2.2 - Isometric Sketches

Introduction:

Mechanical drawings are one of the most important skills a new engineering student can develop. They are essential to being able to communicate effectively and to define a design for manufacturing. Isometric Sketching is the most common format of 3D drawings for engineering. In this activity you will begin developing your isometric drawing skills.

2.2a - Isometric Part Combos (ENET) 

Presentation:

Here is a video that talks about why we use Isometric Drawings in Engineering. 

In this activity you will be given a set of ¾ in. plastic interlocking cube blocks. You will brainstorm as many part combinations as possible using only three of those cubes. You will sketch your part combinations on the isometric grid paper provided. Make sure that you document each combination that you find. You will perform the same process using just four cubes, then with five cubes, and finally with six cubes. It is important that you identify as many combinations as possible for each set of cubes. The goal is to come up with more combinations than your classmates.

Minimum requirements are:

• Create and draw all 2 different permutations of 3-Block Parts

• Create and draw all 8 different permutations of 4-Block Parts

• Create and draw at least 3 different permutations of 5-Block Parts (Make these on your own)

• Create and draw at least 3 different permutations of 6-Block Parts  (Make these on your own)

 Present your findings to the teacher for review and take a picture of the sheet for your Engineering Notebook.

Use Isometric Graph paper to draw the different combinations:

Once you have competed your drawings make sure to take a picture and post it to your Engineering notebook.
