Hi, I think the Unreal Editor is missing some basic tools such as alignment of meshes. I use Sketchup a lot and just recently started using Blender. As a developer of many years, almost all of my IDE’s (RAD) also support this type of functionality.
As I would see it, selecting 2 vertices on one mesh, and 2 points on a second mesh, pressing the a new align button would do the obvious on any of the 3 planes X, Y & Z.
The Unreal Editor is packed with features and covers a huge range of topics. I think for new users of the Unreal editor that they would spend many hours looking for these types of tools.
