Lesson5:DealingwithPrimitiveShapesIn this lesson you will learn:

1- How to use the primitive menu to select 3D objects (basics shapes) and place them on the grid.

2- How to move 3D shapes and objects around the grid. 3- How to rotate 3D objects to get a view from all sides. 4- How to scale objects and change their size using measuring tool.
