If you already have an account, enter your password and log in.
If you do not already have an account, you will be prompted to enter your name and create a password. From there you will pick which plan you want and check out. After checking out, you will be redirected to Davinci. Follow the link above again if you are not automatically redirected.
Once you are in the Project, you can begin creating your Model. Go to the Chat Bar at the bottom and try asking Davinci to build a simple parts tree. Press Enter to send messages to Davinci.
Once the task is compelete, you will see new objects populated in the Model Index. You can either interact directly with the objects by clicking on them in the index. If you want to focus specifically on what Davinci created during that task, you can click on the View button in the Chat response to see a change log of the modifications.
