You can invite users in Trimble Connect for Browser 3D Viewer. If the invited user already has a Trimble Account, they will receive an email with the project link. Otherwise they are instructed to create a new account. When the users have joined, they can access the project and the folders and the files to which they have permissions to.
While inside the 3D Viewer, click the Settings button in the toolbar.
Click the Invite people to project button at the top of the panel.
Note: If the user does not have a Trimble Account, the user's status appears as Activation Pending until the user has an active account.
Project Member Invitation Settings
Some projects may require more strict control for inviting users into the project. A Project Administrator can select the option to allow all users to invite new project members or restrict project invitations to Project Administrators only for enhanced security.
If a Project Administrator has restricted this functionality, the Invite people to project button will be disabled/not work.
