple Sphere/Box that I could specify size procedurally for debugging.
DrawDebugSolidBox is not good enough as it’s not taking rotation into notice.
Why so simple task is so hard in UE4? How I can render simple shapes ?
