ShaperHub provides an easy way of getting files to Origin. First, log in to ShaperHub.
Then tap your profile icon in the top right corner of the header.
Select My Hub. You'll see a list of all of the projects you've added to My Hub (signified by the Folder icon), as well as all the individual files you've uploaded.
Now, tap Upload. You'll see a file upload dialog appear.
Select the file you'd like to upload and select Choose.
The file you uploaded will now be available on Origin when you navigate to the My Hub tab in the file browser.
