3d Coat Applink Questions

How does 3D Coat applink work ?

I am attempting to develop a workflow where I model in Nvil, uvmap and texture in 3D Coat and export model & textures from 3D Coat to Blender for rendering in Cycles.

I have 3D Coat applink enabled
I have 3D Coat running on the system
I select the objects I want to uvmap in Nvil
I open 3D Coat applink settings in Nvil > click perform uv mapping in 3D coat.

Nothing happens in 3dc is it supposed to ?
