Yes, project sharing in Detail is possible.
Important: You'll need to create a Detail account for this.
From the library view, long-press on the project you want to share, then tap Upload Project.
The app will upload the project to your account profile and immediately enable you to share the link with someone.
When this person opens the link from their iPhone, it will open a copy of the project on their device.
Important: changes made on this copy will not affect the original project
