Currently unloaded objects in Pro, once SP is uploaded to 4d review, will show as loaded therefore displaying and visible. User will need to manually select these objects every time to hide those objects when opening the 4d review session.
If user does not want to see the objects in 4d review at all, she needs to delete the object in the .sp.
What user sees and saved in Pro should match what user sees in 4D Review after upload.
Thanks for submitting the idea. It will not be considered at this time - we will consider it if there is more need from users.
