Introduced herein is a platform with multiple graphical user interfaces (GUI) for rapidly designing, editing, and sharing of a three-dimensional (3-D) design. A GUI can include a menu with add-on elements and a display interface to depict the 3-D design. A user can select add-on elements to build a 3-D design, view the environment at different angles, and interact in other ways with the 3-D design. Additionally, the platform enables multiuser collaboration within a collaboration GUI to allow for input from multiple users. The platform generates a join code which can be shared with multiple users and is associated with the collaboration GUI. A user can join the multiuser collaboration to view and edit the 3-D design simultaneously with multiple users. Each user can view the 3-D at their own angle and view each other's edits in real time.
