When I import .obj file that I exported from Adobe Fuse but when I add it to scene it is invisible - I see only X Y Z arrows.

That is what it looks like.

Sounds like a scaling problem. Either it’s very big or very small. Try pressing the F key with the scene view active to make the camera zoom to fit.

Failing that, check the material. It may be transparent.

Also for a sanity check you could try opening the obj file in blender. It’s a free modelling app.
