select anything else or perform another operation, that menu

disappears.

Tip: If you accidentally close the menu by selecting other objects, you

can call it back by pressing the F9 key. However, it will only work if you

don't perform any other operation. The F9 key calls the "Adjust last

operation…" option.

In some cases, you must use the menu to make adjustments to the

object. For instance, you can create a square from a Circle. Create a

Circle from the Mesh group and set your Vertices option to four (Figure

2.3).

That results in a square, which is similar to a Mesh Plane that only has

border edges.

For each object created in Blender, it is possible to view and edit some

of their properties straight in the 3D Viewport. For that, you must use the

Sidebar by pressing the N key (Figure 2.4).
