NX 7.5 : STEP data is "Hidden" and in black. I can't show him

[marcmata]

Hello,

I opened an STEP file using NX7.5. After a while the translator finished. It's a huge assembly but I can only see a tube?!? So I double-clicked a part in Assembly tree and suddenly apeeared a new part, all in black. But when I return to Top assembly it dissapeared. All the parts are there, only visible if you click "Make displayed part", but are invisible in the top assembly.

I used Show and Hide and nothing is hidden. I saved the STEP assembly as a part to work with a native .prt, but components are still hidden...

So I don't know where is the problem. The data is there but only if you use "Make displayed part". I want to create a JT with all the data and I only can get a tube...

Thanks,

Regards.

I got a clue. The STEP created a reference SET. I need to change all reference sets to see all the parts.

Regards.
