The key points discussed in this tutorial:
Let's add a primitve in our scene. We'll start with a box. To do this, go to the Create Tab , click on the 'Box' box :D, move your mouse in the viewport, leftclick and hold while you drag the shape of the box. Once you have the square, you let off of your click and drag up your shape, click again and the shape is created. Rightclickto get out of the 'Box Creation' mode. (Well that was a mouthfull)
To create the other shapes in Standard or Extended primitives, just repeat the same process. Do this a few times to get used to it.
If you click on one of the created shapes in your viewport, on the Modify Tab you have a few parameters you can change that trasnform the width, height, lenght of the object or you can also add more segments aka more geometry. You'll see why that is important later, but basically, the more segments you have, the more polygons you have which means you're adding geometry to that object. Now you can manipulate tinier parts of the object.
Now that we have some 3D objects inside our scene, how do we manipulate them?
Lastly, modular modeling is an important part of environment modeling. Modular modeling refers to creating a few shapes which then you can later combine in different and multiple ways to create full environments instead of creating everything from scratch again. Saves lots of time. That's why duplicating an item is quite important. To do that, select an object, hold down SHIFT and move, rotate or scale your selection.
A tiny box with the following methods appears: Copy, Instance, Reference.
The Copy Method creates a separate clone from your original. If you modify your original, it won't affect your copy. It is basically an independent master object.
The Instance Method creates an interchangeable clone of the original shape. Modifying your instanced object means modifying your original.
As promised in the video, the Reference Method creates a clone that's dependant on your original. If you change parameters to modifiers that were applied before you made the instance, it will change both objects. If you apply a new modifier, it affects only the object it's been applied to. We'll see what modifiers are in the next video. (those options I told you about that will transform the shape of our 3D object in one way or another).
