Hi @Ushin ,
so far, I see you data is coming form Catia /reiht?
When we import some data what is not pvz the Vuforia Studio will convert the data to pvz to the upload folder of your project - example: ..\VuforiaStudio\Projects\<projectName>\src\phone\resources\Uploaded
So the question is when you upload this file is there a pvz file created. Could you open this file with the Creo View or in Illustrate and what is the display.
so I do not have much experience with Catia but I think in Creo parametric we can face the same problem when we do not have all dependent models in the selected folder or in the folder specified by the current path. Because in the Cad application you will be able often to open an assembly where the different components are coming from PLM or on some setting which are known only for the CAD application (e.g. in Creo the search_path in the config.pro ... etc)
Therefore, we cannot be sure if in a folder the data is complete with dependencies. In Creo I could export the data via backup functionality to a folder. Unfortunately I have No Idea what is the corresponding feature in Catia
