Hi Enscape,
Please add a tab in the exported .exe files to show collaboration options!
It will help tremendously in coordination process!!!
So that:
If I export an .exe file to a consultant,
they can open it up and spin around in it and look at my markups in 3D!
Cheers.
Welcome to our forum, I’ve gladly forwarded your feedback accordingly.
This is also already filed as a feature request, so I’ve added your upvote to the topic on our agenda. 
Should just be a matter of time until we’ll implement this, but there is no exact release date yet.
