Hi team:  
I tried to get meta info from a .sldasm file via hoops exchanger demo PRC2XML. I can only get one mate from root occurrence. And from solidworks plugin, I can get more mate info. How do I write my cpp code to get all mate info from .sldasm file? Could you give me some example code?

Thanks

Hey @Undefined!

First off thanks for your post. I’m honestly not sure if mate data is something we pull in. I’m asking some of my colleagues and we’ll follow up here.
