How Can I start a project on the window?

I cannot find the place that I can start a project?

There are multiple ways to do it.

On the Recents page, you can click either on the + button on the top right, or the blue button on the middle buttom:

On the Designs page, you can use the + same as on Recents, or the blue button in the middle:

You can also import an existing model using the import button next to the + one, or double clicking on an associated file in Finder.
