Activity 2.5 Sketching Practice Answer KeyIntroduction
Sketching is a valuable engineering skill that needs to be developed through practice. Through practice you will be able to communicate your vision of your idea.
In this activity you will apply the skills that you learned earlier in this lesson to more complex objects.
Equipment Pencil
Procedure
Each of the following nets can be cut out and folded into a box. Note that there may be more than one square on each face of the box once constructed. Sketch an isometric pictorial sketch for each of the boxes formed.
