Character size + preserving FBX coords from F360

Hi all,

I’ve modelled a house in Fusion 360 and I have two problems using this in UE4, one serious and one minor.

Serious one first: despite checking the size of the geometry in Unreal, the house seems TINY. The default character can’t fit through most doorways, even though they’re 0.9m wide. What size is the character? Is there a way to scale it down to a normal human if so? What do archviz types do here? Even if I started from scratch in UE4 I guess I’d hit the same problem because I think the geometry was imported to the correct scale.

Secondly, when I export FBX I end up with a bunch of separate objects. I guess I could try to note their positions and orientations in 360, but this will take a LONG time. Is there any way to preserve the relative positions of the components of my house?

Thanks!
