RESEARCH · REFLECTIONS

From this lab I've learnt to use the extrude tool to pull out the shapes you want from the object. 

FOR EXAMPLE: 

The above pictures shows that the sharp edges are pulled out by using the extrude tool. 

FIRSTLY, WHAT IS EXTRUSION?

Extrusion, basically means "to thrust out", refers to both to the process in which material is forced through a die or series of dies in order to shape it as well as to the product of that operation. The shapes most often produced in this way include round objects like tubes, rods, and pipes, rectangular objects like solid and hollow bars, and plates. 

PROCESS ON HOW I EXTRUDE OBJECTS.

HOW DO WE EXTRUDE?

1) Create a cube in any size, the cube must be in object mode. 

2) After creating the cube, we need to click on the inputs at the right and edit the subdivisions.

Remember to insert the subdivisions so as to allow the cube to be divided into a few parts.

WHAT DO I MEAN??

It means that for example if i insert 3 into "Subdivisions Width", 

it will divide the big cube into 3 parts across it's width. 

3) Change the "object mode" to "face" by clicking on the right mouse button. 

Select the faces that you want to extrude. Hold on to "shift" while selecting multiple faces.

4) Click on "edit mesh" on the menu bar and click on "EXTRUDE".

AFTER EXTRUDING IT WILL BE LIKE THIS: 

WHY DO I THINK EXTRUDING OBJECTS IS IMPORTANT?

The need to extrude the objects is important as it save all the tedious work by adding and creating another objects to combine it with the original one. By extruding, we can have the shape we want without having the need of adding another shape to it's original one. For example, my gear, i need the sharp edges at the side, hence i select the faces after inserting the subdivisions. As a result i have my gear with the sharp edges.
