I have an asset from an outside tool which can generate a point-based mesh (i.e., no triangles). Blender is able to view this beautifully. See Below.
Question: Is there a way to import this wireframe type asset into UE? When I attempt to do so I get the no triangles error 
Alrighty, not sure about an in editor solution but I did find a #Blender solution which seems to work really well!!! Yeah for open source tools!
Solution to all your woes (ok, maybe just some):
Open up your wire mesh in Blender
Delete any vertices you don’t want and then in Object mode select Object>Convert>Curve
Select the mesh and go to Object Data Properties>Geometry>Bevel>Round>Depth and set it to a number that works for your level.
Export the mesh in desired format (e.g., File>Export>glTF 2.0)
Import into Unreal Engine (Add/Import)
Marvel at your beautiful creation!
