Is there a way to view all the history that one has done on a project, all of a sudden some of my piece got deleted some how and i dont know how to get it back, and i want to know if i can view the entire history to see how to get it back.
You can look at the undo history but it is limited to a certain amount of steps itemized in the preferences as it takes up memory. Undo history is not wiped on each save.
A good habit to get into is to save your project with a name that makes sense according to the stage you're at with it, eg "Project -BVs recorded". Then if you need to go back to something you can go and grab it.
