I know this is a simple question, but I cann't find the right words to describe the missing menu that pops up when you Add Mesh. What is it called? How do I get it back?
Background
In a recent file, somehow I broke the system and when I add a mesh the window that pops up to give configuration options is missing.
What is this pop up window called?
Where do I go to add this back?
For example, I need this menu to change a circle into a hexagon. In the menu there are the number of vertices that I can change from the default of 32 down to 6 or 8.
