Which function would you use to create a new user interface design from scratch?

The function that allows you to create a new user interface design from scratch is the option to start a new project. This function is specifically geared toward initiating a new workspace or framework where you can begin the design process without the constraints or elements of an existing project.

When starting from a new project, you have the flexibility to build your interface according to your specifications and requirements without any pre-defined components or settings that might come with modifying an existing design. This approach is essential for projects that require a unique design or layout tailored to specific needs, facilitating a fresh canvas to work with. Additionally, it allows for creativity and innovation, which are vital in developing effective and user-friendly interfaces.

In contrast, options like modifying an existing design, importing a design, or exporting a design are meant for altering or transferring existing designs rather than starting anew. These functions serve specific purposes in using or sharing designs that have already been created.
