Microstation Connect Edition - Solids/ 3d objects display without some graphics when referencing files

Hi,

When I reference one file to another some graphics disappear please see link below:

(1) Microstation Connect Edition - importing a parasolid & referencing to working file - MicroStation Forum - MicroStation - Bentley Communities

I first thought it had to do with parasolids only but when I import to certain files this happens. I did play around with the visualization setting but it make no difference. Also I made sure to use a 3d seed file but am unable to reference the file (where I imported the parasolids at first) that it displays correctly in my working file.

Thanks

Johann
