Dear support,

I am facing an issue retrieving metadata from jt file. I used hoops c++ functions to retrieve generic attributes (based on sample source code) but some metadata (obviously custom) aren’t retrieved. Hoops Demo Viewer is retrieving them.  
Is there a different API (or loading options) to get them?

Thanks  
Regards,

Hi @gabriel.peragine

I am facing similar issue. Could you please help ?

In my case i am getting metadata for some PO items partially only . .  
like 11 atribubtes.  
But when i check the hoops demo viewer for the same item . the metadata seems to be more with names like designer names and much more infos.  
Do i need to search for datas somewhere else. ?

I am using the hoops . (2024.6.0)

Hello,  
Have you tried traversing all Product Occurrences, including the Prototype? You may want to check the CAD file using the default example **PRC2XML**. If the issue persists when using PRC2XML, could you provide your CAD file for further analysis? Thank you.

Best Regards,  
Man

This worked perfectly well for me. What i have missed is getting the attributes for the Prototype type entities . Now i could get all the missing attributes properly .  
Thank you so much .
