How to create and model mesh

Hello,
Maybe it is so simple but I search Google long time and can’t find answer.
I can only import any mesh. But:

How to create mesh, model and edit it like in Blender? Is this possible in UE?

Kind regards,
Simon

You can create bsp objects in the engine.

But,it’s build time higher than normal meshs.

You must use a 3D modelling prog.
