Problem importing FBX

Hi,
It seems D5 suddenly (after upgrade to 1.4) cannot import fbx files for me. They were generated with different software (archicad and maya) so I don’t think the fbx is a problem. Any other format for transfer?
Thanks!

In archicad i export in sketchup format, works for me.

Hi, yes, it works with sketchup.
However SKP only works as an option when starting a new project and not with importing nwe meshes in existing projects. Please correct me if I’m wrong.
Thank you!
