Can’t open Fbx files

Hi, i try to open some fbx files generate with vectorwork and d5 stop loading at 30%. I also tried to open an old fbx file with which I have already made renderings in d5 but this also stops at 30%. I started d5 as administrator and updated the graphics card. any suggestions?
Tks

I forgot, when I open a new project in d5 by opening the fbx file it seems that it loads the project but when it opens it is completely empty

Try downloading AUtodesk FBX converter here:

Install it and try converting your FBX file into another version (i.e. version 2013) and try loading the converted file instead.

With this program you can also converte obj and dae files into compatible FBX meshes.

Turn on the normals and tringulate in the fbx export settings

I finally found the problem, there was two object (strangely two simple parallelepiped) that create some problem in the file. The oddity is that all the other programs opened the fbx file without problems, thank you for the suggestion.
