In order to access a project in StreamBIM, you need to be registered as a user with a valid email address. There are two ways of registering as a user:
1. Be invited to an existing project
In order to access an existing project, you need to be invited (to your email address) by one of the admins in that project. See the article How do I log in for the first time from an invitation?
2. Register your own project
You can also register as a new user by setting up a completely new project from scratch. Click here to create your own project (10 day free trial).
