Getting started in BIM 360 Plan begins when you receive an email invitation to join a BIM 360 Plan project.
As a collaborator, you first receive an email invitation from an organization such as a general contractor, engineering firm, or owner organization. From this invitation, sign in to your BIM 360 account using your Autodesk ID, which is a combination of your username and password. This ID gives you single-sign-in access to multiple Autodesk sites.
In the Welcome to Autodesk BIM 360 Email, click the project link or the Get Started button to launch Plan. Each welcome email is meant for only one user. Do not forward it to others.
Sign in to BIM 360 Plan with your Autodesk ID.
If you forget your password, click Forgot Your Password and enter your email address. Look for an email with your ID and instructions for resetting your password.
If you don't know an Autodesk ID, click Need an Autodesk ID. Then enter your information and click Create.
If the user name is already in use or the ID is associated with your email address, you are prompted to try again. To verify credentials or reset your password, go to http://accounts.autodesk.com.
