Is there another way to "weld" physics enabled static meshes together, or am I using constraints wrong?

I tried to use that attach function in multiple ways without ever seeing it doing anything at all. I know that to grab an object I had to use a PhysicsHandle and manually update the position in Tick. But as that AttachActorToActor (in BP) function seems to take a positioning argument I thought it would update automatically (like a model with bones) but it doesn’t.

Meaning that this is totally useless:

By adding a PhysicsHandle to the parent I could not move the child away. The parent could be moved but the child wouldn’t move with it. Rama could you please enlight us here ?
