Generate a new (empty) component
You can create a component as an empty dataset in the sense of a "entry anchor" for the functions of the component browser. The first step is to create a kind of component envelope with its own component ID, which now has to be filled with content. You might start by using a generic symbol or by clicking in the browser on the area where you would expect the symbol (bottom left) to edit it.
