Process
Final
In this exercise, mainly is to select the faces of the gears and extrude them. I learnt a important lesson which is Shift-select. At the start, when we select two groups of faces and then second another group of faces that are not selected in the beginning, afterward, it will be toggled. Which means, selected faces become unselected and unselected faces become selected.
Also sometimes, when we select the blocks at the front, some blocks at the back might be accidentally selected. So we always have to rotate the camera and avoid wrong faces.
To extrude the faces outwards to create the teeth, we select the faces that we want to extrude then click on edit polygons and extrude face. A extrude manipulator will appears and we will just have to scale it.
For this exercise, a step-by-step video tutorial is given to us. In this video tutorial, instructions are clear, I am able follow the step and complete the gears. I prefer learning in this way because I am able to keep up with the speed of teaching as I can pause and replay the video if I don't understand a certain part.
